ADJUSTMENT INSTRUCTION
1. Application Range
This spec. sheet is applied to all of the PP81D Chassis.
2. Specification
(1) Because this is not a hot chassis, it is not necessary to use
an isolation transformer. However, the use of isolation
transformer will help protect test instrument.
transformer will help protect test instrument.
(2) Adjustment must be done in the correct order.
(3) The adjustment must be performed in the circumstance of
(3) The adjustment must be performed in the circumstance of
25±5
c
C of temperature and 65±10% of relative humidity if
there is no specific designation.
(4) The input voltage of the receiver must keep 100~240V,
50/60Hz.
(5) Before adjustment, execute Heat-Run for 30 minutes at RF
no signal.
3. ADC calibration

[1/2 Black & White Pattern (Refer below picture)].
3) Adjust by commanding AUTO_COLOR_ADJUST(0xF1)
0x00 0x02 instruction.
(2) Confirmation
1) We confirm whether “0xF1(offset), 0xF2(gain)” address of
EEPROM “0xBC” is “0xAA” or not.
2) If “0xF1”, “0xF2” address of EEPROM “0xBC” isn’t “0xAA”,
we adjust once more
3) We can confirm the ADC values from “0x00~0x05”
addresses in a page “0xBC”

Manual ADC process using Service Remocon. After enter
Service Mode by pushing “ADJ” key, execute “Auto-RGB” by
pushing “

EEPROM “0xBC” is “0xAA” or not.
2) If “0xF3”, “0xF4” address of EEPROM “0xBC” isn’t “0xAA”,
we adjust once more
3) We can confirm the ADC values from “0x06~0x0B”
addresses in a page “0xBC”

(CH+/-) key, and press the number key(0~9)
consecutively
ex) If the value of Tool Option1 is 7, input the data using
ex) If the value of Tool Option1 is 7, input the data using
number key “7” (Fig. 2)
Caution: Don’t Push “IN-STOP” key after PCB assembly
adjustment.

About PDP
After done all adjustments, Press IN-START button and
compare Tool option and Area option value with its BOM, if it
is correctly same then Change “RF mode” and then unplug
the AC cable.
If it is not same, then correct it same with BOM and unplug AC
cable.
For correct it to the model°Øs module from factory JIG model.
