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 sup-

ply 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 safe- ty feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fall 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. Nonuae Periods -- When the unit is not used, turn the power off. When left unused for a long 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 ground-

ed so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Elec-

trical 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 conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. See figure

below.

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 sub-

ject this unit to excessive smoke, dust, mechanical vibration,

or shock.

3. Magnetism -- The unit should be situated away from equip- ment or devices that generate strong magnetism,

4. Stacking -- Do not place heavy objects, other than system components, 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 com-

bination to overturn.

7. Wall or Ceiling Mounting -- The unit should not be mounted

to a wall or ceiling, unless specified in this operating instruc- tions.

Maintenance

Clean the cabinet, panel and controls with a soft cloth lightly

moistened with mild detergent solution.

Donot use anytypeof abrasivepad,scouringpowderor solvent

suchas alcoholor benzine.

Service

1. Damage Requiring Service -- The unit should be serviced by qualified service personnel when:

(a) The AC power supply cord or the plug has been damaged;

(b) Objects have fallen or liquid has been spilled into the unit;

marked change in performance; or

(e) The unit has been dropped, or the enclosure damaged.

Listening caution

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 equipment offers. This manufacturer and the Electronic In- dustries Association'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 an-

noying blaring or distortion-and, most importantly, without affec- ting 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 low 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.
