OUTDOOR ANTENNA GROUNDING If an outside an-

tenna is connected to the antenna terminal, be sure

the antenna system is grounded so as to provide

some protection against voltage surges and built

up static charges.

In the U.S.A, section 810 of the National Electrical

Code, ANSI/NFPA No. 70-1984, provides informa-

tion 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 require-

ments for the grounding electrode. See Fig. A.

CART -An appliance and cart combination should be

moved with care. Quick stops, excessive force, and

uneven surfaces may cause the appliance and cart

combination to overturn.

CHANNEL STEP SWITCH

(Multi-voltage model only)

The unit has been factory preset to the channel allocation and

deemphasis value for the area in which it is to be sold. If these

values are set incorrectly, the frequency display may stop at the

wrong frequency, or sound may be distorted, resulting in an inabil-

ity to reproduce reception signals at their proper sound quality.

For this reason, be sure to confirm that the values are set correct-

ly before first using the unit.

[100 kHz/10 kHz] position:

Set to this position for areas with an FM reception step of 100

kHz, AM 10 kHz.

[50 kHz/9 kHz] position:

Set to this position, for areas with an FM reception step of 50

kHz, AM 9 kHz.

NOTE:

When unsure about the channel a//ocation and de-emphasis

va/ues for your area, consult your dea/er for correct information.

Setting up the AM Antenna

• Insert the claw on the bottom of the antenna into the hole in

the leg.

•Place the antenna on a level surface and rotate it to locate the

orientation that yields the best reception.

•Use th_ attachment hole in the leg to screw to wall or other lo-

cation, then insert the claw on the bottom of the antenna into

the hole in the leg (fixing the antenna in the direction that

gives the best reception).

,_ Lead wire (_ Leg (_) Lead wire

NOTE FOR FM ANTENNA:

Stretch the antenna out to its full length, and affix it to a wall, etc.

NOTE FOR AM LOOP ANTENNA:

The antenna should be placed at a distance from the receiver, and

should not be allowed to touch metallic objects.

A void placing it near CD players, personal computers, television

sets, and other devices generating radio frequencies.

EXTERNAL FM ANTENNA

The main advantage of FM over AM is the quality of the broad-

cast signal. In order to benefit fully from the high signal quality of

FM broadcasts, it is recommended that a special-purpose FM an-

tenna be installed. In weak signal areas, a multi-element (3 ele-

ment, 5 element, 7 element, etc.) antenna should be used.

FM OUTDOOR ANTENNA CONNECTIONS

There are two ways of connecting the FM antenna to the antenna

input terminals: with a 300 _t twin-lead feeder or with a 75

coaxial cable.

To get the most from the receiver performance, a 75 _coaxial ca-

ble is recommended since it is more immune than the twin-lead

feeder to noise and interference from external sources. If an FM

antenna has already been erected outdoors, connect it, referring

to the figure.

GROUNDING

Grounding is recommended if reception of FM programs is im-

paired by noise. To ground, connect a thick polyvinyl insulated

wire to the GND terminal and attach the other end to a metal

water pipe or grounding bar or wind it around a copper plate and

bury it.

NOTE:

Never connect a wire to a gas pipe for grounding since sparks

may ignite the gas.

EXTERNAL AM ANTENNA

If it is not possible to obtain adequate AM reception even by

changing the orientation of the AM loop antenna, a separate in-

door antenna, or an outdoor antenna should be installed.

INDOOR AM ANTENNA

Use a polyvinyl insulated wire (5 - 6m:17 - 20 feet) and con-

nect one end to the AM antenna terminal and affix the other end

to the wall or ceiling, as high as possible.

OUTDOOR AM ANTENNA

If reception quality is not improved sufficiently even when an in-

door antenna is used, a polyvinyl insulated wire should be in-

stalled outside and fixed in place.

NOTE:

Do not detach the AM loop antenna when using an indoor or an

outdoor AM antenna.

it. The tuner will automatically search for a broadcasting station

and stop when one is found.

To search for another station, press again.

[High speed manual tuning]

Keep TUNING buttons pressed. The frequency changes continu-

ously, and stops when the button is released.

NOTE:

The TUNED indicator wil/ not function for broadcasts received

over/ong distances or when signa/s are weak.

4. Adjust the volume with the VOLUME control and

the tone with TREBLE tone control, BASS tone

control and S.BASS button.

When Receiving FM Broadcasts:

• If there is too much noise during reception of an FM stereo

broadcast, press the MPX MODE selector button to light the

MONO indicator. Switching to monaural reception results in

clear reception.

Note on Auto Tuning

•Because of high sensitivity of this unit, it may automatically

stop even at very weak overseas stations. The same can hap-

pen with aggregate radio noise emitted in cities.

• During reception of an AM broadcast, if it frequently stops

when presetting stations with auto tuning, auto tuning of only

strong local stations is possible by changing the direction of

the loop antenna or folding it down.

After presetting, move the loop antenna back to the position

where it is pointing in the best direction as before.

