SER VICE 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.
(Take care that there are some
pieces of gilt left inside)
When remove a connector, don’t pull at wire of connector.
Be in danger of the snapping of a wire.
When installing a connector, don’t press down at wire of connector.
Be in danger of the snapping of a wire.
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, though 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 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.

5-1-4.Adjusting Remote Commander
The adjusting remote commander is used for changing the calculation coefficient in signal processing, EVR data, etc. The adjusting remote commander performs bi-directional communication
with the unit using the remote commander signal line (LANC).
The resultant data of this bi-directional communication is written
in the non-volatile memory.
1. Used Adjusting Remote Commander
1) Connect the adjusting remote commander to the CN704 on
the VC-211 board via CPC jig (J-649-193-0A).
2) Adjust the HOLD switch of the adjusting remote commander
to “HOLD” (SERVICE position).
3) Turn on the power with the POWER switch of the unit.
If it has been properly connected, the LCD on the adjusting remote commander will display as shown in Fig. 5-1-6.

PageData Address
• Changing the address
The address increases when the FF ()) button is pressed,
and decreases when the REW (0) button is pressed. There
are altogether 256 addresses, from 00 to FF.
• Changing the data (Data setting)
The data increases when the PLAY (() button is pressed,
and decreases when the STOP (p) button is pressed. There
are altogether 256 data, from 00 to FF.
• Writing the adjustment data
The PAUSE button must be pressed to write the adjustment
data in the nonvolatile memory. (The new adjustment data
will not be recorded in the nonvolatile memory if this step is
not performed)
2. Precautions Upon Using the Adjusting Remote
Commander
Mishandling of the adjusting remote commander may erase the
correct adjustment data at times. T o prev ent this, it is recommended
that all adjustment data be noted down before beginning adjustments and new adjustment data after each adjustment.
Fig. 5-1-6
4) Operate the adjusting remote commander as follows.
• Changing the page
The page increases when the EDIT SEARCH + button is
pressed, and decreases when the EDIT SEARCH – button is
pressed. There are altogether 16 pages, from 0 to F.

The calculation of the DDS display and adjusting remote commander display data (hexadecimal notation) are required for obtaining the adjustment data of some adjustment items. In this case,
after converting the hexadecimal notation to decimal notation,
calculate and convert the result to hexadecimal notation, and use
it as the adjustment data. Table 5-1-2. indicates the hexadecimal
notation- the decimal notation, calculation table.
