Notes on chip component replacement
· Never reuse a disconnected chip component.
· Notice that the minus side of a tantalum capacitor may be
damaged by heat.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, "metallized" knobs, screws,
and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers' instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The "limit" indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range are suitable. (See
Fig. A)

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 viscou-s (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.
NOTE WHEN MEASURING THE VOLTAGE OF THE
CIRCUITS THAT USE VIRTUAL GROUND
This set contains the circuits that take grounding not from usual
ground but from virtual ground.
When measuring circuits in the D-AM and TERM COM boards
and the circuits in MOTHER COM and DC DIF boards that take
"VIRTUAL GND" or "V-GND" as a ground, take grounding from
CN3804 pin 2 of the MOTHER COM board.
NOTES ON REPLACEMENT OF ILINK BOARD
New part of flash memory (IC3001) on the ILINK board cannot be
used.
Therefore, if the mounted ILINK board is replaced, exchange new
flash memory (IC3001) with that used before the replacement.
NOTE OF HANDLING THE ILINK BOARD (Part No. A-
1126-993-A)
When the ILINK board is replaced by a repair for a fee, throw away
the ILINK board after obtaining consent of not returning of the
ILINK board to the customer. When throwing away the ILINK board,
be sure to throw away after destroying IC3205 and IC3208 physically
with the hammer etc.
