Your HK 3370 has been designed for use with
120-volt AC current. Connection to a line volt-
age other than that for which it is intended can
create a safety and fire hazard, and may dam-
age 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 sell-
ing dealer before plugging the unit into a wall
outlet.
Do Not Use Extension Cords
To avoid safety hazards, use only the power
cord attached to your unit. We do not recom-
mend 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 with cords
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.
