TC-446S License-free PMR446 handheld radio
The unlicensed TC-446S radio unit combines modern analog technologies with a user-friendly design, thus allowing you to increase productivity.
Thanks to its compact design and low weight, this rugged radio is ideal for use in facility management, hospitality, manufacturing, retail, education and construction.
Salient features
- The TC-446S is a PMR446 radio device and can therefore be used without special permits or licenses.
Long battery life and power saving features
- The TC-446S, with its standard battery, achieves an operating life of up to 24 hours, with an operating cycle of 5-5-90. The programmable energy saving function is activated when the appliance has not been in operation for more than 10 seconds.
CTCSS / CDCSS signal
- 38 different CTCSS sub-tones and 61 different CDCSS tones allow you to make direct calls, group calls and remote commands quickly and comfortably.
Transmission time limitation
- The TC-446S has a transmission time limitation to prevent it from running for a long time by mistake.
