whose amperage rating is identical. Use of a
fuse of higher amperage may cause serious
damage to the unit.
• Keep screwdrivers, etc. and other metallic or
magnetic objects away from the playback head.
• When your car was parked in direct sunlight
resulting in a considerable rise in temperature
inside the car, allow the unit to cool off before

Keep cassettes away from equipment with builtin magnets to avoid unwanted noise or loss of
sound quality.
Do NOT touch the tape of a cassette, as any dirt
or dust will contaminate the heads.
Be sure to remove any cassette from the unit if
you are not using it.
