connection to a line voltage other than that for which your receiver 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.

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 your receiver for any considerable length of time, 

disconnect the plug from the Ac outlet.

Do Not Open the Cabinet

the unit, disconnect it from the Ac power source immediately, and consult an authorized 

service center.

CATV or Antenna Grounding (AVR3700/AVR 2700)
If an outside antenna or cable system is connected to this product, be certain that it is 

grounded so as to provide some protection against voltage surges and static charges. 

Section 810 of the united States national electrical code, AnSI/nfpA no. 70-1984, 

provides information with respect to proper grounding of the mast and supporting 

structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding 

conductors, location of antenna discharge unit, connection to grounding electrodes and 

requirements of the grounding electrode.
note to cAtv SyStem InStAller: this reminder is provided to call the cAtv (cable tv) 

system installer’s attention to article 820-40 of the nec, which provides guidelines for 

proper grounding and, in particular, specifies that the cable ground shall be connected 

to the grounding system of the building, as close to the point of cable entry as possible.

•  place the receiver on a firm and level surface. be certain that the surface and any
