This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.

This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

-Reorient or relocate the receiving antenna.

-Increase the separation between the equipment and receiver.

-Connect the equipment into an outlet on circuit different from that to which the receiver is connected.

-Consult the dealer or an experienced radio/TV technician for help.

CAUTION

Modifications or adjustments to this product, which are not expressly approved by the manufacturer, may void the user’s right or authority to operate this product.

PRECAUTIONS

2Heat — 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 5°C (41‘F) or greater than 35°C (95”F).

3Mounting surface — Place the unit on a flat, even surface.

4Ventilation — 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.

-‘Donot 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,

m

AA* 3

and uneven surfaces may cause

 

 

the unit orcartto overturn or fall.

 

 

7Condensation — 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.

8Wall or ceiling mounting —Theunit should not be mounted on a wall or ceiling, unless specified in the Operating Instructions.

Electric Power

1Power sources — Connect this unit only to power sources specified in the Operating Instructions, and as marked on the unit.

2Polarization — 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 inserl 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.

3AC 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 power plugs and extension cords beyond their capacity, as this could result in fire or shock,

1 ENGLISH

4Extension 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.

5When not in use — Unplug the AC power cord from 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

1Power lines — When connecting an outdoor antenna, make sure it is located away from power lines.

2Outdoor 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, AN S1/NFPA70, provides information

on proper grounding of the mast, supporting structure, and the lead-inwire to the antenna discharge unit, as well as the size of the grounding unit, connection to grounding terminals, and requirements for grounding terminals themselves,
