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.).
