This ultra-miniature GSM listening device really is quite incredible. A huge amount of technology packed into a tiny housing and because it is Quad band  it will work anywhere in  the world where there is GSM coverage.  The standard unit is only supplied with dual band 900 and 1800Mhz  but it can be supplied to work on 850 and 1900Mhz if required - PLEASE SPECIFY WHEN ORDERING. You can dial into it to listen from either a landline or a cellular phone.

The GSM400mini is only 43x34x17mm's making it small enough to be hidden almost anywhere in the home, office or car. It can even be hidden in a handbag or briefcase.

New filtering circuitry and a DSP (Digital Sound Processor)  means that you get the best possible sound quality, free of buzz and hum like so many of the cheaper units are plagued with.

One charge and this unit will be ready to give you up to 6 days on standby and 6 -8 hours of quality listening. For long term monitoring the unit can be permanently connected to the mains.

Supplied with  a charger and 3 different mains connectors

PLEASE REMEMBER THAT THIS STANDARD UNIT IS SUPPLIED ON 900 AND 1800MHZ FOR OPERATION IN EUROPE, ASIA, AFRICA, AUSTRALIA, ETC BUT IT CAN BE SUPPLIED ON 850 AND 1900MHZ FOR OPERATION IN THE US  - PLEASE SPECIFY WHEN ORDERING, IF REQUIRED.
