LOCKING AND UNLOCKING THE UCR211
FRONT PANEL CONTROLS
The front panel panel controls can be “LOCKED” to
prevent accidental changes being made during operation
and handling.
To LOCK - 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 SELECT
Up/Down buttons are limited to “view only” and attempts
to change selections will result in a screen displaying the
word “LOCKED.” The unit cannot be used for RF scan­
ning when it is set in the LOCKED state.
To UNLOCK - Press and hold the MENU button until a
bar tracks horizontally across the screen and the word
“UNLOCKED” appears. When the unit is UNLOCKED, all
settings can be altered.
The receiver can be LOCKED or UNLOCKED from any
of the four primary windows. It cannot be LOCKED from
the scanning mode or from other subordinate screens.
