Battery Save
In Standby mode, if the radio is inactive (no key press/transmission/reception) for 10 seconds
(programmable), it will automatically enter Battery Save mode to reduce battery consumption. The radio
may exit the Battery Save mode and get activated once any key is pressed or any signal is received.
Busy Channel Lockout
If enabled via the programming software, this feature can prevent your radio interfering with other
transmitting radios on the same channel. If you hold down the
PTT
key while the channel is in use, your
radio will keep beeping and return to Receive mode. To stop beeping, please release the
PTT
key.
