2 2 WT-500 International Travel Tour System OKAYO WT-500 series can be use up to 15 hours with only one battery. This feature helps the tour to reduce the extra battery weight and cost. It is only 70g which brings comfort for the users without adding extra weight to their vocation. The channel auto locking function prevents channel changing on mistake and the back lit LCD help users to read the channel number better during dim environment. When necessary, users may connect WT-500 to an external audio input. The usable frequency range is from MHz. Forty to eighty channels are available to choose from. One may use groups of channels on the same occasion. The transmitted range is as high as meters. One transmitter WT-500T within the effective range can be used with an unlimited number of WT-500R receivers. We offer leasing service for this model.

4 4 DGT GHz Digital Tour Guide System Advanced 2.4GHz digital tour guide system is designed in a digital radio transmission technology with more channels for multi-groups to be used simultaneously up to 256 channels. No interference, no conflict frequency, it is license free while using DGT-2400 digital group tour guide system, speaking quietly, without effort by a guide and have every member of the group hear you during visits in indoor or outdoor activities. The system is capable for international conferences and to solve multilingual translation problems. DGT-2400 adopts 2.4GHz digital transmission technology and provides 256 channels to facilitate search of undisturbed channels. One DGT-2400T transmitter can be used with multiple DGT-2400R receivers to provide a more economical solution. In an open area without interference, the transmission range can be up to 100 meters. The LCD back-lit panel will display the current channel and battery residual quantity.
