Important Safety Information
Verify Line Voltage before Use
the HK 3700/3770 has been designed for use with 100- 240 Volt alternating current
(ac). 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 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 the use of 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
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 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.
