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 sources of heat, including heating vents, stoves, or other appliances that generate
heat. It also should not be placed in temperatures less than 5ºC (41ºF) or greater than 35 Cº(95ºF).
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 then tope 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 of 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 Condensation - Moisture may form on the CD pickup lens when:
- The unit is moved from a cold spot to a warm spot
- The heating system has just been turned on
- The unit is used in a very humid room
- The unit is cooled by an air conditioner
When this unit has condensation inside, it may not function normally. Should this occur, leave the unit for a few
hours, then try to operate again.
8 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 - 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 power plugs and extension cords beyond their capacity, as this could result in fire or shock.
PRECAUTIONS (cont.)
pg. 2
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 form the AC power plug 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, 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/NFPA 70,
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.
Maintenance
Clean the unit only as recommended in the Operating Instructions
