Caution
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
Dispose of used batteries according to the instructions.
CHEMICALS
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 expo-
sure to high temperature or direct sunlight.
• Avoid dividing chemicals into excessive numbers of small con-
tainers to reduce natural evaporation.
• Keep containers sealed to avoid natural evaporation when chemi-
cals are not in use.
• Avoid using chemicals as much as possible. When using chemi-
cals, divide only required amount to a small plate from the con-
tainer and use up it.
EXTERIOR PARTS
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.
SAFETY CHECK-OUT
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 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.
UNLEADED SOLDER
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.)
: 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 unleaded solder and leaded solder will cause detachment
phenomenon.
注意
如果电池更换不当会有爆炸危险。
只能用同样类型或等效类型的电池来更换。
务必按照说明处置用完的电池。
