Battery installation into mavr-3m Move the battery compartment slider aside in the bottom part of the recorder case. Place the recorder and rechargeable battery as shown on the figure below. Insert the battery into the recorder up to the stop. If you made so, both LEDs will start blinking. Then mavr will turn to stand-by mode. Put the battery compartment slider to the original place. To avoid the early discharging of the battery do not leave it on metallic surfaces and do not close the battery contacts with metallic items. Battery charging The battery charging can be made from power network or PC USB port. The shipment set also includes the charging unit, which controls the charging process. The charging block has two LEDs for charging process indication. The red LED indicates that the charging process is going on. The green LED indicates that the charging process is stopped. This unit disconnects the charging current automatically, so there is no need to look at the charging end. The charging time of the fully discharged battery is 5-6 hours. The battery charging order If the charging is carrying out from power network, then connect the power adapter to the charging unit and plug the adapter into the power network. The LED on the power adapter will go on indicating the power connection. If the charging is carrying out from a computer, then connect the supplied cable to USB port, and another end of the cable to the charging unit. The red LED will go on for a short time on the charging unit and then the green one will go on constantly. After this, 10

11 connect the charging unit to the recorder. The red LED will go on on the charging unit, indicating the charging process. If the red LED does not go on, but the green one continues to light, so the rechargeable battery is completely charged. Upon the charging finished the red LED goes off and the green one goes on. After this disconnect the charging unit from the recorder. Attention!!! Li-Polymer rechargeable batteries fall out at deep discharging, thus it is necessarily to charge the batteries from time to time, at least once per month. It is strongly forbidden to use other charging units, than the supplied one. Do not connect any power sources directly to mavr-1 or mavr-3m (with installed battery) to avoid battery fall out. Warranty does not cover the rechargeable batteries, fallen out due to deep discharge or use of the wrong charging unit. It is possible to record and charge simultaneously. To do so, connect the video output of a camera to the video input of the charging unit and supply power on the charging unit. At the battery discharging with connected charging unit, the charging will switch on automatically. Also it is possible to connect video signal output from a video camera directly to the recorder, using video cable from the shipment set. And supply power to the camera.

Format the card into FAT16 or FAT32. (FAT and FAT16 are two names of the same format) For this insert it into the CF card reader (the reader is not included into the shipment set and can be obtained separately), open My computer, properties and check the file system type. For operation with mavr the CF card must be formatted with FAT16 or FAT32. If required, reformat Start

13 the card into FAT16 or FAT32 with standard procedure of the operational system. Then it is required to initiate the card (prepare for recording). For this run the program mavrmanager, choose the letter of your CF card reader and press the button InitCard. After the process finished successfully, the CF card is ready for operation with mavr. Before removing the card from the reader, it is required to carry out the safe removing. For this make the right button click the reader shortcut and choose the Remove command. After this you can remove the card. The information on the CF card is used in the special format of mavr, thus for playing back by the regular Windows programs please use the recoding program mavrdecoder.exe (it is saved in the mavr directory on the supplied disk). Installation and removing the CF card Installation and removing the CF card can be made only in the stand-by mode of the recorder (rarely blinking green indicator). In case of improper installation or removing the card, the card can be damaged. For installation the card, place it in front of CF card compartment with contacts directed to the compartment and face up. The card should be installed without significant efforts. If the card cannot be installed, turn it over. To avoid damaging of the recorder please do not place any exterior items, and more other metallic, inside the battery compartment of the recorder Operation modes The LED indication of the modes is described in the table in the end of the manual. In the same table there is given information on the recording start. Stand-by mode Initially the recorder is in the stand-by mode, with minimal power consumption. At this rarely blinks the green LED, the red LED is off. If the red LED blinks rarely, that means that the rechargeable battery is strongly discharged and it is required to charge the battery. From the most modes, the recorder switches over to the stand-by mode after a certain period of time at the absence of control actions or at the allocated memory is finished. The control actions for switching over into the stand-by mode from other modes are described in the appropriate parts. From this mode it is possible to switch over to the Active mode by press and hold longer than 2 seconds of any of the buttons Rec or Stop, also into the recording mode by the external switch Start. The recorder initializes itself during several seconds, during this time the green and red LEDs blink frequently. After this the red LED goes on during the card format analyze. Depending on the card volume, this time can vary from a second in the case of the right format, and up to several seconds in the case of the wrong format. After analyzing, if the card is not inserted or the format is wrong, the recorder returns to the stand-by mode. Active mode This is the mode when the recorder is ready to record. The red LED blinks with the series of 1..4 flashes with a pause between the series. The quantity of flashes indicates the rate of the battery charge. The more flashes the more the charge. The green LED blinks rarely. From this mode there are possible the switches over to the following modes: - Stand-by mode press and hold of the Stop or Rec button during 2 seconds. 13

