IMPORTANT SAFETY INSTRUCTIONS
Read these operating instructions carefully before using the unit. Follow the safety instructions on the unit and the safety
precautions listed below. Keep these operating instructions handy for future reference.
Safety
1. Power source—Connect the
unit to a power source of the type
described in these instructions or
as marked on the unit.
2. Polarization—The unit is
equipped with a polarized power
plug where one blade is wider
than the other. This safety fea-
ture ensures that the plug fits into
your household AC outlet only
one way. If the plug doesn’t fit
one way, try reversing it. If the
plug still doesn’t fit, contact an
electrician to replace the obso-
lete outlet. Do not attempt to
defeat the safety purpose of the
plug.
3. Power cord protection—Route
the AC power supply cord so that
it will not be walked on or pinched
by items placed on or against it.
Never take hold of the plug or
cord with wet hands. Always
grasp the plug body firmly when
connecting and disconnecting it.
4. Overloading—When connect-
ing the AC power supply cord, be
careful not to overload the
household AC outlet, extension
cord, or outlet from any other
device as this can result in fire or
electric shock.
5. Nonuse periods—Turn the unit
off when it is not in use. Unplug
the unit from the household AC
outlet if it is not to be used for a
long time. Unplug the unit during
lightning storms. Leaving the unit
connected to a household AC
outlet for extended periods can
cause battery fluid leakage.
6. Attachments and accesso-
ries—Use only the attachments
and accessories recommended
in these operating instructions.

jects and liquids do not get into

es that generate strong magnetic

from heat sources, such as radia-
tors. Do not leave it in an auto-

tures fall below 5oC (41oF) or rise
