PRECAUTIONS

• This unit is designed to be operated on a 12-volt DC negative-ground electrical system only.
  •To prevent short-circuiting, disconnect the negative car battery terminal until the unit has been mounted and connected completely.
• When replacing the fuse, be sure to use one 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 operating it.
• Keep the volume at such a level that you can hear outside warning sounds (horns, sirens, etc.).

Notes on cassettes

Do NOT expose cassettes to direct sunlight, extremely high or cold temperature or moisture. Keep cassettes away from equipment with built-in 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.
