radiation exposure.
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 soldering or
unsoldering.
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.

TEST MODE
4-1. GENERAL
Lead wires: 4 leads
• When entered in the TEST MODE, this set provides the Overall
Adjustment mode which allows CD and MO discs to be automatically adjusted. In the Overall Adjustment mode, performs
adjustments in sequence automatically, and displays the faulty
location if any fault is found. In the Manual mode, selected adjustments can be performed automatically.
• Operations in the Overall Adjustment mode can be performed
either via the main unit, or the keys of a remote control unit.
Note that this device does not include a remote control unit.
Therefore, since no connection terminals for a remote control
are provided either, a connection device must be used in order
to allow a suitable remote control unit to be connected.

The remote control display varies with the type of
remote control unit used.
(Example shown: RM-MC10L)
• The current display is retained as long as either the PLAY
MODE/DISPLAY key on the main unit or the PLAY MODE
key on the remote control unit is pressed and held.
4-2-3. How to release the TEST MODE
When method 1 was used:
Turn off the power and open the solder bridge on BP801 on the
main board.
Note: The solder should be removed clean. The remaining solder
may make a short with the chassis and other part.
When method 2 or 3 was used:
Turn off the power.
Note: If electrical adjustment (see page 8) has not been finished
completely, always start in the test mode. (The set cannot
start in normal mode)
The Manual mode is designed to perform adjustments and
operational checks on the set’s operation according to each
individual function.
Usually, no adjustments are made in this mode.
However, the Manual mode is used to clear the memory before
performing automatic adjustments in the Overall Adjustment mode.
* Manual mode operation can only be performed via the remote
control unit.
Use the connection tool to connect the remote control unit. The
display of the main unit shows “Adj”.
4-4-2. How to set the Manual mode
1. Set the TEST MODE and press + key to set the Manual mode.

the formula below, and press the pause key on the remote
control unit to write this value to NV.
Formula: X x 1.18 = Y
* Since X and Y are 2’sC, attention must be paid to codes.
And the maximum value of Y must be 7Fh. (Never set it to
the negative value.)
Example: Since X = 2Bh, Y = 2Bh x 1.18 = 33h
