• 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.

• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

In checking the display board and main board, prepare two jigs
(connection cable J-2502-066-2 and
connection cable for F/P to main J-2502-071-1).

Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 ˚C higher than

ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 ˚C.
Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

• Strong viscosity

Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges oc-
cur such as on IC pins, etc.

• Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

• This unit is designed for negative earth 12 V

DC operation only.

• Do not get the leads 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 power connecting lead 

7 to the

unit and speakers before connecting it to the
auxiliary power connector.

• Run all earth leads to a common earth

• Be sure to insulate any loose unconnected

leads with electrical tape for safety.

Notes on the power supply lead (yellow)
• 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.

• The numbers in the list are keyed to those in

the instructions.

• The bracket 

1 and the protection collar 4 are

attached to the unit before shipping. Before
mounting the unit, use the release keys 

6 to

remove the bracket 

1 and the protection collar

4 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
