3: Radio Operation
Key Lock Feature
The key lock feature prevents the accidental pressing of radio buttons
with the exception of
PTT and MONITOR.
To activate this feature:
1. Press
MONITOR for more than 2 seconds. Doing so displays the key
icon .
The key lock status is retained when the radio is turned off.
2. Release the key lock by pressing
MONITOR again for more than 2
seconds. The key icon is no longer displayed.
Power Save Feature
If no transmission or reception has occurred for 5 seconds, the receiver
switches from continuously on to periodically turning on and off based
on whether and how the radio is programmed. By reducing the amount
of time the receiver is on, battery life is extended.
The power save feature is set by the Programmer as follows.
•Battery Save On Timer:
Set to Disable or 200 ms to 1000 ms, at 50 ms increments
• Battery Save Off Timer:
Set to 100 ms to 500 ms, at 50 ms increments.
With this feature enabled, up to 500 ms of an incoming message can be
missed so in some cases the sender may have to repeat the call. However,
the resulting increase in battery life is usually worth this inconvenience.
