5.8 PROGRAMMABLE PRIORITY SCAN

The priority scanning feature allows the radio to scan while also keeping watch on a particularly important “priority channel.” The following channels can be set as the priority channel: 16, 09, and Preset Channels 1 through 8 (Preset Channels are described in section 5.14).

1.To set the priority channel, hold down the 16/9 key and press the MEM key. The channel will change from 16 to 09 to Preset 1 to Preset 2 to Preset 3 to Preset 4 to Preset 5 to Preset 6 to Preset 7 to Preset 8 with each press of the MEM key. The displayed channel will be set as the priority channel when the 16/9 key is released.

2.For priority scanning, hold down the SCAN key during normal scanning. Scanning will proceed between the memorized channels and the priority channel. The priority channel will be scanned after each programmed channel. “P” is shown on the left side of the channel number during pri- ority scanning.

3.As an example of priority scanning, let us say that channels 06, 07, and 08 are memorized in the transceiver’s scan memory. Priority scanning will proceed in the following sequence:

[CH06]  [Priority Channel]  [CH07]  [Priority Channel] 

[CH08]  [Priority Channel]  [CH06]  [Priority Channel] ……

4.Even when the transceiver stops and listens to the signal of a programmed channel, the transceiver will “dual watch” between this channel and the priority channel. Therefore, your priority watching of the designated chan- nel is not compromised when the scanner has paused on an active channel.

5.9 DUAL WATCH

The Dual Watch feature allows the radio to watch for a transmission on the priority channel and another selected Marine channel until a signal is re- ceived. The priority channel is determined per the discussion in section 5.8 “PROGRAMMABLE PRIORITY SCAN” as described previously.

1.To start the Dual Watch feature, select a channel to be dual watched with the priority channel and press and hold in the

SCAN key. The radio checks the priority channel for voice traffic every one second. A small “DW” icon will be shown blinking on the left of the display during scanning.

2.To cancel the Dual Watch feature, press the SCAN key.
