AL-2051 SIMULATION, TROUBLE CODES 10 - 20

46 19 Exposure mode setup [Function]

γ table setting>

When this simulation is executed, the code number of the current set gamma table is displayed.

(Default: 2)

Enter the code number corresponding to the desired gamma table, and press [ ] [ ] key to

change the mode and write into the EEPROM.

When setting the

γ table, press [ ] key to change to the AE operation mode, and the current

set code number of the AE operation mode is displayed. (Default: 0)

Enter the code number corresponding to the desired AE operation mode and press [ ] [ ]

key to change the mode and write into the EEPROM.

When [ ] key is pressed in AE operation mode setting, the mode is changed to the PHOTO

image process setting and the code number of the current set PHOTO image process setting is

displayed. (Default: 1)

Enter the code number corresponding to the desired PHOTO image process setting and press

[ ] [ ] key to change the mode and write into the EEPROM.

[Operation]

The operation is similar to simulation 43-01.

20 RSPF exposure correction [Function]

Used to adjust the exposure correction amount in the RSPF mode. The adjustment is made by

adjusting Vref voltage variation for the OC mode.

When this simulation is executed, the current set value is displayed in 2 digits (Default: 50).

Change the set value and press [START] key to save the setting and make a copy.

When the set value is increased, copy becomes darker. When the set value is decreased, copy

becomes lighter. (Adjustment range: 1 – 99)

[Operation]

The operation is similar to simulation 46-01.