14 - Record mode short, sec, press and release of the Rec button. - The record profile choice press and hold longer than 3 seconds the Rec button. - Erasing of the last recording press and hold longer than 3 seconds the Rec and Stop buttons. - Erasing of the complete CF card press and hold longer than 6 sec the Rec and Stop buttons. - Time setup press and hold longer than 9 seconds the Rec and Stop buttons. If the recorder is in the Active mode longer than 5 minutes, than it automatically switches over to the stand-by mode for saving the battery charge. If voltage of the rechargeable battery achieved the minimal level, so the recorder automatically switches over to the stand-by mode to avoid the failure of rechargeable battery and CF card. At this the red LED starts blinking rarely. Recording mode Immediately after switching over to this mode, the green and red LEDs go on for a second. During this time the recorder initializes the record block, after this the record starts. The green LED indicates the relative frame frequency, the red LED indicates the amount of the rest space on the card (the more flashes, the more the space). If press and hold the Stop button, so the red LED indicates the battery charge rate. To stop the recording press and hold the Rec button during 3 seconds. So the recorder will switch over to the Active mode. Also mavr automatically switches over to the stand-by mode at achieving the end of free space, when the Linear record mode is set in the current profile. Recording mode by the external switch Start Recording start from the stand-by mode is possible also by switching on the switch Start. Recorder activates and recording starts immediately. Recording goes on till the switch Start off. After this mavr switches over to the stand-by mode. If earlier the record pointer achieved the end of the card in the Linear mode, than the recorder does not on by the external switch. Selection of the recording profile mavr supports the active switch over of up to 8 recording profiles. The profiles are set with the program mavrmanager.exe. Using the profiles it is possible to set the following recording parameters: video resolution, video quality, frames per second, linear or circular recording mode, colour or black/white, audio sample rate and so on. There are the preset profiles as well as the possibility to create the profile by a user himself. Selecting the circular recording mode the recorder uses free space of a CF card, which was available at the moment of the record start. For example, before starting recording in circular mode there is 40% of the card space already allocated for previous recordings, so only the rest free 60% of the card space will be used for recording in circular mode. If it is required to use the complete volume of the CF card, so you need to erase the old information on the card before recording start (see the part Erasing of the complete CF card). To select a preset profile, created in the program mavrmanager (from 1 to 8) in the Active mode it is necessary to press and hold the Rec button during 3 seconds until the both LEDs will go on. Then release the Rec button the LEDs will go out and in half a second the green LED will start blinking rarely. Quantity of flashes until the repeated press of the Rec button corresponds to the number of the selected profile. For example, you need to select the profile No 3, so it is required to count 3 blinks of the green LED and press Rec button. After this the recorder switches over to the Active mode. 14

15 Erasing of the last recording In the Active mode press and hold the Rec and Stop buttons (during this time both LEDs are on constantly). In 3 seconds both LEDs start blinking rarely and synchronously. If now release the Rec and Stop buttons, so the last video recording will be erased (physically it is not erasing just the pointer moves). After this the recorder switches over to the Active mode. Erasing of the complete CF card In the active mode simultaneously press and hold the Rec and Stop buttons (during this time both LEDs go on constantly), in 6 second the LEDs will start blinking frequently. If now release the Rec and Stop buttons, so all the recording on the card will be erased (physically the recordings are not erased but the pointer moves into the beginning of the card). After this the recorder will switch over to the Active mode. Note. When you erase recordings by the mentioned above method, so physically the recordings are not removed from the card. In this case you just set recorder to start new recordings over the old one. Thus if you make decoding of the card content without doing new recordings, so in result you will get the old records, which you wanted to erase. To physically erase the recordings from a card it is required to initialize the card. Time setup In the Active mode simultaneously press and hold the Rec and Stop buttons (during this time both LEDs go on simultaneously), in 9 seconds both LEDs will go on constantly again. If now release the Rec and Stop buttons, so time will be set up, which was recorded at the CF card initialization. After this the recorder will switch over to the Active mode. If time is incorrect, that can happen at the first power on, so the recorder automatically set time 00:00:00 01/01/04. Take a note, that exactly those time and date will be set which were displayed in the field Time, time correction, date of the mavrmanager program at the moment of the initialization start. Thus it is required to set exactly that time in this field when you will set up time on the recorder. I.e. at the card initialization it is required to calculate in advance the period of time required for time set up. 15

16 Accessories to mavr The accessories are optional, not included into the shipment and can be purchased separately: External microphone with integrated compressor (+/- 6dB) and remote control unit This optional device is intended for use with the audio video recorders mavr. The device is external microphone with compressor integrated with remote control and video input. External microphone smoothes audio level when recording is carried out from sound sources at close and distant ranges. Thus this enables to avoid overload when recording is realized at close distance and amplify the signal at distant ranges. Flexible cable enables to arrange the microphone at the suitable-to-record place and remote control unit simplifies recording process. The unit connects to the recorder socket and automatically switches over the built-in microphone. Usage of the unit allows improving quality and dynamic range of the recording audio. The remote control provides the possibility to easy turn on / off recording (see Recording mode by the external switch Start). It is worth to note that record does not start immediately after switching on the remote control, but in 7-10 seconds. This time is required for switching over the recorder from stand-by mode to record mode. Video camera power supply unit The voltage converter for video camera is designed to be connected to mavr video recorders. The unit is a voltage converter, which allows the video camera to be powered from the mavr power source, and generates voltage of 12 V (200 ma) on its output. The output has a connector for the video camera. Besides, the unit includes an input connector which completely replicates the one on the video recorder, and makes it possible to use an external microphone and remote control. Therefore, the user may have a stand-alone system to record video and audio without using any additional power supply units for the video camera. Note, usage of the converter results in the battery life reduction proportionally to a camera current consumption. Car power supply unit 12 V The car battery charger is designed for connection of the mavr video recorder to the car on-board power supply system or any other power source with voltage 7-28 V. The unit provides complete mavr battery charge within 5-6 hours or its recharge during recording. The unit includes two LEDs to indicate the charging process and a cable to be connected to the power supply. Besides, it has a USB mini-b connector, which fully replicates that on the video recorder and enables various mavr accessories (e.g. an external microphone and remote control) to be used with the unit.

17 Software and its updates To look through the made recordings, for video recording profiles setup, the following programs are installed on a computer: - CF card Initialization program - mavrmanager - Program for audio video recordings decoding - mavrdecoder - Program for video verification - mavrchecker These programs are supplied on a CD and located in the folder mavr. Description of how to use the programs is also located there. For the programs installation simply copy the folder mavr onto your HDD.
