Some chemicals used for servicing are highly volatile.
Their evaporation caused by improper management affects your health and environment, and wastes resources.
Manage the chemicals carefully as follows.

•  Store chemicals sealed in a specific place to prevent from exposure to high temperature or direct sunlight.
•  Avoid dividing chemicals into excessive numbers of small containers to reduce natural evaporation.
•  Keep containers sealed to avoid natural evaporation when chemicals are not in use.
•  Avoid using chemicals as much as possible. When using chemicals, divide only required amount to a small plate from the container and 

use up it.

Be careful to the following points for exterior parts used in this unit.

•  Use a piece of cleaning paper or cleaning cloth for cleaning exterior parts. Avoid using chemicals.

Even if you have to use chemicals to clean heavy dirt, don t use paint thinner, ketone, nor alcohol.

•  Insert the specific screws vertically to the part when installing a exterior part.

Be careful not to tighten screws too much.

This unit uses unleaded solder.
Boards requiring use of unleaded solder are printed with the lead free mark (LF) indicating the solder contains no lead.

(

 Some printed circuit boards may not come printed with the lead free mark due to their particular size.)

: LEAD FREE MARK

Be careful to the following points to solder or unsolder.

•  Set the soldering iron tip temperature to 350  C approximately.

If cannot control temperature, solder/unsolder at high temperature for a short time.
Caution:

   The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful!

Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC 
pins, etc.

•  Be sure to control soldering iron tips used for unleaded solder and those for leaded solder so they are managed separately. Mixing un-

leaded solder and leaded solder will cause detachment phenomenon.

After correcting the original service problem, perform the following safety checks before releasing the set to the customer.

1.  Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and 

bridges.

2.  Check the interboard wiring to ensure that no wires are  pinched  or contact high-wattage resistors.
3.  Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the cus-

tomer and recommend their replacement.

4.  Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recommend their 

replacement.

5.  Check the B+ voltage to see it is at the values specified.
6.  Flexible Circuit Board Repairing

•  Set the soldering iron tip temperature to 350  C approximately.
•  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.

Danger of explosion if battery is incorrectly replaced.

Replace only with the same or equivalent type.

Dispose of used batteries according to the instructions.

Make sure that the conductive side of a flexible board does not have any stain or foreign materials.
Do not touch the conductive side of flexible boards with bare hands.
Plug in a flexible board straight, fully into the connector until it reaches the end inside. (Fig. 1, Fig. 2, Fig. 3)

OK 

(The flexible board was plugged in straight 
and completely)

•  Make sure that the flat cable and flexible board are not cracked 

or bent at the contact end.

•  Do not apply excessive force to the gilded flexible board.

Cut and remove the part of gilt
which comes off at the point.
(Be careful or some
pieces of gilt may be left inside)

•  The proper way to disconnect a connector is to grab the con-

nector instead of the wires.  If you pull on the wires, they might 
be broken.
