Group Scanning

TocommenceGROUP SCANNING, select the GROUP SCAN mode by pressing the OS/GS button when in the OS mode, and select the SCAN mode by momentarily pressing the SCAN button.

The SUNDOWNER UH-O99will now scan the programmed channels, displaying each channel number and the PRIORITY channel number. Before it scans each

channel, it quickly "checks" the PRIORITY channel (set by the CHANNEL SELEC- TOR).

NOTE: 1. In the GS mode, the starting channel prior to GS Memory Scanning is always set as the Initial PRI Channel.

2.If the GROUP SCAN memory has not been programmed when the GROUP SCAN mode is selected and the SCAN button has been

pressed, the SUNDOWN ER UH-O99will emit an error tone.

3.The PRIORITY channel number can easily be read when necessary by:

(a)Simply turning the Squelch knob counter-clockwise until the squelch opens. After checking, return the Squelch knob to the previous position.

(b)Pressing the PRESS- TO-TALKbutton, the unit will transmit on the PRI channel and scanning will be cancelled. Press the SCAN button to resume scanning.

Receiving a Signal on a Group Scan Channel

If a signal is received on a programmed scan channel, the radio will 'lock'onto that channel provided there is no signal on the PRIORITYchannel.

When the receiver is 'locked'onto the scan channel, the LCD Channel Indicator will switch between the scan channel and the PRIORITY channel. This is because the

receiver is still 'listening'for signals on the PRIORITY channel.

When the scan channel becomes quiet again, the radio will continue to hold the channel for another 3 seconds in order to allow for a natural pause inthe conversation before resuming the Group Scanning mode.

If there is a transmission on the PRIORITY channel while you are listening to a scan channel, the receiver will immediately transfer to the PRIORITY channel and the PRIORITY channel number will be displayed.

To RESUME scanning, while receiving a signal, momentarily press the MEM button on the front panel. The receiver will resume scanning.

To stay on the current active channel, momentarily press the PTT button. The Scan Mode will be cleared.
