ADJUSTMENT PRECAUTIONS
This model's setting are adjusted in two different ways: through the I
2
C bus control and in the conventional
analog manner. The adjustments via the I
2
C bus control include preset-only items and variable data.
1. Setting the service mode by the microprocessor.
1. Short JA 137 & JA 138 for 1 second and release to switch to the service mode position, and the
microprocessor is in input mode. (Adjustment through the I2C bus control). (Use JWS Key to set as
well).
2. Press the CH DOWN / UP key on the remote controller to get ready to select the mode one by one.
3. Press the CH DOWN / UP key on the remote controller to select the modes reversibly one by one.
4. Using the VOLUME UP/ DOWN key on the remote controller, the data can be modified.
5. Short JA 137 & JA 138 for 1 second and release to switch to the normal mode (OFF) position, and the
microprocessor is in out of the service mode.
2. Factory Presetting.
1. Short JA 137 & JA 138, then turn on the main power and release to switch to the Service Mode position.
Initial values are automatically preset, only when a new EEPROM is used (Judge
with the first 4 bytes ).
2. The initial data are preset as listed in page 8, 9, & 10.
3. Make sure the data need modify or not (Initial data).
Note: Once the chassis has been assembly together and ready to be POWER ON for the FIRST TIME,
make sure to short JA137 & JA138 to switch to the service mode position first and then turn on the
main power switch (See 2-(1) above).
Precaution: If haven't done this initiation, it may possibly generate excessive Beam current.
3. For reference please check with memory map
(GA-1 Series type RH-iX3368CE N6)

CAUTION: Make sure TV set is in "Normal condition" before switch to Service Mode for adjustment.
