Power Supply

• Use only the special NP-20 rechargeable lithium ion battery to power this camera. Use of any other type of battery is not supported.

• This camera does not require a battery for the clock. The date and time settings of the camera are cleared whenever power supplied by both the battery and USB cradle is interrupted. Be sure to reconfigure these settings after power is interrupted (page

39).

LCD Panel

• The LCD panel is a product of the latest LCD manufacturing technology that provides a pixel yield of 99.99%. This means that less than 0.01% of the total pixels are defective (they do not turn on or always remain turned on).

Lens

• You may sometimes notice some distortion in certain types of images, such as a slight bend in lines that should be straight. This is due to the characteristics of lens, and does not indicate malfunction of the camera.

1. How to confirm the program version

■ The program version can be confirmed in the test menu (refer to the previous page).

■ Turn the power on while pressing MENU button.

The following program version can be found. Check the LCD display. (Example)

VER 1.00

(As of September 10. 2003)

2. How to update the firmware

1. Prepare the memory card which contains the software for upgrading EX-S20/M20 firmware in the root directory.

firmware: EX-S20................. ex-s20.bin

EX-M20 ................ ex-m20.bin

The firmware is included in the service CD-ROM. The location is as follows: QV/Soft/Adj-soft/EXs20_m20/FirmUP

2. Insert the above memory card in the camera and then set a fully charged battery in the camera.

3. While pressing MENU, press power switch. Keep pressing MENU until “PROGRAM UPDATE” appears in the camera LCD.

• The following appears.

• The version for the firmware update software in the memory card appears at the bottom.

PROGRAM UPDATE YES NO NEW VERSION IS VER 1.00

Note: This does not appear when the battery is low. Make sure to charge the battery fully.

4. Align the white cursor to “YES” by the cross key of 왖 and 왔, and press SET of the center of the cross key.

• “NOW LOADING” appears in the LCD and the update starts.

5. “COMPLETE” appears after the update finishes.

— 6 —

6. Remove the memory card after turning the power off once. Turn the power back on again while pressing MENU, and check the version.

VER 1.00

(As of September. 2003)

7. If the version is correct, turn the power off.

8. Finally, check the operation by recording, playing back and deleting an image.

3. How to restore the firmware

1. Prepare the following firmware restoration program and change its name as follows; EX-S20: rom858_030908.lbn 앶앸 jupiter.bin EX-M20: rom859_030908.lbn 앶앸 jupiter.bin The program is included in the service CD-ROM. Location: QV/Soft/Adj-soft/EXs20_m20/Recover

2. Copy the above file to the root directory in the memory card.

3. Insert the memory card into the camera.

4. Set a fully charged battery in the camera.

5. Turn the power on while pressing the shutter release button. The LED next to the optical finder changes from green/red blinks 앶앸 green blinks 앶앸 green lights.

6. When the green LED lights, the firmware restoration is finished. Remove the battery.

7. Turn the power on again while pressing MENU and DISP buttons. The firmware is successfully restored if the following version appears. EX-S20: PR: 03.09.08.13.22 EX-M20: PR: 03.09.08.13.25

8. Finally, start the camera normally to check the operation by recording, playing back and deleting an image.

ADJ TOOL

■ Introduction Make sure to perform the adjustment when replacing the lens unit or the MAIN PCB. The necessary software, driver and setting are explained in using USB ADJ Tool "adj03natsu.exe". Note that the tool, drivers etc. are available only for Windows.

1. How to use USB ADJ Tool 1-1. Prepare the necessary software, driver and DLL file.

(1) Prepare the following three files.

• Commom test driver for CASIO/PENTAX

[testmode_pentax_casio] folder uusbd.dll

uusbd.inf uusbd.sys

• ADJ data read/write tool "adj03natsu.exe"

• Commom DLL for USB test "uusbd.dll"

(2) Place the commom test driver for CASIO/PENTAX in an appropriate place. (3) After downloading the common DLL for USB test, copy it to the same directory as that of the ADJ data

read/write tool or under "c:windows/system.

1-2. Set the camera so that it recognizes the USB test mode.

(1) Enter the test mode and then the initial test selection screen.

Turn the power on while pressing both "MENU" and "DISP".

Press "RIGHT", "RIGHT" and "MENU. (2) Move the cursor to "3:USB TCC TEST" and press "SET". (3) Move the cursor to "1:USB TCC ON" and press "SET". (4) Press "MENU" button and leave the test mode. (5) This enables the camera to recognise the USB test mode flag. (6) When the USB test mode flag is ON, the test menu appears first when the camera power is turned on. * If the USB test mode flag should be OFF, set "2: USB TCC OFF" in the test menu.

1-3. Install the USB driver for the USB test mode in the computer. (The following is an example using the Windows Me.)

(1) Prepare the USB driver for the USB test mode. (2) Turn the camera power on which is set in the USB test mode and let it enter the USB test mode as

shown in 1-2.(the test menu appears right after the power is turned on). (3) Connect the camera in the above status to the computer by the USB cable. (4) "A wizard for the new hardware" appears. (5) Check "Designate the place for the driver (for users with sufficient knowledge)" and press "Next". (6) Check "Search for the optimum driver for the device (recommended)". (7) Check "Designate the place to search" , designate the place which contains "inf" file in the driver by

pressing "Reference" button, and then press "Next" button. (8) When "Universal USB Driver (VMEM manufacturer's name)" appears upon message "Searching for

the driver file for the following devices" , press "Next" button. (9) The file copy starts.

(If a message "uusbd.Inf cannot be found" appears during the file copy, designate the same place as in

the step 7).

(10) Press "Complete" button. (11) Right-click "My computer", select "Property" and open "Device manager". If "Universal USB Driver

(VMEM manufacturer's name)" can be found in "USB device for UUSBD", the computer has successfully

recognised the driver.

(12) The test driver can be used for both CASIO/PENTAX. Installing the test driver into either one enables

the other one to recognise it.

— 8 —

NOTE: How to uninstall the USB driver for the USB test mode

• Connect the camera while in the USB test mode to the computer so that the computer recognises the camera.

• Right-click "My computer", select "Property" and open "Device manager".

• Select "USB device for UUSBD" , and then "Universal USB Driver (VMEM manufacturer's name)".

• Press "Delete" button and delete the driver.

• When using Windows98/98SE/Me, delete the following three files;

(NOTE! Do NOT delete "usbd. inf" and "usbd.sys", whose names are much alike the following.) C:windows / inf / uusbd.inf C:windows / inf / other / KashiwanoUUSBD.inf C:windows / system32 / drivers / uusbd.sys

• The driver has been successfully deleted.

1-4. Use the USB ADJ Tool

(1) Prepare ADJ data read/write tool "adj03natsu.exe". (2) Copy the common DLL for USB test to the same directory as that of the ADJ data read/write tool

"adj03natsu.exe" or under "c:windows / system".

(3) Turn the camera power on which is set in the USB test mode and let it enter the USB test mode (the test

menu appears right after the power is turned on). Connect the camera to the computer by the USB cable.

(4) Boot "adj03natsu.exe" and use it as follows;

• Read ADJ data from the camera.  Press "read from the camera".

• Write ADJ data into the camera.  Press "write into the camera".

• Save ADJ data which is read.  Press "File" and "Save", and save it with an appropriate name.

• Open ADJ data which is saved.  Press "File" and "Open", and open the necessary file.
