The front panel panel controls can be “LOCKED” to
prevent accidental changes being made during operation
and handling.

To LOCK the UCR511 - Press and hold the MENU
button until a bar tracks horizontally across the LCD
screen and the word “LOCKED” appears. If the MENU
button is released before the word “LOCKED” appears,
the unit will remain UNLOCKED. When in a LOCKED
state, the pilot tone bypass toggle is also defeated.

In LOCKED state, the use of the MENU and SEL Up/
Down buttons are limited to “view only” and any attempts
to change selections will result in a LCD screen display
ing the word “LOCKED.” The unit cannot be used for RF
scanning when it is set in the LOCKED state.

To UNLOCK the UCR511 - Press and hold the MENU
button until a bar tracks horizontally across the screen
and the word “UNLOCKED” is displayed on the LCD
screen. When the unit is UNLOCKED, all settings can be
altered.

The UCR511 can only be LOCKED or UNLOCKED from
any of the main windows. (There are four of them.)
Also, it cannot be switched between LOCKED and
UNLOCKED modes when it is in a scanning mode or
from other subordinate screens.