•Preset extremely weak stations with maunal tuning.

The TUNED Indicator

When the TUNED indicator is not lit, reception is not possible

even if the tuning frequency is correct. This is because the anten-

na terminal input is too weak. Check whether the antenna cable

is firmly connected. If it is, consult your nearest dealer and instalt

an outdoor antenna.

,our dealer to carry out repair work.

Symptom

Power does not come on even

when POWER switch is pressed.

No sound is produced, even

when Function switch is select-

ed.

Sound is produced from one

speaker only.

Noise is produced during recep-

tion of AM broadcasts when the

power switch of other compo-

nents is turned ON or OFF.

High noise level.

Remote control does not work.

Cause

•Power cord is disconnected.

. VOLUME control is set to MIN.

•Speaker connecting wires are disconnected

from speaker terminals.

• One or both of the input cords are disconnect-

ed.

• TAPE 2 MONITOR button is in the ON posi-

tion.

•Speakers buttons are in the OFF position.

• BALANCE control is set too far to one side or

the other.

•One of the speaker connecting wires or input

cords is disconnected.

•AM loop antenna picks up electrical noise

created by switch contacts.

• Station has not been tuned in to correct fre-

quency.

• Antenna has not been connected or has

become disconnected.

FM reception

• Accessory FM antenna remains bundled up.

• Weak broadcasting station signals.

•Noise picked up from other equipment (or, in

particular, from passing automobiles).

• Multipath results when signals from broadcast-

ing station entering antenna directly are mixed

with signals which have been reflected by

mountains or high buildings on their way to an-

tenna, this results in distorted sound and

noise.

AM reception

•AM antenna not pointing in right direction.

• Weak broadcasting station signals.

• Noise being picked up from other equipment

(especially electrical appliances using motor or

fluorescent lights).

• Batteries are dead or no batteries in remote

control unit.

• Poor angle or too great a distance from the re-

mote sensor window.

• There is an obstacle between you and the re-

mote sensor window.

• For CD player and cassette decks, the remote

control cord is not connected.

tion yielding optimum reception.

Replace accessory FM antenna with outdoor

FM antenna.

Try altering direction and mounting position of

antenna. If an outdoor antenna has been erect-

ed, place it as far as possible from passing

traffic and replace connecting cable with 75

coaxial cable.

• Change AM antenna's direction and find a posi-

tion where reception is improved,

• Erect outdoor AM antenna or connect ground

wire.

• Stop using appliances generating noise or re-

move them from vicinity of stereo equipment.

•Insert new batteries.

• Use within 7 meters (23 feet) and within a 30

degree angle of the remote sensor window.

• Change your position or move the obstacle.

• Correctly connect remote control cord.

• Turn off the light.

Abnormal functioning of this unit may be caused by lightning, static electricity, or other external interference. To restore normal operation,

turn the power off and then on again, or unplug the AC power cord and then plug it in again.

Selectingfine audit> ¢quipnlcnt r,uch a_ the unit _ou'_c ju_,t

purchased is only the start of your musical enjoyment. No_ it's

time to consider how you can maximize the fun and excitemcnt

your equipment offers. This manufacturer and the Electronic

Industries 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 annoying blaring or distortion--and, most importantly,

without affecting your sensitive heating.

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.

"I_king 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.

We Want You Listening For A Lifetime

[ised wisely, your new sound equipment will provide a

lifetime of fun and enjoyment. Since hearing damage from loud

noise is often undetectable until it is too late, this manufacturer

and the Electronic Industries Association's Consumer Electronics

Group recommend you avoid prolonged exposure to excessive

noise. This list of sound levels is included for your protection.

Decibel

Level Example

30 Quiet library, soft whispers

40 Living room, refrigerator, bedroom away from traffic

50 Light traffic, normal conversation, quiet office

60 Air conditioner at 20 feet, sewing machine

70 Vacuum cleaner, hair dryer, noisy restaurant

80 Average city traffic, garbage disposals, alarm clock

at two feet.

THE FOLLOWING NOISES CAN BE DANGEROUS

UNDER CONSTANT EXPOSURE

90 Subway, motorcycle, truck traffic, lawn mower

100 Garbage truck, chain saw, pneumatic drill

120 Rock band concert in front of speakers, thunderclap

140 Gunshot blast, jet plane

180 Rocket launching pad

cord, or pinch the cord. Never make a knot in the cord or tie it

with other cords, the power cords should be routed such that

they are not likely to be stepped on, A damaged power cord can

cause fire or give you an electrical shock. Check the power cord

once in a while. When you find it damaged, ask your nearest

PIONEER authorized service center or your dealer for a replace-

ment.

MAINTENANCE OF EXTERNAL SUR-

FACES

•Use a polishing cloth or dry cloth to wipe off dust and dirt.

• When the surfaces are very dirty, wipe with a soft cloth

dipped in some neutral cleanser diluted five or six times

with water, and wrung out well, and then wipe again with

a dry cloth. Do not use furniture wax or cleaners.
