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.

Cautions
• This unit is designed for negative ground 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 ground wires to a common ground
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.
