FEATURES
RECORDING
You can record as you sing along with the music from another audio source. You can also record
only the sound from the external audio source.
RECORDING TIPS
Tape quality greatly affects the quality of the recording. We recommend Extended Range or Low-
Noise Type 1 tape. We do not recommend long-play cassette tapes, such as C-120s, because they
are thin and can easily tangle in the cassette mechanism. For low-noise, wide-range recordings, use
normal-bias tape.
Before recording, be sure the tape you are using has its erase-protection tabs in place. See
“Preventing Accidental Erasure”.
Recording automatically stops when the tape reaches the end. To record on the other side, turn over
the tape.
RECORDING YOUR VOICE WITH MUSIC
Follow these steps to record your voice along with music from an audio source connected to the
system’s AUX INPUT jack.
1. Load a blank tape, or one that you want to record over into the system’s cassette
compartment, with the side you want to record on facing you, and the full reel to the left.
2. Follow Steps 1-5 under “Singing with Another Audio Source”.
3. Press RECORD on the system to begin recording. RECORD and PLAY will both locks down.
4. Press STOP/EJECT on the system to stop recording. RECORD and PLAY will release.

FEATURES
MAINTENANCE
Your MKS 2450 Memorex Single Cassette Recorder Karaoke System is an example of superior
design and craftsmanship. The following suggestions will help you care for the 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.
•Use and store the karaoke system only in normal temperature environments. Temperature
extremes can
shorten the life of electronic devices and distort or melt plastic parts.
•Keep the karaoke system away from dust and dirt, which can cause premature wear of parts.
•Handle the karaoke system gently and carefully. Dropping it can damage circuit boards and
cabinet and
can cause the karaoke system to work improperly.
•Wipe the karaoke system with a cloth occasionally to keep it looking new. Do not use harsh
chemicals, cleaning solvents, or strong detergents to clean the karaoke system.
Modifying or tampering with the karaoke system’s internal components can cause a malfunction and
will invalidate its warranty.

Preventing Accidental Erasure

FEATURES
Cassette tapes have two erase-protection tabs ---- one for each side. To protect a recording from being
accidentally recorded over or erased, use a screwdriver to remove one or both of the cassette tape’s erase-
protection tabs.
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.
Notes:
•Be sure you cover only the hole originally covered by the erase-protection tab.
•Removing the erase-protection tabs does not prevent a bulk eraser from erasing a cassette tape.
Erasing a Cassette Tape
If you no longer want a recording, you can record over it or erase it.
To erase a previously recorded section of a tape, simply record over it.
To erase the entire cassette tape, record silence to the end with all controls set to their minimum
settings and the microphone(s) turned off.
You can quickly erase both sides of a cassette tape using a bulk tape eraser.
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.
file:///G|/Private/Joe%20Tumminelli/Owner's%20Manuals/MKS2450/MKS2450.htm (13 of 16) [7/29/2002 4:07:34 PM]

FEATURES
1. Disconnect the AC power cord.
2. Open the cassette compartment doors on the system.
3. Press PLAY on the system 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 heads, pinch rollers, capstans, tape guides, and erase heads.
5. When you finish cleaning, press STOP/EJECT on the system and close the cassette
compartment doors. Then reconnect power.
Restoring Tape Tension and Sound Quality
After you play a cassette tape several times, the tape might become tightly wound on the reels. This
can cause playback sound quality to deteriorate.
To restore the sound quality, fast-forward 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 surface.
Caution: Be careful not to damage the cassette when tapping it. Do not touch the exposed tape or
