Safety Instructions
For safe operation, always follow the guidelines provided for the Harman Kardon AVR 3700 Audio-Video Receiver.
Verify Line Voltage Before Use
- The AVR 3700 and AVR 2700 have been designed for use with 120-volt AC.
- The AVR 370 and AVR 270 have been designed for use with 220 – 240-volt AC. 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.
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
For optimal safety and longevity, make sure the Harman Kardon AVR 3700 Audio-Video Receiver is powered off before handling the AC power cord.
- 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
- 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.
Antenna Grounding
- 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.
- 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.
