Tx/Rx Listening Devices

Sound is filtered and 100% buzz free for perfect audio clarity. With mains power you no longer need to recover and recharge the unit making it perfect for long term monitoring and this model also features a battery backup system so that the unit can still be monitored for up to 12 hours in the event of a power failure. The GSM Adaptor will work when connected to any 3-Pin  type socket with 220-250V Supply and where a 800/1900 MHz mobile phone network is available.
