TA-388 Handheld

PTToC Push-to-Talk over Cellular (PoC) is a technology offering VoIP two-way radio communication over a Wide Area utilising the cellular phone data networks

The TA-388 handheld packs a big punch for a small radio. A large 5200mAh battery offers extended operational time well over 2 days*. Programmable function keys, colour TFT display and easy menu driven functionality make this unit a breeze to operate. The TA-388 also offers SOS emergency call and USB charging.

All ToooAir transceivers have built in GPS receivers that report position information to the dispatch console. The ToooAir platform is ideal for rental fleets with full over-air re-programming. With no ACMA spectrum licencing required, radios can be moved from fleet to fleet or new talk groups and operated anywhere in Australia.

* Distance to cellular tower, GPS reporting and talk time effect battery drain.
