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.
