PRECAUTIONS
Read the Operating instructions carefully and completely before
operating the unit. Be sure to keep the Operating Instructions
for future reference. All warnings and cautions in the Operating
Instructions and on the unit should be strictly followed, as well
as the safety suggestions below.
Installation
1 Water and moisture — Do not use this unit near water, such
as near a bathtub, washbowl, swimming pool, or the like.
2 Heat — Do not use this unit near heat sources, including
heating vents, stoves, or other appliances that generate heat.
It also should not be placed in temperatures less than 5°C
(41°F) or higher than 35°C (95°F).
3 Mounting surface — Place the unit on a flat, even surface.
4 Ventilation — The unit should be situated with adequate
space around it so that proper heat ventilation is assured.
Allow 10 cm (4 in.) clearance from the rear and the top of the
unit, and 5 cm (2 in.) from each side.
- Do not place the unit on a bed, rug, or similar surface that
may block the ventilation openings.
- Do not install the unit in a bookcase, cabinet, or airtight rack
where ventilation may be impeded.
5 Objects and liquid entry — Take care that objects or liquids
do not get inside the unit through the ventilation openings.
6 Carts and stands — When placed or
mounted on a stand or cart, the unit
should be moved with care.
Quick stops, excessive force, and
uneven surfaces may cause the unit or
cart to overturn or fall. —
7 Wall or ceiling mounting — The unit should not be mounted
on a wall or ceiling, unless specified in the Operating
Instructions.
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 — Asa 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 is not still inserted easily 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 firmly secured 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
power 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 fiow to the unit, even when the power is turned
off.

Outdoor Antenna
1 Power lines — When connecting an outdoor antenna, make
sure it is located away from power lines.
2 Outdoor antenna grounding — Be sure the antenna system
is properly grounded to provide protection against unexpected
voltage surges or static electricity build-up. Article 810 of the
National Electrical Code, ANSI/NFPA70, provides information
on proper grounding of the mast, supporting structure, and
the lead-in wire to the antenna discharge unit, as well as the
size of the grounding unit, connection to grounding terminals,
and requirements for grounding terminals themselves.
