ADJUSTMENT PRECAUTIONS
This model's setting are adjusted in two dif
ferent 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 122 & JA 124 for 1 second and release to switch to the service mode position, and the
microprocessor is in input mode. (Adjustment through the I
2
C 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 122 & JA 124 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 122 & JA 124 for 1 second and release to switch to the service mode position and turn on the
main power switch.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 5 & 6.
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 JA122 & JA124 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.
