• Preparation
1.Prepare the H/U (STC-700), and connect the power cord
and the interface cord to it.
2.Prepare the remote controller (RC-DV100), and the op-
eration mode selector switch is made the television mode.
1.Test mode
1-1.How to enter the test mode
While pressing and holdingVOL DOWN and SOURCE keys,
reset the unit.
1-2.How to exit from the test mode
Reset the unit, Momentary power down, ACC OFF and
Power OFF.
(Note) Reset sets all values to initialization values except
for the adjusted with the test mode (ex.Touch panel
adjustment data, etc.).
1-3. Details
1. Control screen (ALL OFF mode) is boot up so that Back
screen color is red.
2. Screen mode is Full.
3. Video In is selected as an input signal.
4. BRT, CONT and BLK are adjusted in 3 steps of Full
Down →
← Center →
← Full Up with the one click.
5. The remote controller SRC key recalls Touch Panel Ad-
justment screen. A cross-cursor (+) touch adjust on the
TOUCH PANEL ADJUST screen allows the reference
points (upper left, upper right and lower left) to be writ-
ten to EEPROM.
6. Video level adjustment
The remote controller DIRECT key allows recall ofVideo
level adjustment mode.
The remote controller BAND▲DISC and ▼M/S keys al-
low adjustment item (CH) selecting.
The remote controller and keys allow adjust-
ment value up/down.
The remote controller key allows adjustment value
fixed (blue →magenta) and adjustment value released
(magenta →blue).
Exit by pressing the remote controller DIRECT key again
so that all items of Video level adjustment to be ended.
2. EEPROM Clear
If and when, for some reasons, the touch panel does not
function due to incorrect values being written to EEPROM,
recovery will be attempted by clearing the EEPROM.
2-1. Setup Method
While pressing and holding VOL DOWN and POWER keys,
reset the unit.
(EEPROM will be clearing at the next POWER ON.)
2-2.Termination Method
POWER ON.
2-3. Contents
The contents of the EEPROM are all re-written to "FF". By
this, the touch panel adjustment and Video level adjust-
ment will function with the ROM fixed value.
3. Attention
3-1. When EEPROM Clear was done, Touch panel adjust-
ment andVideo level adjustment conduct the adjustment
again.
3-2. When the touch panel switch assembly was replaced,
conduct the touch panel adjustment together.
3-3. When LCD assembly was replaced, conduct the Video
level adjustment and the touch panel adjustment to-
gether.

Attention
When Touch Panel Adjustment and Video level adjustment are
done, please use the Remote sensor jig.
Process
(1) Remove the Unit's connector (2 Pin Type).
(2) Connect the BU and GND lines of the Remote sensor jig to the
Power Supply unit.
(3) Insert the jig's connector toward the tip of the arrow.
