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
cassette player’s performance. To
prevent noise and poor high-frequen-
cy response, clean the cassette play-
er’s tape-handling parts after every 20
hours of use. Your local RadioShack
store sells a complete line of cassette
deck cleaning supplies.
Follow these steps to clean the tape-
handling parts on your system’s cas-
sette decks.
1. Turn off the system, then unplug
its power cord.
Note:
Unplugging the SYSTEM
745 clears the CD changer’s pro-
grammed sequence memory but
does not clear stations in memory
or category/subcategory names.
2. Press
STOP/EJECT
on both cas-
sette decks. Both cassette com-
partment doors open.
3. Press
PLAY
on both cassette
decks to expose the tape-handling
parts.
4. Use a cotton swab dipped in
denatured alcohol or tape head
cleaning solution to gently clean
the record/play heads, pinch roll-
ers, capstans, tape guides, and
erase head.
5. When you finish cleaning, press
STOP/EJECT
on both cassette
decks to release the play mecha-
nisms, then close both cassette
compartment doors and reconnect
power.
