Precautions

Before using this unit please read these operating instructions carefully. 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 polarized plug.

3.Power Cord Protection—AC 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. 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 tong period of time, the unit should be unplugged 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 re­ spect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. See figure below.

2.Water and Moisture—Do not use this unit near water—for ex­ ample, near a bathtub, washbowl, swimming pool, or the like. Damp basements should also be avoided.

3.Heat—The unit should be situated away from heat sources such as radiators and the like.

It also should not be placed in temperatures less than S^C {41”F) or greater than 35“C (95“F).

4.Condensation—Moisture may form on the lens in the following conditions...

•immediately after a heater has been turned on.

•in a steamy or very humid room.

•when 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 position does not interfere with its proper ventilation. Allow 10 cm (4") 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. Magnetism—The unit should be situated away from equipment or devices that generate strong magnetic fields.

Stacking—Do not place heavy objects, other than system com­ ponents, on top of the unit.

Surface—Place the unit on a flat, level surface.

Carts and Stands—The unit should be used only with a cart or stand that is recommended by the manufacturer.

Concerning the remote control

Listening caution		^BOttieiy ^ih sta I Iqtid^

Selecting fine audio equipment such as the unit you've just pur­ chased is only the start of your musical enjoyment. Now it's time to consider how you can maximize the fun and excitement your equip­ ment offers. This manufacturer and the Electronic Industries Associ­ ation's Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion—and, most importantly, without affecting your sensitive hearing.

We recommend you to avoid prolonged exposure to excessive noise.

Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of sound. So what sounds "normal” can actually be loud and harmful to your hearing.

Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.

To establish a safe level:

•Start your volume control at a tow setting.

•Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.

Once you have established a comfortable sound level:

•Set the dial and leave it there.

Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime.
