Important Safety InformatIon
Verify Line Voltage Before use
Your AVR 760/AVR 660 has been designed for use with 230-240 volt AC
current. Connection to a line voltage other than that for which it is intended
can create a safety and fire hazard and may damage the unit.
If you have any questions about the voltage requirements for your specific
model, or about the line voltage in your area, contact your selling dealer
before plugging the unit into a wall outlet.
Do not use extension cords
To avoid safety hazards, use only the power cord supplied with your unit. We
do not recommend that extension cords be used with this product. As with all
electrical devices, do not run power cords under rugs or carpets or place heavy
objects on them. Damaged power cords should be replaced immediately by
an authorized service center with a cord meeting factory specifications.
Handle the ac power cord Gently
When disconnecting the power cord from an AC outlet, always pull the plug;
never pull the cord. If you do not intend to use the unit for any considerable
length of time, disconnect the plug from the AC outlet.
Do not open the cabinet
There are no user-serviceable components inside this product. Opening the
cabinet may present a shock hazard, and any modification to the product will
void your warranty. If water or any metal object such as a paper clip, wire
or staple accidentally falls inside the unit, disconnect it from the AC power
source immediately, and consult an authorized service center.
