selected, a tone sounds and wrap-around to the highest system or group
occurs.
• 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. A leading “0” must be entered for digits 1-9
for the selected system or group to change.
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. To disable and enable the keypad, press FCN . The locked
condition is indicated by the icon. If a key is pressed with the keypad
locked, all that happens is “LOCKED” is displayed. The top and side
panel controls remain functional with this feature selected. Turning the
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. To unlock the transceiver, the four-digit pass-
word is re-entered.
When the transceiver is in the lock mode, calls cannot be received or
transmitted. In addition, all controls except the on-off/volume control are
disabled. 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.
