NOTES ON ASSEMBLING THE MECHANISM

1. Fasten Screw A so that the interval (a) will be about 5.2mm
and the interval (b) will be about 2.6mm (The interval (a)
can be measured using a pair of vernier calipers or similar
tools.)

2. Turn B so that Position (0) will come at about the center of
interval (d).

3. Then, play the test disc and fine tune A or B so that the jitter
value would be minimized.

0 How to enter the test mode

There are two different ways to enter the test mode as shown

below.

1) While pressing [SRC key + ATT key] at the same time, reset
the unit.

2) Connect to LX connector odd jigging for writing regions
(2DIN: When adjusting flicker)
Note1 : The jig setting is arbitrary. Note that, however, there
are functions according the setting SW. (Region/Serial/Se-
curity/CPPM)
Note2: In the test mode, power supply is cut off after 30
minutes. (This is for making the operation possible without
Security input even when the security is On.)

0 Adjustment items

Items to be adjusted after writing on the EEPROM on which
regions have been written.

As for the details of the adjustments, refer to each adjustment
item.

- Service Information/Serial Code writing

- Chroma adjustment

- Writing Touch Adjust values

- Screen position adjustment

- Panel mechanism position adjustment

- Writing Security Code (Other than K/R desinations)

0 How to clear the Security Code

In adjusting K/R destination units, if the unit starts up with

Security ON, the Security Code can be cleared in the follow-

ing manner. (Other than in Test Mode)

1) In the e Security ON condition, after resetting or turning
power ON after backup OFF, then the session starts with
Security Code Input screen.

2) With the attached remote control in the Audio SW selected
condition, input the code with the following procedure.
Procedure 1: K input (Press Tenkey [5] 2 times)
Procedure 2: C" input (Press Tenkey [2] 3 times)
Procedure 3: A input (Press Tenkey [2] once)

Procedure 4: Q input (Press Tenkey [7] 2 times)
Note: If a remote controller other than the attached is
used, Pressing Tenkey [7] twice will cause R" to be in-
put.
If a mistake is made during Procedure 1~4 above, input
other remote controller Key. Then, start inputting again
from Procedure 1.

3) Security Code is complete when the input screen for the
Security Code is cleared.
