ELECTRIC POWER
1 Power Sources - Connect this unit only to power sources specified in
the Operating Instructions, and as marked on the unit.
2 Polarization - As a safety feature, some units are equipped with
polarized AC power plugs which can only be inserted one way into a
power outlet. If it is difficult or impossible to insert the AC power plug
into an outlet, turn the plug over and try again. If it still does not easily
insert into the outlet, please call a qualified service technician to service
or replace the outlet. To avoid defeating the safety feature of the
polarized plug, do not force it into a power outlet.
3 AC power cord - When disconnecting the AC power cord, pull it out
by the AC power plug. Do not pull the cord itself.
• Never handle the AC power plug with wet hands, as this could result
in fire or shock.
• Power cords should be routed to avoid being severely bent, pinched,
or walked upon. Pay particular attention to the cord from the unit to
the power socket.
• Avoid overloading AC outlets and extension cords beyond their
capacity, as this could result in fire or shock.
4 Extension cord - To help prevent electric shock, do not use a polarized
AC power plug with an extension cord, receptacle, or other outlet
unless the polarized plug can be completely inserted to prevent
exposure of the blades of the plug.
5 When not in use - Unplug the AC power cord from the AC outlet if
the unit will not be used for several months or more. When the cord is
plugged in, a small amount of current continues to flow to the unit,
