PREPARATION

Note: Complete all connections

before connecting to power and turn-

ing on the system.

CONNECTING THE

SPEAKERS

1. Press the red speaker terminal

tab labeled SPEAKERS 8WR+ on

the back of the system. Insert

the end of the right speaker’s

red wire into the red (+) terminal,

then release the tab.

2. Press the black speaker terminal

tab labeled SPEAKERS 8WR– on

the back of the system. Insert

the end of the right speaker’s

black wire into the black (–) ter-

minal, then release the tab.

3. Repeat Steps 1 and 2 to connect

the left speaker to the SPEAK-

ERS 8WL + and – terminals.

CONNECTING

ANTENNAS

The system has two antennas. To

connect the supplied AM loop anten-

na, attach it to the AM LOOP

ANTENNA terminals on the back of

the system.

To connect the supplied FM antenna,

attach it to the FM ANTENNA 300W

terminals on the back of the system.

13-1289.fm Page 7 Wednesday, July 14, 1999 6:09 PM

If you have an outside VHF TV

antenna, you can use a signal splitter

with a 300-ohm output to connect

your stereo system and TV set to the

same antenna. Your local Ra-

dioShack store has a wide selection

of antennas, connectors, and split-

ters.

INSTALLING THE

REMOTE CONTROL’S

BATTERIES

The remote control requires two AAA

batteries (not supplied) for power.

For the best performance and long-

est life, we recommend alkaline

batteries, such as RadioShack Cat.

No. 23-555.

Follow these steps to install batter-

ies.

1. Press down and slide off the bat-

tery compartment cover.

2. Install the batteries as indicated

by the polarity symbols (+) and

(–) marked inside the compart-

ment.

3. Replace the cover.

Cautions:

• If you are not going to use the

remote control for a month or

more, remove its batteries. Bat-

teries can leak damaging chemi-

cals.

• Do not mix old and new batter-

ies, different types of batteries

(standard, alkaline, or recharge-

able), or rechargeable batteries

of different capacities.

Note: If the remote control operates

erratically or does not work at all, re-

place both batteries.

CONNECTING TO

POWER

After you complete all connections,

plug the music system’s supplied

power cord into a standard AC outlet.

Warning: To prevent electric shock,

the power cord plug’s blades are po-

larized (one blade is wider than the

other) and fit a polarized AC outlet

only one way. If you have difficulty in-

serting the plug, do not force it. Turn

it over and reinsert it.

The STAND BY indicator lights, and

AM 12:00 flashes on the display

(see “Setting the Clock” on Page 11).

13-1289.fm Page 8 Wednesday, July 14, 1999 6:09 PM

USING HEADPHONES

You can use headphones (not sup-

plied) to listen in privacy. Insert the

headphones’ 1/8-inch plug into the

PHONES jack.

Notes:

• Your local RadioShack store

sells a wide selection of

headphones.

• Connecting headphones auto-

matically disconnects the

speakers.

Listening Safely

To protect your hearing, follow these

guidelines when you use head-

phones.

• Set the volume to the lowest set-

ting before you begin listening.

After you begin listening, adjust

the volume to a comfortable

level.

• Do not listen at extremely high

volume levels. Extended high-

volume listening can lead to

permanent hearing loss.

• Once you set the volume, do not

increase it. Over time, your ears

adapt to the volume level, so a

volume level that does not

cause discomfort might still

damage your hearing.

13-1289.fm Page 9 Wednesday, July 14, 1999 6:09 PM

OPERATION

TURNING POWER ON/

OFF

Warnin

: To protect your hearing,

set VOLUME to its lowest setting

before you turn on the system.

Press POWER to turn on the system.

The STAND BY indicator turns off

and the display lights.

USING THE REMOTE

CONTROL

The remote control’s buttons have

the same functions as the corre-

sponding buttons on the system.

To use the remote control, point it

toward the remote sensor on the left

side of the system’s display and

press the desired buttons.

Notes:

• Make sure you have a clear path

between the remote control and

the sensor.

• Weak batteries or direct sunlight

on the remote sensor might

reduce the remote control’s

operating range.
