Memory Preservation
This unit does not require memory preservation
batteries. A built-in memory power back-up sys-
tem preserves the contents of the memory dur-
ing power failures and even when the unit is un-
plugged. The unit must be plugged in order to
charge the back-up system.
The memory preservation period after the unit
has been unplugged varies depending on climate
and placement of the unit. On the average,
memory contents are protected over a period of
a few weeks after the last time the unit has been
unplugged. This period is shorter when the unit
is exposed to a highly humid climate.

Important Safeguards
10. Power Sources The appliance should be
connected to a power supply only of the type
described in the operating instructions or as
marked on the appliance.
11. Polarization If the appliance is provided with
a polarized plug having one blade wider than
the other, please read the following information:
The polarization of the plug is a safety feature.
The polarized plug will only fit the outlet one
way. If the plug does not fit fully into the out-
let, try reversing it. If there is still trouble, the
user should seek the services of a qualified elec-
trician. Under no circumstances should the user
attempt to defeat the polarization of the plug.
12. Power-Cord Protection Power-supply
cords should be routed so that they are not
likely to be walked on or pinched by items
placed upon or against them, especially near
plugs, convenience receptacles, and the
point where they exit from the appliance.
13. Cleaning The appliance should be cleaned
only as recommended by the manufacturer.
14. Nonuse Periods The power cord of the ap-
pliance should be unplugged from the outlet
when left unused for a long period of time.
15. Object and Liquid Entry Care should be taken
so that objects do not fall and liquids are not spilled
into the enclosure through openings.
16. Damage Requiring Service The appliance
should be serviced by qualified service per-
sonnel when:
A. The power-supply cord or the plug has
been damaged; or
B. Objects have fallen, or liquid has been
spilled into the appliance; or
C. The appliance has been exposed to rain; or
D. The appliance does not appear to oper-
ate normally or exhibits a marked change
in performance; or
E. The appliance has been dropped, or the
enclosure damaged.
17. Servicing The user should not attempt to ser-
vice the appliance beyond that described in the
operating instructions. All other servicing should
be referred to qualified service personnel.
1.
Read Instructions All the safety and
operating instructions should be read before
the appliance is operated.
2.
Retain Instructions The safety and

Carts and Stands The appliance should
be used only with a cart or stand that is rec-
ommended by the manufacturer.

combination to over-
turn.
7.
Wall or Ceiling Mounting The appliance
should be mounted to a wall or ceiling only
as recommended by the manufacturer.
8.
Ventilation The appliance should be situ-
ated so that its location or position does not
interfere with its proper ventilation. For ex-
ample, the appliance should not be situated
on a bed, sofa, rug, or similar surface that
may block the ventilation openings; or if
placed in a built-in installation, such as a
bookcase or cabinet that may impede the
flow of air through the ventilation openings,
there should be free space of at least 20 cm
(8 in.) and an opening behind the appliance.
9.
