INITIAL SETTINGS
PROCEDURES:
 Preparation. Proceed the picture back up from the unit .
 Step 1. The temporary cancellation of initial setting:
Set the REC/PLAY switch to “[ Recording ]”.
Set the mode dial to “[ P ]”.
While keep pressing [ AF macro/Focus button ] and “[ UP ] of Cursor button” simultaneously, turn the Power on.
Step 2. The cancellation of initial setting:
Set the REC/PLAY switch to “[ Playback ]”.
Press [ AF macro/Focus switch ] and “[ UP ] of Cursor button” simultaneously, turn the Power off.
Step 3. Turn the Power on:
Set the REC/PLAY switch to “[Recording]”, turn the Power on.
Step 4. Display the INITIAL SETTING:
While keep pressing [ MENU ] and “[ RIGHT ] of Cursor button” simultaneously, turn the Power off.
When Main PCB/Flash ROM is replaced, all of the model suffix is displayed as follows.
There are two kinds of “INITIAL SETTINGS” menu format.
Step 5. Set the INITIAL SETTING:
The model suffix can be chosen JUST ONE TIME.
Once one of the model suffix have been chosen, the model suffix lists will not be displayed, thus, it can not be changed. Select the area carefully.
Select the area with pressing “[ UP ]/[ DOWN ] of Cursor button”, and then press the “[ RIGHT ] of Cursor button”
The only set area is displayed, and then press the “[ RIGHT ] of Cursor button” after confirmation.
(The unit is powered off automatically.)
Confirm the display of “PLEASE SET THE CLOCK” in English when the unit is turned on again.
Step 6. CONFIRMATION:
The display shows “PLEASE SET THE CLOCK” when turn the Power on again.
When the unit is connected to PC with USB cable, it is detected as removable media.
Error Code Memory Function
How to display
The error code can be displayed by the following procedure:
Before perform the error code memory function, connect the AC adaptor or insert the battery.
(Since this unit has built-in memory, this error code memory function can be performed without inserting SD memory card.)
1. The temporary cancellation of initial setting:
Set the REC/PLAY switch to “[Recording]”.
Set the mode dial to “[ P ]”.
While keep pressing [ AF macro/Focus switch ] and “[ UP ] of Cursor button” simultaneously, turn the Power on.
2. The display of error code:
Press [ AF macro/Focus switch ], [MENU] and “[ LEFT ] of Cursor button” simultaneously with the step 1 condition.
The display is changed as shown below when the above buttons is pressed simultaneously.
Normal display > Error code display > Operation history display > Normal display > .....
3. The change of display:
The error code can be memorized 16 error codes in sequence, however it is displayed 5 errors on the LCD.
Display can be changed by the following procedure:
“[ UP ] or [ DOWN ] of Cursor button” : It can be scroll up or down one.
“[ LEFT ] or [ RIGHT ] of Cursor button” : It can be display last 5 error or another 5 error.
4. How to read the error date:
The error date code is displayed from the left in order at the year, month, day, time.
Error date information is acquired from “Clock setting” information when the error occurs.
When the clock in not setting, it is displayed as “00000000”.
How to Discharge the Capacitor on Main PCB
This unit equipped with two pieces of capacitors as flash charging capacitors.
“Either one of the capacitor discharging operation” makes discharging for others as well.
CAUTION:
1. Be sure to discharge the capacitor on MAIN PCB.
2. Be careful of the high voltage circuit on MAIN PCB when servicing.
Discharging Procedure
1. Refer to the disassemble procedure and remove the necessary parts/unit.
2. Put the insulation tube onto the lead part of Resistor (ERG5SJ102:1kΩ /5W).
(An equivalent type of resistor may be used.)
3. Put the resistor between both terminals of capacitor on MAIN PCB for approx. 5 seconds.
4. After discharging confirm that the capacitor voltage is lower than 10V using a voltmeter.

How to Replace the Lithium Battery
Replacement Procedure
1. Remove the Main PCB.
2. Remove the Lithium battery (Ref. No. at component side of Main PCB) and then replace it into new one.
Note:
The lithium battery is a critical component.
(Type No.: ML-614S/ZT )
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in equipment designed specifically for its use.
Replacement batteries must be of the same type and manufacture.
They must be fitted in the same manner and location as the original battery, with the correct polarity contacts observed.
Do not attempt to re-charge the old battery or re-use it for any other purpose.
It should be disposed of in waste products destined for burial rather than incineration.
