1. Assembly (Skipping this can lead to troubles! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: A good quality soldering iron (25-40W) with a small tip. Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called thinning and will protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning. Thin raisin-core solder. Do not use any flux or grease. A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they cannot fly towards the eyes. Needle nose pliers, for bending leads, or to hold components in place. Small blade and phillips screwdrivers. A basic range is fine. For some projects, a basic multi-meter is required, or might be handy 0.000 1.2 Assembly Hints : Make sure the skill level matches your experience, to avoid disappointments. Follow the instructions carefully. Read and understand the entire step before you perform each operation. Perform the assembly in the correct order as stated in this manual Position all parts on the PCB (Printed Circuit Board) as shown on the drawings. Values on the circuit diagram are subject to changes. Values in this assembly guide are correct* Use the check-boxes to mark your progress. Please read the included information on safety and customer service * Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as NOTE on a separate leaflet. 1.3 Soldering Hints : Mount the component against the PCB surface and carefully solder the leads Make sure the solder joints are cone-shaped and shiny Trim excess leads as close as possible to the solder joint 3

20. HOOK-UP AND USE Power supply : Batteries : 4 x 1.5V AAA (use included battery holder) Idle power consumption : 15µA max. Record power consuption : 26mA Playback : 50mA max. Transformer : secundary : 9 to 12VAC Idle power consumption : 7mA Record power consumption : 40mA Playback : 75mA max. Hook-up of one unit : Mount wire jumpers JR & JE For message auto-repeat, connect RPT to STRT (by means of a switch) RPT and STRT must not be connected during message recording. Hook-up of two or more units : Mount JR and JE on the last module Mount JC on the other module(s) For message auto-repeat, connect RPT of the last module with STRT of the first module. During replay, a click sound is heard at switchover between two units. If 5 or more units are put in cascade, the voltage regulator (VR1) of the first unit needs to be cooled with a small heatsink. Signal input : Microphone : Mount wire jumper JM on the first module. Line input : Enter the audio signal between AIN and GND Max input level : 25mV rms Signal output : Loudspeaker : Connect an 8 ohm loudspeaker between SP- and SP+ of the first module. 12
Line output : A line level signal is available between SP+ and GND How to record a message : Put SW1 in the position RECORD LD1 lights Press SW2 to record Releasing SW2 will end the recording session LD2 lights when the memory is full How to replay a message : Put SW1 in the position PLAY Press SW2 briefly. (Do not continue to press SW2, it will lock-up the unit) The message will be played, and will end automatically Optional rotary switch : Add this switch to divide the recording time in 5 blocks. Select a block by turning the switch to the desired position Each block can have a different length 21. PCB LAYOUT 13
