BASIC OPERATION
22
• To directly select a system or group number, press SYS or GRP and
then the number of the desired system or group. For example, to select
Group 9, press GRP, 0, 9 (two digits must also be entered for numbers
0-9).
Keypad Disable
Occasionally, the front panel keys may be accidentally pressed, for
example, if you carry the transceiver on your belt and it brushes against
an object. To prevent this from happening, the front panel keys can be
disabled by the keypad lock feature. To lock and unlock the keypad, press
FCN . The locked condition is indicated by the icon and LOCK in
the display. If a key is pressed with the keypad locked, all that happens is
“LOCKED” is displayed. The top and side panel controls remain func-
tional with this feature selected, and turning power off and then on again
does not unlock the keypad.
Transceiver Lock
The transceiver can be locked to prevent unauthorized usage. To
lock the transceiver, press FCN and “PASSWORD” is then displayed
to indicate that a four-digit unlock password must be entered. This pass-
word can be any four-digit number except “0000”. The password must be
re-entered to confirm it and the transceiver is then locked as indicated by
“LOCKED” in the display.
When the transceiver is in the lock mode, calls cannot be received or
transmitted. In addition, all controls except FCN and the on-off/
volume control are disabled. To unlock the transceiver, the four-digit
password must be re-entered. The transceiver then remains unlocked until
it is locked again by repeating this sequence.
Since the password is not preprogrammed, a different password can
be entered each time this feature is used. If the password is forgotten, the
transceiver must be returned to your system operator for reprogramming
to make it operational again.
