Hytera TC-446S Analogue PMR446 Radio

The licence free radio TC-446S combines modern analogue technologies with user friendly design and therefore boosts productivity. Thanks to it's compact design and lightweight, this robust two way radio is ideally suited for use in facility management.

Licence free two way radio
The TC-446S is a PMR446 radio and can therefore be used without any specific proof of necessity or a licence

Long battery service life and energy saving functions
With its standard battery the TC-446S achieves in operation a service life of up to 24 hours with a duty cycle of 5-5-90. The programmable energy-saving function activates itself if the two-way radio has not been used for 10 seconds.

CTCSS/CDCSS signaling
38 different CTCSS and 61 different CDCSS sub-audio tones allow a quick and user-friendly direct call, group call and remote control.

Time-out timer
The TC-446S features a time-out timer to avoid inadvertent continuous operation.
