Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
Dispose of used batteries according to the instructions.

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 plastic parts used in this unit.

•  Use a piece of cleaning paper or cleaning cloth for cleaning plastic 

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 

plastic part.

 

Be careful not to tighten screws too much.

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 
customer 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
 

•   Keep the temperature of the soldering iron around 350°C during 

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.

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.
(Caution:  Some printed circuit boards may not come printed with the 

lead free mark due to their particular size.)

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 
unleaded solder and leaded solder will cause detachment phenom-
enon.
