ELECTRICAL ADJUSTMENT
The unit has been adjusted optimally at the time of factory shipment. However, if the screen position is deviated or
when exchanging parts, make an adjustment as shown below.
• Turn on the power (lamp on state) and wait for 15 minutes for aging.
• Enter the adjustment process mode with SW2002 (tact switch) on the main unit.
• Select the group to adjust with the DOWN ( " ) key or the UP ( ' ) key on the remote control, and enter the
adjustment item with the ENTER (      ) key on the remote control.
• Select the adjustment item with the DOWN ( " ) key or the UP ( ' ) key on the remote control.
• Use the LEFT ( \ ) key or the RIGHT ( | ) key for adjustment.
• To return from the adjustment item to the adjustment group, use the UNDO (      ) key.
• To exit the adjustment process mode, execute the factory setting at the end of the adjustment.
<Cautions for adjustment>
1) Initialization and factory setting
If the initialization S2 or the factory setting S5 of EEPROM is carried out, time for writing the data is necessary.
When the initialization S2 or the factory setting S5 of EEPROM are executed, the OSD display of the adjust-
ment process mode disappears, and INPUT 1 is selected after about 15 seconds. Since the OSD display of
the set 2 or the set 5 appears, never turn off the power until this display appears.
2) AUTO adjustment
At the time of AUTO adjustment, do not bring to the no-signal state. (Do not stop the signal.)
Otherwise the adjustment data may be changed or deleted.
