ference even when it is operating
properly. To eliminate interference,
you can try one or more of the follow-
ing corrective measures.
• Reorient or relocate the TV or
radio’s receiving antenna.
• Increase the distance between
the system and the TV or radio.
• Use outlets on different electrical
circuits for the system and the
TV or radio.

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

8
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).

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.
