Cassette tape player operating tips
Use only cassette tapes of good quality, having no damage.
Avoid using tapes with a total playing time longer than 90

When not in use, take the cassette out of the player, put it
back into its case and store it away from dust, magnets and
direct sunlight.

your tapes.
Keep the interior mechanism of the cassette player clean.
Once or twice a month, use a wet type cleaning cassette to
clean off tape coating residue accumulated on the head,
capstan and pinch roller.

anything
other than cassette tapes into the slot, or the tape
player may be damaged.
