Important Safety Information

Verify Line Voltage before Use

The HK 3700/3770 stereo receiver has two different models. One model is 120 V with a

fixed power cord and another is 220 -240 V with a detachable power cord. Connection

to a line voltage other than that for which your HK 3700/3770 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 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 using extension cords with this product. 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

To disconnect the power cord from an AC outlet, always pull the plug; never pull the

cord. If you do not intend to use your HK 3700/3770 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.

CATV or Antenna Grounding

If an outside antenna or cable system is connected to this product, be certain that it

is grounded to provide 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.

Placing the Stereo Receiver

• Place the stereo receiver on a firm and level surface. Be certain that the

surface and any mounting hardware can support the stereo receiver’s

weight.

• Provide proper space above, below, behind and to the sides of the stereo

receiver for ventilation. Maintain a clearance of at least 12” (30 cm) on each

side, above and behind the unit.

• If you install the stereo receiver in a cabinet or other enclosed area, provide

cooling air within the cabinet. Under some circumstances, you may require

a fan.

• Do not obstruct the ventilation slots on the top of the stereo receiver or

place objects directly over them.

• Do not place the stereo receiver directly on a carpeted surface.

• Do not place the stereo receiver in moist or humid locations, in extremely

hot or cold locations, in areas near heaters or heat registers, or in direct

sunlight.
