  3. CW INDEX
・ When the color wheel is replaced, adjust the "Color Wheel Index Adjustment".
   Refer to the "SECTION 3. ADJUSTMENT PROCEDURE" about method.
  4. POWER OFF MESSAGE
・ Setting of the shutter function with standby operation
- SHUTTER KEEP: When push the standby key with shutter ON, keep the shutter mode. 
- SHUTTER OPEN: When push the standby key with shutter ON, open the shutter and display
                               the "Power OFF confirmation message". (Default setting)
  5. ERROR OSD
・ When do not watch the error instructions LED of the lamp by a rear projection, the errors of the lamp can be
  displayed in the OSD.
- ON: "Lamp error message" is displayed on OSD.
- OFF: Does not display the "Lamp error message" in OSD.
  6. MODEL
・ Set this when the A-P.C.Board is replaced.
* If you can copy EEPROM data from the old A-P.C.Board, this setting is unnecessary.
* This model setting is changed after turn power on and off.
  7. CLOG SENSOR CALIBRATION
・Calibrate the clogging sensor circuit.
  Execute this after EEPROM(IC3103/IC3104)/A-P.C.Board or Airflow sensor (M2-P.C.Board) is replaced.
 * Refer to the "SECTION3 (ADJUSTMENT PROCEDURE)" about method.
    3. 3. 2. Additional function of each menu
  1. "PICTURE" menu
The following one item is added.
・Ye MODULATE
When PICTURE MODE menu is displayed, adjustment can be done by ENTER button.
ON: Ye MODULATE function is active
OFF: Ye MODULATE function is not active
  2. "POSITION" menu
The following one item is added.
・DVI EQUALIZER
When noise appears with DVI input caused by length of cable or external device, set this item 
so that the noise decreases.
  2. "ADVANCED" menu.
The following 4 items are added.
* Following items do not usually change the setting.
・FRAME LOCK
Set this item when moving picture is disturbed with RGB input.
・480i SD
When non-standard signal of 480i/576i is inputted (AV amplifier, etc), synchronization might be disordered
 according to connected equipment. In this case, set 480i SD to ON.
・480p OS
When 480p/576p is received, aliasing noise (longitudinal striated beat noise) might be generated according to
connected equipment. In this case, set 480p OS to ON. However, the resolution decreases a little.
・H PLL
When non-standard signal is inputted (VCR, VHD, etc), horizontal synchronization might be disordered according to
connected equipment. In this case, set H PLL to OFF.

    4. 1. 6. Basic format
The transmission from PC starts with STX, ID, Command, Parameter and EXT are sent in order.
Parameter is added depending on the control.
1. Basic control command (No parameter)
2. Basic control command (with Parameter)
3. Basic control command (with sub command)
4. Calculation
Direction of how to deal the indicated value by parameter
Direction
 Set the value of indicated value by parameter.
 Add the indicated value by parameter on current value.
5. Code
Direction of plus / minus for the indicated value by parameter
Direction
 The value indicated by parameter is plus. ( If it is 0, set this.)
 The value indicated by parameter is minus.
6. Parameter
Indicate the setting or adjustment value with right justification.( 0 is not suppressed.)
For example, indicate "00001" for the setting value "1".
7. ID for the basic commands
・This projector will respond to the computer only in the following cases.
Respond only when the transmitted ID is matched to this projector's ID.
RESPONSE(ID ALL) in RS232C settings of this projector is ON and the sent ID is ALL.
RESPONSE(ID GROUP) in RS232C settings of this projector is ON.
・Specifically, please refer to "Control Commands List"
8. Response of basic control commands
In accepted period
It depends on each command.
Out of accepted period or no command
Parameter or REMOTE 2 terminal is active
9. Note
There is a possibility that a command is not accepted about 60 seconds after lamp is ON.. In this case, 
try again after 60 seconds.
When plural commands are sent, please make sure that next command is sent more than 0.5 seconds after 
receiving the response from this projector.
There is a case that it takes some time for responding because of internal processing.
Please set the timeout period to more than 10 seconds until the responses comes back.
