The transceiver has 2 scan modes: normal scan and priority
scan. Normal scan searches all tag channels in the selected
channel group. Priority scan searches all tag channels in se-
quence while monitoring channel 16.

The scan resume timer can be selected as a pause (OFF) or
timer scan (ON). When OFF is selected, the scan pauses
until the signal disappears. When ON is selected, the scan
pauses 5 sec. and resumes even if a signal is being received
on channels except for channel 16.

An NOAA broadcast station transmits a weather alert tone be-
fore important weather information. When the weather alert
function is turned ON, the transceiver detects the alert, then
flashes the “WX ALT” indicator until the transceiver is oper-
ated. The previously selected (used) weather channel is
checked any time during standby or while scanning.

• “WX ALT” appears instead of “WEATHER” indication when the func-

tion is set ON.

This item sets the [CH/WX•DW] switch function as dual watch
or tri-watch.

See the section ‘Dual watch/Tri-watch’ for details.
