y When the alert is detected, a beep sounds and the follow-
ing indication will be displayed.
u 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 the case that the alert function is turned ON. This symp-
tom is caused by the WX alert function. To cancel these
symptoms, set the weather alert item OFF in set mode.
■ Power save
The power save function reduces the current drain to con-
serve battery power. 
The power save duty cycle, the ratio of receive circuit on to
receive circuit off while standing by, can be set to automatic
(default), 1 : 1 (150 msec. : 150msec.), 1 : 4 (150 msec. :
600msec.), 1 : 8 (150 msec. : 1200msec.) or OFF in POWER
SAVE set mode. (p. 
??
)
• “AUTO” selects “1 : 4” duty ratio when receiving no signal for 5 sec.,
then “1 : 8” 60 sec. after that.
When automatic is selected, the power save automatically
turns OFF while operating with an external DC power sup-
ply. (11.0 V DC ± 5 %)
