2-4-5. Electronic Volume Adjustment

1. Set the value of ROB_BRT_SENS_DAC_VAL as shown in the table below.
Item VPL-FHZ65/F630HZ/
F635HZ
ROB_BRT_SENS_ 114
DAC_VAL
2. Adjust ROB_BCH_VREGISTOR, and set to the value just before SENSOR_OUT_I becomes "1".
n
. Do not set ROB_BCH_VREGISTER to less than 5.
. The change of 0 → 1 takes only 1 second to be reflected, however, the change of 1 → 0 takes 4 seconds.
3. Set the value of RUBY_BRT_SENS_DAC_VAL as shown in the table below.
Item VPL-FHZ65/F630HZ/

4. Adjust RUBY_BCH_VREGISTOR, and set to the value just before GPIO_SONY_OPT_SENS
becomes "1".
n
. Do not set RUBY_BCH_VREGISTER to less than 5.
. The change of 0 → 1 takes only 1 second to be reflected, however, the change of 1 → 0 takes 4 seconds.

2-4-6. Luminance Constant Mode Adjustment

1. Read the value of SENSOR_OUT_ADC.
2. Set this value to LAMP_MAX_BRT.
