CONNECTIONS  
If you are operating the system using  
battery power and the sound be-  
comes weak or distorted, replace the  
batteries.  
CONNECTING POWER  
Installing Batteries  
You can power your system with six  
D batteries (not supplied). For the  
best performance, we recommend  
alkaline batteries, such as Radio  
Shack Cat. No. 23-550.  
Caution: To avoid damage from  
leaking batteries, remove the batter-  
ies if you do not plan to use the sys-  
tem for a week or more. Also, do not  
leave batteries in the system if you  
plan to use AC or DC power for an  
extended period of time.  
Follow these steps to install the bat-  
teries.  
1. Press the battery compartment  
cover’s tab and lift off the cover.  
Using AC Power  
You can power the system from a  
standard AC outlet using the sup-  
plied AC adapter.  
Cautions:  
2. Install the batteries in the com-  
partment as indicated by the  
polarity symbols (+ and –)  
marked next to the compart-  
ment.  
• The adapter must supply 9 volts,  
its center tip must be set to neg-  
ative, it must deliver 500 milli-  
amps, and its plug must  
correctly fit the DC 9V INPUT  
jack. The supplied adapter  
meets  
these  
requirements.  
Using any other adapter could  
damage the system or the  
adapter.  
• Always unplug the adapter from  
the AC outlet before unplugging  
it from the system.  
Note: Use only fresh batteries of  
the required size and type.  
Always remove old or weak bat-  
teries. Batteries can leak chemi-  
cals that can destroy electronic  
circuits.  
1. Remove the supplied AC  
adapter from the microphone/  
adapter compartment on the  
back of the system.  
3. Replace the cover.

and damage to the system and vehi-  
cle, always unplug the adapter from  
the cigarette-lighter socket before  
unplugging it from the system.  
3. Plug the adapter into a standard  
AC outlet.  
CONNECTING  
ANOTHER AUDIO  
SOURCE  
Using Vehicle Battery Power  
You can power the system from your  
vehicle’s battery if the vehicle has a  
12-volt DC, negative-ground electri-  
cal system. This connection requires  
a DC adapter, such as Cat. No. 270-  
1562.  
You can connect another audio  
source (such as a stereo VCR or CD  
player) to the system so you can sing  
along with the audio source’s sound.  
Connect the source’s headphone  
output jack to the system’s AUX IN-  
PUT jack.  
Cautions:  
• If you are not sure what type of  
electrical system your vehicle  
has, check with the vehicle  
dealer.  
• The adapter must supply 9 volts,  
its center tip must be set to neg-  
ative, it must deliver 500 milli-  
amps, and its plug must  
correctly fit the DC 9V INPUT  
jack. The recommended adapter

Note:  
OUT jacks (such as those found on a  
stereo VCR or CD player), use a  
shielded Y-adapter cord with phono  
plugs on each end (such as Cat. No.  
42- 2475). Connect the end with the  
single plug to the system’s AUX IN-  
PUT jack and connect the other end’s  
two phono plugs to the AUX OUT  
jacks on the audio source.  
meets

SINGING ALONG  
Now get ready for some fun! In this  
section, we tell you how to use your  
system’s karaoke features. First, set  
the system’s and the source’s vol-  
ume controls to their minimum set-  
tings. Then plug the supplied  
microphone’s 1/4-inch plug into MIC 1  
or MIC 2.

karaoke cassette tape, lets you sing  
along with the music only (MUSIC set-  
ting), with both the prerecorded sing-  
er’s voice and the music (NORMAL),  
or with the prerecorded singer’s  
voice at normal volume and the mu-  
sic at a lower volume (VOCAL).  
Note: Your friend can also sing along  
with the music if you connect a unidi-  
rectional 600-ohm dynamic micro-  
phone with a 1/4-inch plug to the  
system’s other MIC jack. For the best  
performance, we recommend Cat.  
No. 33-992.

source connected to the system’s  
AUX INPUT jack.  
RECORDING TIPS  
1. Load a blank cassette tape or  
one that you want to record over  
into the system’s cassette com-  
partment.  
Tape quality greatly affects the  
quality of the recording. We rec-  
ommend Radio Shack Extended  
Range or Low-Noise Type 1  
tape.  
Note: If you are using a prere-  
corded cassette tape as your  
music source, load that tape in  
the audio source’s cassette  
compartment.  
• Before recording, be sure the  
tape you are recording on has its  
erase-protection tabs in place  
(see “Preventing Accidental Era-  
sure”).

