License-free PMR446 frequencies
No subscription or call charges required to operate on PMR446 unlicensed frequencies, with 8 communication channels and user selectable PL codes to help ensure a clear signal.

Long Battery Life
The 1700mAh high capacity Li-ion battery can secure a battery life up to 10 hours.

Audio Compander
With advanced audio compander technology, TC-320 can ensure users quality communication in noisy environments.

Scrambler
This function is used for audio encryption, which can further secure the safety of communication, and those radios without this function are unable to receive real audio.

VOX Earpiece
If VOX (Voice-Operated Transmit) is programmed in your radio, you can communicate through your VOX earpiece to enjoy hands-free operation.
Battery Strength Indicator

High/Low Power Switchable

For each channel, the power can be adjusted through the key pre-set as High/Low power switch. When the communication range is small, low power is of priority for battery saving

Channel Scan
When scan is enabled, press the side key to start quick scan for all the channels in the scan list. The scan will stop or pause at the channel where a signal is detected.

Auto Battery Save
Radio enters “Battery Save” mode when no signal is received or there is no operation on the radio. This can prolong the battery life through lowering the battery consumption.

Low Battery Alert
Radio will alert users to charge the battery when it runs low.

Busy Channel Lockout(BCL)
BCL can prevent radio from receiving any unconfirmed signal and transmitting signal to any busy channel, keeping the channel clean and free of interference.

Time-out-timer (TOT)
This function is used to avoid time-out occupation of a channel. TOT restricts the maximum duration of each transmission, which not only can realize battery save and reduce the channel block time, but also can avoid the probability of channel occupation because of improper operations.

PC Programmable
This function enables users to program the radio’s frequency and other function settings without disassembling it.

Wired Clone
Users can clone the function parameter of a radio to another radio through the clone cable, requiring no PC programming operation.
