• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.

Catch
Cautions
•This unit is designed for negative earth 12 V DC
operation only.
•Do not get the wires under a screw, or caught in
moving parts (e.g. seat railing).
•Before making connections, turn the car ignition
off to avoid short circuits.
•Connect the yellow and red power input leads
only after all other leads have been connected.
•Run all earth wires to a common earth point.
•Be sure to insulate any loose unconnected wires
with electrical tape for safety.
Notes on the power supply cord (yellow)
•When connecting this unit in combination with
•When connecting this unit in combination with
other stereo components, the connected car
circuit’s rating must be higher than the sum of
each component’s fuse.
•When no car circuits are rated high enough,
connect the unit directly to the battery.
Parts Iist (1)
•The numbers in the list are keyed to those in the
instructions.
•The bracket 1 and the protection collar 5 are
attached to the unit before shipping. Before
mounting the unit, use the release keys 7 to
remove the bracket 1 and the protection collar

from the unit. For details, see “Removing the
protection collar and the bracket (4)” on the
reverse side of the sheet.
•Keep the release keys 7 for future use as
they are also necessary if you remove the unit
from your car.

Caution
Handle the bracket 1 carefully to avoid injuring
your fingers.
Note
Before installing, make sure that the catches on both
sides of the bracket 1 are bent inwards 2 mm. If the
catches are straight or bent outwards, the unit will not
be installed securely and may spring out.