MAINTENANCE  
Your Radio Shack Karaoke Cassette Recorder System is an example of superior  
design and craftsmanship. The following suggestions will help you care for your  
system so you can enjoy it for years.  
Keep the system dry. If it gets wet, wipe it dry immediately. Liquids  
might contain minerals that can corrode the electronic circuits.  
Handle the system gently and carefully. Dropping it can damage  
circuit boards and cases and can cause the system to work im-  
properly.  
Use and store the system only in normal temperature environ-  
ments. Temperature extremes can shorten the life of electronic  
devices and distort or melt plastic parts.  
Keep the system away from dust and dirt, which can cause pre-  
mature wear of parts.  
Wipe the system with a damp cloth occasionally to keep it looking  
CLEANER  
new. Do not use harsh chemicals, cleaning solvents, or strong de-  
tergents to clean the system.  
Modifying or tampering with the system’s internal components can cause a mal-  
function and might invalidate your system’s warranty. If your system is not per-  
forming as it should, take it to your local Radio Shack store for assistance.  
15  
 
32-1156.fm Page 16 Monday, August 9, 1999 2:24 PM  
If you want to record on a tape side  
after you have removed the erase-  
protection tab, place a piece of  
strong plastic tape over that side’s  
erase-protection hole. Be sure you  
cover only the hole originally covered  
by the erase-protection tab.  
TAPE TIPS  
Erasing a Cassette Tape  
To erase a previously recorded sec-  
tion of a tape, simply record over it.  
To erase the entire cassette tape, let  
the tape record silence to the end  
with all controls set to their minimum  
settings and the microphone(s)  
turned off.  
Note: Removing the erase-protec-  
tion tabs does not prevent a bulk  
eraser from erasing a cassette tape.  
You can quickly erase both sides of a  
cassette tape using a bulk tape eras-  
er (Cat. No. 44-232), available at  
your local Radio Shack store.  
Restoring Tape Tension and  
Sound Quality  
After you play a cassette tape sever-  
al times, the tape might become  
tightly wound on the reels. This can  
cause playback sound quality to de-  
teriorate.  
Preventing Accidental  
Erasure  
Cassette tapes have two erase-pro-  
tection tabs — one for each side. To  
protect a recording from being acci-  
dentally recorded over or erased,  
use a screwdriver to remove one or  
both of the cassette tape’s erase-  
protection tabs.  
To restore the sound quality, fast-for-  
ward the tape from the beginning to  
the end of one side, then completely  
rewind it. Then loosen the tape reels  
by gently tapping each side of the  
cassette’s outer shell on a flat sur-  
face.  
Caution: Be careful not to damage  
the cassette when tapping it. Do not  
touch the exposed tape or allow any  
sharp objects near the cassette.

32-1156.fm Page 17 Monday, August 9, 1999 2:24 PM  
Cleaning the Tape-Handling  
Parts  
Dirt, dust or particles of the tape’s  
coating can accumulate on the tape  
heads and other parts that the tape  
touches. This can greatly reduce the  
performance of the cassette player.  
Use the following cleaning procedure  
after every 20 hours of tape player  
operation.  
1. Remove the batteries and dis-  
connect the AC or DC power  
cord.  
2. Open the cassette compartment  
door.  
3. Press PLAY to expose the tape-  
handling parts.  
4. Use a cotton swab dipped in  
denatured alcohol or tape head-  
cleaning solution to clean the  
record/play head, pinch roller,  
capstan, and erase head.  
5. When you finish cleaning, press  
STOP/EJECT and close the cas-  
sette compartment door.  
Your local Radio Shack store sells a  
complete line of cassette cleaning  
supplies.
