Adjustment Procedures

PROCEDURE 1 : Copy the "PSA3040.FIR" File to the CF Card

Two methods are provided for copying the "PSA3040.FIR" file to the CF card.



1. Insert the formatted CF card into the card reader.

2. Copy the "PSA3040.FIR" file from the downloaded data to the CF card.

Note :

Please confirm that both the copied file on the CF card and the original one on your PC have the same file size before proceeding with the camera adjustment.

Windows® : Right-click the file icon and select [Property]
Mac OS : Click the file icon while pressing the control key and select [Information]

* If you use a PC card reader or a notebook type PC with a PC card slot, a CF-to-PC card adapter is required.



1. Insert the CF card into the camera, and connect it to the PC* with an USB cable.
2. Double-click the "UploadFirmware" in the "A3040_Adjustment" folder, and follow the instructions so that the "PSA3040.FIR" file can be copied onto the CF card in the camera **.


Including Windows® XP with the latest version of driver software.


The Main Dial of the camera should be set to (Replay) mode while the PC is connected.

When you attempt to transfer the data to the CF card in the camera with the "UploadFirmware", do not open the CF card slot cover, turn the Main Dial or turn the power off until the data transfer is completed.

Any of the above operations during data transfer will disable the camera adjustment.

PROCEDURE 2 : Start the Camera with Replay Mode


Ensure the camera is powered by the brand-new alkaline batteries or fully charged NB-1AH nickel-metal-hydride batteries.
