Adjustment Precautions - Sharp 14BM2 Service Manual

ADJUSTMENT PRECAUTIONS

This model's setting are adjusted in two different ways: though the I
conventional analog manner. The adjustments via the I
items and variable data.
1. Setting the service mode by the microprocessor.
1 Short JA122 & JA124 for 1 second and release to switch to the service mode position,
and the microprocessor is in input mode. (Adjustment through the I
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 JA122 & JA124 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 JA122 & JA124 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 pages 4, 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 switch to the service mode posi-
tion 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
