Setting the AM tuning step frequency
(Worldwide models only)
Worldwide models are equipped with a switch that controls the AM
band tuning steps. Please set this switch to match the AM band tun-
ing step frequency in your area.
U.S.A. and Canada : 10 kHz
Other areas : 9 kHz
Setting the Voltage selector (Worldwide models
only)
Worldwide models are equipped with a voltage selector to conform with
local power supplies. Be sure to set this switch to match the voltage of
the power supply in your area before plugging in the unit.
1. Determine the proper voltage for your area: 220-230 V or
120 V.
2. If the preset voltage is not correct for your area, insert a screw-
driver into the groove in the switch. Slide the switch all the way
to the right (120 V) or to the left (220-230 V), whichever is
appropriate.
Installing the remote controller batteries
1. Remove the battery compartment cover by pressing the tab and
lifting up the cover.
2. Insert two AA (R6- or UM-3)-size batteries into the battery compart-
ment. Carefully follow the polarity diagram (positive (+) and nega-
tive (–) symbols) inside the battery compartment.
3. After batteries are installed and seated correctly, replace the com-
partment cover.
Notes
Do not mix new batteries with old batteries or different kinds of
batteries.
To avoid corrosion, remove the batteries if the remote controller
is not to be used for a long time.
Remove dead batteries immediately to avoid damage from cor-
rosion. If the remote controller doesn't operate smoothly,
replace both the batteries at the same time.
The life of the batteries supplied is about six months but this
will vary depending on usage.
Using the remote controller
Point the remote controller toward the remote control sensor.
The STANDBY indicator lights up when the unit receives a signal
from the remote controller.
Notes
Place the unit away from strong light such as direct sunlight or
inverted fluorescent light which can prevent proper operation of the
remote controller.
Using another remote controller of the same type in the same
room or using the unit near equipment which uses infrared rays
may cause operational interference.
Do not put any object such as a book on the remote controller.
The buttons of the remote controller may be pressed by mistake
and drain the batteries.
Make sure the audio rack doors do not have colored glass. Plac-
ing the unit behind such doors may prevent proper remote con-
troller operation.
If there is any obstacle between the remote controller and the
remote control sensor, the remote controller will not operate.
