Dual Watch, Scanning | Furuno FM-8700 manual

1.11 Dual Watch

The dual watch function permits watch on CH16 and another se- lected channel. CH16 and another channel are watched at intervals of 0.15 seconds and one second, respectively.

To start DW, first select the other frequency to watch and then press the SQUELCH control. When the receiver finds a signal on CH16, it locks on it and restarts dual watching after the signal on CH16 has gone. If another channel has traffic, it still continues dual watch. The speech is heard intermittently. If you are annoyed with the intermittence, turn off DW by pressing the PTT switch on the handset or pressing the SQUELCH control.

1.12 Scanning

The receiver scans all channels in the selected channel mode in ascending channel order, watching CH16 between channels as be- low:

1 16 2 16 3 16 4…

16 88 16 87 16 86 16…

To start scanning, press the SQUELCH control. When the receiver finds a signal, scanning is stopped on that channel and starts dual watch on it and CH16.
