BASIC OPERATION

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.
