Power Supply

• Use only the special NP-40 rechargeable lithium ion battery to power this camera. Use of any other type of battery is not supported.

• This camera does not have a separate battery for the clock. The date and time settings of the camera are cleared whenever power is totally cut off (from both the battery and USB cradle). Be sure to reconfigure these settings after power is interrupted.

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.

PROGRAM VERSION UPGRADING

1. To update the firmware version

1. Prepare the memory card which contains the firmware for EX-Z57 in the root directory. EX-Z57.bin

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

3. Press the [power button] while holding [MENU] depressed. Keep holding [MENU] depressed until

“PROGRAM UPDATE” appears in the display.

• The following appears.

• The version of the firmware in the memory card appears at the bottom of the display.

NOTE 1) When a wrong software is mistakenly used,

PROGRAM UPDATE

YES

NO NEW VERSION IS VER 1.00

(As of March 2005)

the message below appears. Update the firmware again with the correct software.

FILE ERROR!

NOTE 2) When only the version appears in the display

even though you are trying to operate the camera, charge the battery to the fullest and try again. The level of the battery indicator should be highest in order to update the firmware.

4. Align the white cursor to [YES] by [UPPER] and [DOWN], and then press [SET].

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

5. “COMPLETE” appears after the update finishes.

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

• “VER.1.00” appears.

VER 1.00

(As of March 2005)

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

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

2. How to restore the firmware

1. Prepare the firmware restoration program and change its name as follows; rom840-1000100.lbn  jupiter.bin NOTE: This software and procedure automatically restores the firmware even if the firmware belongs

to a wrong model code. Make sure to use the correct software for the correct model.

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. NOTE: This software and procedure automatically restores the firmware even if the battery capacity of

the camera is low. Make sure to use a fully charged battery to prevent the danger of power down during firmware restoration.

5. Turn the power on while pressing the [shutter release] button. If the power does not turn on only by pressing the power button, insert the battery while holding the

[shutter release] button depressed.

• The LED next to the optical viewfinder changes from “green/red blinking”, “green blinking” to “green steady”. NOTE: This software and procedure automatically restores the firmware even if the firmware belongs

to a wrong model code. Make sure to use the correct software for the correct mode.

6. When the LED becomes “green steady”, the firmware restoration is finished. Remove the battery and the memory card, and then turn the power off.

7. Turn the power on again while holding [MENU] and [UPPER] depressed. Check the model name and the program version (PR:) in the opening screen of the test menu. ++KX840++ Ver 1.00

8. If the model name and the program version are correct, perform SYSTEM INITIAL to initialize the system area.

“MENU + UPPER + PW ON”  “DOWN, DOWN, DISP, MENU”  “7:ROM UPDATE”  “5:SYSTEM INITIAL”

NOTE: After SYSTEM INITIAL is performed, “SYSTEM ERROR” appears when the power is turned

on again.

9. Write the latest firmware. After the firmware is written, check the model name and the program version (PR:) in the opening

screen of the test menu.

10. Finally, start the camera normally to check the operation by recording, playing back and deleting an image. Check also that the colors in the images are not too bright or two dark.

3. To install the firmware

Initially, firmware is not installed in the PCB supplied by the parts center. Install the firmware into the PCB after replacing with a new one as shown in the procedures below. NOTE: The camera does not operate (only LED becomes “green blinking”) if the firmware is not installed

in the PCB.

1. Copy the following software to the root directly of the SD card. Restoration software: rom840-1000100.lbn Firmware: EX-Z57.bin

2. Change the name as follows; “rom840-1000100.lbn” to “jupiter.bin”

3. Insert the SD card into the camera.

4. Insert the battery while holding the [shutter release] button depressed. The LED next to the optical viewfinder changes from “green/red blinking”, “green blinking” to “green

steady”.

5. When the LED becomes “green steady”, remove the battery and turn the power off.

1. Boot the test mode.

2. Press [DOWN] twice and then press [DISP], [MENU].

3. Select “7: ROM UPDATE” and then press [SET].

4. Select “5: SYSTEM INITIALIZE” and then press [SET].

5. When the following message appears, press [SET]. SYSTEM INITIALIZE START…. PUSH OK KEY?

6. The system initialize is executed. Turn off the power when “SUCCESS” appears. * “SYSTEM ERROR” appears when the camera is turned off without system initialize.

1. Turn the power on while holding [MENU] depressed.

2. When “PROGRAM UPDATE” appears, select “YES” and then press [SET].

3. “NOW LOADING” appears while the firmware is updated.

4. When “COMPLETE” appears, the firmware update is complete.

5. Turn the power on and off to check if the camera normally functions. If there is no problem, the firmware update is successful.
