FOLLOW THESE PROCEDURES

Turn the computer off.

Press EJECT to open cover, then press PLAY to expose heads.

Put tape head cleaner on one side of a cotton swab. Gently wipe the sur·

faces of RECORD/PLAY and erase head (see Fig. 1).

Scrub gently. (If there is any build-up of tape oxide particles on or around

the head gap of the RECORD/PLAY head, it is sufficient reason for unreli-

able performance.)

Also clean pinch roller and other tape bearing surfaces if tape head cleaner

is suitable for this purpose (check label ).

Plug in demagnetizer, and activate it while it is at least one foot away

from cassette heads.

Slowly move demagnetizer up to RECORD/PLAY head and around on

head surface. Rate of motion should be approximately one inch per second

during this time.

Slowly move demagnetizer to erase head and then to all other ferrous metal

surfaces which come into proximity with the tape.

Now slowly move demagnetizer away from heads. Do not deactivate field

until demagnetizer is at least two feet away from heads.

The tape head cleaning and demagnetizing procedure is now complete. Inspect

Y, surface for wear. If the tape has worn a groove on head surface

more than a couple of tape thicknesses deep, program reading performance may be

poor. If so, then replacement of tape head is indicated. (Normally few thousand

hours of tape running time have been completed before replacement is required.)
