PMR446 handheld radio
The TC-446S licence-free radio combines
modern analogue technologies with user-friendly
design to boost your productivity.
Thanks to its compact form and light weight,
this robust two-way radio is ideally suited for
use in facility management, catering and
hospitality, production and manufacturing,
retail, education and construction.
Highlights
Licence-free two-way radio
The TC-446S is a PMR446 radio and can therefore be used straight out of the box
without the need to acquire a radio licence.
Longer battery life and energy-saving functions
With a standard battery the TC-446S achieves a battery life that can easily outlast a
shift, whilst the optional high capacity battery can last up to 24 hours from a single charge,
on 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 deliver 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.
