Installing the remote controller batteries
1. Remove the battery compartment cover by
pressing and sliding the cover.
2. Insert two AA (R6 or UM-3) batteries into the
battery compartment. Carefully follow the
polarity diagram (positive (+) and negative (–)
symbols) inside the battery compartment.
3. After batteries are installed and seated
correctly, replace the compartment 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
corrosion. If the remote controller does not 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 objects on the remote controller. Its buttons may be
pressed by mistake and drain the batteries.
• Make sure the audio rack doors do not have colored glass.
Placing the unit behind such doors may prevent proper remote
controller operation.
• If there is any obstacle between the remote controller and the
remote control sensor, the remote controller will not operate.

AM FREQUENCY STEP
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 tuning 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.
Determine the proper voltage for your area: 220-230 V or 120 V.
If the preset voltage is not correct for your area, insert a screwdriver
into the groove in the switch. Slide the switch all the way to the upper
(120 V) or to the lower (220-230 V), whichever is appropriate.
