Precautions - Panasonic SC-HT290 Operating Instructions Manual

PRECAUTIONS

Before using this unit please read these operating instructions care-
fully. Take special care to follow the warnings indicated on the unit
itself as well as the safety suggestions listed below.
Afterwards keep them handy for future reference.
Safety
1. Power Source—The unit should be connected to power supply
only of the type described in the operating instructions or as
marked on the unit.
2. Polarization—If the unit is equipped with a polarized AC power
plug (a plug having one blade wider than the other), that plug will fit
into the AC outlet only one way. This is a safety feature. If you are
unable to insert the plug fully into the outlet, try reversing the plug. If
the plug should still fail to fit, contact your electrician to replace
your obsolete outlet. Do not defeat the safety purpose of the polar-
ized plug.
3. Power Cord Protection—AC power supply cords should be rout-
ed so that they are not likely to be walked on or pinched by items
placed upon or against them. Never take hold of the plug or cord if
your hand is wet, and always grasp the plug body when connecting
or disconnecting it.
4. Nonuse Periods—When the unit is not used, turn the power off.
When left unused for a long period of time, the unit should be un-
plugged from the household AC outlet.
Installation
Environment
1. Outdoor Antenna Grounding—If an outside antenna is con-
nected to the receiver, be sure the antenna system is grounded so
as to provide some protection against voltage surges and built-up
static charges. Section 810 of the National Electrical Code, ANSI/
NFPA No. 70–1990, provides information with respect to proper
grounding of the mast and supporting structure, grounding of the
lead-in wire to an antenna discharge unit, size of grounding con-
ductors, location of antenna-discharge unit, connection to ground-
ing electrodes, and requirements for the grounding electrode. See
figure below.

as radiators and the like.
It also should not be placed in temperatures less than 5 oC (41 oF)
or greater than 35 oC (95 oF).
4. Condensation—Moisture may form on the lens in the following
conditions...
³immediately after a heater has been turned on.
³in a steamy or very humid room.
³when the unit is suddenly moved from a cold environment to a
warm one.
If moisture forms inside this unit, it may not operate properly. To
correct this problem, turn on the power and wait about one hour for
the moisture to evaporate.
Placement
1. Ventilation—The unit should be situated so that its location or po-
sition does not interfere with its proper ventilation. Allow
10 cm (4q) clearance from the rear of the unit.
2. Foreign Material—Care should be taken so that objects do not fall
into and liquids are not spilled into the unit. Do not subject this unit
to excessive smoke, dust, mechanical vibration, or shock.

devices that generate strong magnetic fields.
4. Stacking—Do not place heavy objects, other than system com-
ponents, on top of the unit.
5. Surface—Place the unit on a flat, level surface.
6. Carts and Stands—The unit should be used only with a cart or
stand that is recommended by the manufacturer. The unit and cart
combination should be moved with care. Quick
stops, excessive force, and uneven surfaces may
cause the unit and cart combination to overturn.
7. Wall or Ceiling Mounting—The unit should not
be mounted to a wall or ceiling, unless specified in
these operating instructions.
