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-

power) key for more than one second after you

have set the unit to the function desired. When

the unit keypad is locked, the LOCK message

will be displayed on the LCD screen. (Figure 12)

2. To cancel the lock feature, press the H/L-LOCK

key again for more than one second or turn Off
