■ Weather channel operation
(USA version only)
DD
Weather channel selection
q Push the desired band’s [M/CALL•MW] several times to
select weather channel group.
w Rotate the same band’s [DIAL] to select the desired
weather channel.
e Push the [M/CALL•MW] to select memory mode, or push
the [V/MHz•SCAN] to select VFO mode.
DD
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 “AL.t” and the WX channel are displayed
alternately and sounds a beep tone until the transceiver is op-
erated. The previously selected (used) 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
[SET• ]
to enter set mode.
➥ Push
[SET• ]
or [LOW•PRIO] to select the weather
alert item, then rotate the [DIAL] to set ON.
➥ Push [TONE•DTMF] to exit set mode.
e Sets the desired stand-by condition.
• Selects VFO, memory or call 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 symptom is
caused by the WX alert function. To cancel these symp-
toms, set the weather alert item OFF in set mode.
