Premium Audio System - Jeep J-10 Series 1982 Technical & Service Manual

3V-4 RADIO SOUND SYSTEMS
Stereo Test Tape
A Stereo Test Tape Cartridge, J-22683-01, is available
for checking the operation of the tape player. This tape
provides a means of checking the player for propertape
speed, crosstalk and sound. Follow the instructions on
the tape cartridge.
Tape Head and Capstan Cleaning
One major cause of improper tape player operation is
oxide buildup on the head. During normal operation,
iron oxide particles are loosened from the tape and built
up on the head. This accumulation of oxide can cause
poor playback and some up and down tape travel. The
head and drive capstan should be cleaned whenever the
unit is serviced, or when poor playback or tape travel is
noted.
Cleaning may be done either in the vehicle or on a
service bench. To clean the head, use a cotton swab
moistened with commercially available tape head
cleaner or isopropyl alcohol. Wipe capstan and tape head
dry (fig. 3V-5). If a commercial tape head cleaner is
used, follow the manufacturer's recommended cleaning
procedure.
