TX3820BU UHF Modular Commercial Transceiver.
The GME Commercial Modular Series offers the end user greater flexibility when choosing a commercial radio.
It allows the end user to purchase a base radio and then choose between a 'Remote Head' or 'Remote LCD Microphone'.
There are also a variety of microphone options that can be used with the remote head.
The TX3820BW is a continued evolution of GME's TX3600 under dash series of UHF radios.
It represents a major advance in commercial radio with outstanding features, performance and flexibility.
With the option of adding the RH004 remote head and your choice of microphone, or you may choose the compact MC522BC remote LCD microphone
Installation is simple; with the radio measuring just 140mm (W) x 145mm (L) x 30mm (H) mm the TX3600 easily fits into the confines of modern vehicles.
The radio can be installed under the seat with the remote head or LCD mic option to be fitted to the centre console or dash.
