BASIC OPERATION
D
D
Weather alert function
NOAA broadcast stations transmit weather alert tones before
important weather announcements. When the weather alert
function is turned ON, the selected weather channel is moni-
tored each 5 sec. for the announcement. When the alert sig-
nal is detected, the “ALt” and the WX channel are displayed
alternately and sounds a beep tone until the receiver controls
are manipulated. The previously selected weather channel is
checked periodically during standby or while scanning.
q
Select the desired weather channel.
w
Turn the weather alert function ON in set mode.
• Push [MAIN] to select the desired band (left or right) as the main
band in advance.
➥
Push [SET•SKIP] to enter set mode.
➥
Push [SET•SKIP] or [ATT•PRIO] to select the weather
alert item, then rotate the main band’s [DIAL] to set ON.
➥
Push any key for main band to exit set mode.
e
Select the desired stand-by condition.
• Select VFO or memory channel.
• Scan or priority watch operation can also be selected.
r
When the alert is detected, a beep sounds and the follow-
ing indication will be displayed.
t
Turn the weather alert function OFF in set mode.
NOTE: While receiving a signal (on a frequency other than
the weather alert ON frequency), the receiving signal or
audio will be interrupted momentarily every 5 sec.
(approx.)
in case the alert function is turned ON. This is caused by
the WX alert function. To eliminate the interruptions, set the
weather alert item OFF in set mode.
Shows above indications alternately.
