Beforeusing 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.

Placement

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 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 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, ANSIINFPA 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.

(NEC ART 250, PART H)

1. Ventilation -- The unit should be situated so that its location

or position does not interfere with its proper ventilation. Allow

10 crn (4") clearance from the rear of the unit.

2. Foreign Material -- Care should be taken so that objects do

not fall intoand _iquids 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.

Main tenan ce

Clean the cabinet, panel and controls with a soft cloth lightly
moistened with mild detergent solution.

Do not use any type of abrasive pad, scouring powder or solvent
such as alcohol or 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;

or

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

or

(c) The unit has been exposed to rain; or
(d) The unit does not appear to operate normally or exhibits a

marked change in performance; or

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

2.

Servicing -- The user should not attempt to service the unit
beyond that described in the operating instructions. All other

servicing should be referred to qualified service personnel.

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 5°C
(41°F) or greater than 35°C (95°F).

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.

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.

We Want You Listening For A Lifetime

Useclwisely, 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.

*The level used here is different from that displayed on the

Preset tuning

By presetting the desired broadcast stations into the memory
channels of this unit, broadcast stations can be selected simply
by pressing numeric button(s). (Refer to page 20 for tuning.)

-Before presetting

How many broadcast stations can be preset?

A total of 30 FM and AM stations can be preset.

How Is presetting done?

The two following methods are available.

• Automatic memory presetting

Automatic memory presetting allows this unit to automatical-
ly search for broadcast stations and then preset them into
memory.
With this function, searching proceeds from the frequency
currently being displayed and continues through higher fre-

quencies, (up to 107.9 MHz for FM, up to 1710 kHz for AM)

and broadcast stations are preset in the order in which they
are located.

With this method, the channel ranges that can be preset into
the memory for different bands (FM or AM) are set as

follows.

Channel

v _,.;.Q;_ P,.;,,;,v oi_tOt.n;;tO;he

.... Tuning intervals

AM: 10 kHz interval

FM: 200 kHz interval

If either button is pressed and held

down until the frequency begins to
change, the broadcast stations can be

tuned automatically when a broadcast
station is found.

Tuning may stop automatically if any
jamming is encountered.

For FM broadcast stations ........................ 1 -30

For AM broadcast stations ....................... 21-30

If the FM stations (channels 1-30) ere preset and then
the AM stations (channels 21-30) are preset:

Because this unit can accommodate a total of 30 preset
channels, the settings for FM channels 21 - 30 will be replac-
ed by the AM settings which were subsequently preset, and

the channel allotment will be as shown below.

Channel

I- FM

For FM broadcast stations........................I-20

For AM broadcast stations.......................21- 30

> < AM_

• Manual memory presetting

The desired broadcast stations can be preset into the
desired channels by the user.
This can also be used as a method for changing selected
broadcast stations that were preset in "Automatic memory
presetting".

Please remember this:

If a new broadcast station is preset into a channel, the set-
ting for the broadcast station which was previously entered
in that channel will be automatically erased.

The channel number is not displayed if you change the reception
frequency or FM mode setting.

For your reference:

Even if the power is switched to the standby condition or the
power cord is disconnected from the household AC outlet, the

contents of the memory will continue to be stored for approx-

imately one month.

If frequency presettings are accidentally erased

Make the frequency presettings once again.
The power cord should remain connected for one hour or more

for the memory back-up to be effective.
