[L/O] KEY
Press [L/O] to "lock out" or prevent scanning of
the displayed frequency. [L/O] is active only dur-
ing opened squelch or in the Hold Mode.
Locked out channel can be displayed on the
screen by using the [UP] or [DOWN] key to
manually scan through the selected bank in Hold
Mode only. "L/O" appears on the display to indi-
cate that the channel is locked out. Note: Lock-
ing out a channel will not erase the programmed
frequency.
[BAND] KEY
This key is active in Search Mode only (when
"SRCH" is displayed on the screen). When you
press [BAND], the upper and lower limits of the
band you are searching are displayed for 3 sec-
onds. Then the display returns to the current fre-
quency. Press [BAND] again within 3 seconds
to step up one higher band. Press this key as
many as it takes to find the band you want to be
searched.
Important: This key has a very important secon-
dary function. In Program Mode, you can press
[BAND] to leave this mode.
[PROG] KEY
This key initiates and completes programming.
It is active whenever a steady frequency appears
on the display. Press [PROG] to start Program-
ming Mode. "CH" appears and blinks, indicating
you are in Programming Mode, and urges you to
select the channel of the bank to be pro-
grammed. Press a programmable bank key
([PRIVATE], [FIRE/EMG] or [POLICE]) to be
programmed. Note: Never press non-program-
mable bank keys ([WX], [AIR] or [MRN]). If you
press one of these keys, "Error" will be dis-
played, and you may lose the frequency you
wanted to program.
