Call

Indicator

This indicator is turned off by pressing any button or cycling transceiver power. If scanning and the “Last Received” configura- tion is programmed (see “Transmitting In The Scan Mode” on page 39), the system and group of the last call are displayed. Other- wise, the currently selected system/group is displayed.

Emergency Switch

Encryption is enabled and disabled by the ENCRYPT menu parameter or ENCPT option switch (see page 33). If this menu
