License-free two-way radio

The TC-446S is a PMR446 radio and can therefore be used without any specific proof of necessity or a license.

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.
