1. Check the area of your repair for unsoldered or poorly-sol-
dered 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 transis-
tors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
4. Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and recom-
mend 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 270 °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 sol-
dering or unsoldering.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.

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
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 viscous (sticky, less prone to flow) than
ordinary solder so use caution not to let solder bridges occur
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.

[Discharging of the DD-158 board's charging capacitor
(C506)]
The charging capacitor (C506) of the DD-158 board is charged up
to the maximum 300 V potential.
There is a danger of electric shock by this high voltage when the
battery is handled by hand. The electric shock is caused by the
charged voltage which is kept without discharging when the main
power of the unit is simply turned off. Therefore, the remaining
voltage must be discharged as described below.
Preparing the Short Jig
To preparing the short jig, a small clip is attached to each end of a
resistor of 1 k
/1 W (1-215-869-11).
Wrap insulating tape fully around the leads of the resistor to pre-
vent electrical shock.
1 k
/1 W
Wrap insulating tape.
Discharging the Capacitor
Short-circuit between the positive and the negative terminals of
charged capacitor with the short jig about 10 seconds.
SERVICE NOTE
· NOTE FOR REPAIR
Make sure that the flat cable and flexible board are not cracked of
bent at the terminal.
Do not insert the cable insufficiently nor crookedly.
Cut and remove the part of gilt
which comes off at the point.
(Be careful or some
pieces of gilt may be left inside)
When remove a connector, don't pull at wire of connector.
It is possible that a wire is snapped.
When installing a connector, don't press down at wire of connector.
It is possible that a wire is snapped.
