Factory Reset
If the radio’s display locks up or stops functioning properly, you might
need to reset your UHF radio.
Caution: This procedure clears all the information you have stored in
your UHF radio.
Before you reset your UHF radio, try turning it off and on again.
If your UHF radio is still not functioning correctly, you may need to reset
the UHF radio.
To reset, Press and Hold Monitor and power on. “Reset” will appear in
the display. The radio will then return to standby mode.
TOT (Time Out Timer)
Australian and New Zealand standards require that if the PTT is
pressed for more than 3 minutes the unit must stop transmitting. The
radio is set to stop transmitting after 2 minutes and 30 seconds of
continuous transmission. “TOT-on” will appear in the display and it will
emit a beep sound to indicate that TOT is activated.
