The backlighting feature is used to improve
readability of the LCD display in dim light.
Using the Key Lock Feature
If you desire to maintain a selected function
on your VHF 720, such as TRI-WATCH, SCAN,
or Weather Alert, you can lock the keys using
the Lock feature to prevent inadvertent canceling
or changing of unit settings. However, the Press-
To-Talk, Squelch, and Power keys still function.
