Before Using the AV Receiver
The Worldwide model has a voltage selector for compat-
ibility with power systems around the world. Before you
plug in this model, make sure that the voltage selector is
set to the correct voltage for your area. If it isn’t, use a
small screwdriver to set it as appropriate. For example, if
the voltage in your area is 120 volts, set the selector to
“120V.” If it’s between 220 and 230 volts, set it to “220-
230V.”
Notes:
• The batteries should last for about six months,
although this will vary with usage.
• If the remote controller doesn’t work reliably, try
replacing the batteries.
• Don’t mix new and old batteries or different types of
batteries.
• If you intend not to use the remote controller for a long
time, remove the batteries to prevent damage from
leakage or corrosion.
• Expired batteries should be removed as soon as possi-
ble to prevent damage from leakage or corrosion.
To use the remote controller, point it at the AV Receiver’s
remote control sensor, as shown below.
Notes:
• The remote controller may not work reliably if the AV
Receiver is subjected to bright light, such as direct
sunlight or inverter-type fluorescent lights. Keep this
in mind when installing.
• If another remote controller of the same type is used in
the same room, or the AV Receiver is installed close to
equipment that uses infrared rays, the remote control-
ler may not work reliably.
• Don’t put anything, such as a book, on the remote con-
troller, because the buttons may be pressed inadvert-
ently, thereby draining the batteries.
• The remote controller may not work reliably if the AV
Receiver is installed in a rack behind colored glass
doors. Keep this in mind when installing.
• The remote controller will not work if there’s an obsta-
cle between it and the AV Receiver’s remote control
sensor.
