OPERATION AND MAINTENANCE
Maintenance
The playback head is a very important part of the tape
playback system. If it becomes dirty, the sound quality will
deteriorate resulting is loss of fidelity (high frequency
reproduction). The head should be cleaned every 20 hours of
use. (Approximately)
1. Press the eject button and open the cassette door.
2. Clean the playback head with a cotton applicator (Q-tip) and
alcohol. Soak the cotton applicator in the alcohol and rub the
face of the head until it is clean. Never use sharp objects to
perform cleaning.
Caution:
Cassette tape should be stored in a container or vinyl bag to
prevent contamination by moisture and dust. Tapes should not
be placed in locations exposed to sunlight or in the vicinity of
any magnetic field such as televisions or stereo speakers.
Be sure and eject the tape before turning off the unit. If a
cassette is left engaged in the mechanism. a flat spot will
develop from the pressure of the capstan and pinch roller, thus
causing uneven sound reproduction and damage to your
tapes.
Before inserting a cassette into the unit, look through the
cassette window to make sure that there is no excess slack,
several loose turns. If necessary, insert a pencil or similar
object in the reel hub (figure A) and rotate it to take up the
slack, If a poor quality tape or a 120 minute tape is used in this
unit the tape may become entangled with the capstan and
break. We recommend no longer than 90 minute, good quality
brand name cassettes be used in the LS7000.
