Outline of The flow of battery replacement procedure is as following.
battery
replacement
procedure
1. Remove the insulating sheet and the battery from the FAX board.
2. Install a new battery on the FAX board and stick the insulating sheet.
3. Check the battery voltage.
4. Clear the all memory of the FAX.
Tools
1. A digital tester (Analog testers are not acceptable.)
2. A soldering iron, solder (Wider soldering irons are easier to use.)
3. A phillips-head screwdriver
4. Radio pliers
5. Desoldering equipment
6. Alcohol, waste (for cleaning the board)
7. Short pins
Detailed
procedure
Procedure 1 Remove the insulating sheet and the battery from the FAX board.
(1) Remove the insulating sheet from the backside of the board.
(2) Remove the two battery terminals under the insulating sheet.

Procedure 2 Install a new battery (UBATI0014FCZZ) on the FAX board and stick the insulating sheet.
(1) Insert the battery from the front side of the board, and solder two parts of the terminal.
Insert the battery and the terminal (the outside terminal) aligning them with the
"+" mark of silk screen print.
Note: Cover the holes in the board by solder.
(2) Clean around the soldered area with alcohol.
Remove the residue of solder, dirt, and other foreign material from the insulating
sheet.
(3) Stick the insulating sheet.
Stick the urethan part of the insulating sheet between the battery terminals with
the double-sided tape on the urethan part.
ÿNote: Make sure that the battery terminals are equally covered in terms of the
distance from the sides, the top and the bottom of the insulating sheet.

Procedure 3 Check the battery voltage.
(1) Measure the battery voltage.
The method to measure the battery voltage
The plus probe of the tester : Connect to the terminal of JP4
The minus probe of the tester : Connect to the minus (-) terminal of C257
It is OK if the battery voltage is 3.0V or more.

(2) Measure the decrease of voltage at the both sides of the battery current limiting
resistance .
How to measure the decrease of voltage at the both sides of the battery current

(Note: Make sure not to mistake them because the tester probe polarity of "the
terminal of JP4" is different from (1).)
It is OK if the decrease of voltage on the both ends of the battery current limiting
resistance is 0.06V or less.

(3) The process to conduct when the measurement value is over the standard even
after rechecking the detail of the work.
Check if there is any contamination which may cause short-circuit in the bord. If
there is not, check the detail below.
If the measurement result of (1) is below 3.0V and the measurement result of (2)
is 0.06V or less, failure of the newly-installed batery is suspected. Please
If the measurement result of (1) is 3.0V or more and the measurement result of
(2) is over 0.06V and the causes such as mistakes in soldring work are not
found, the failure of the board is suspected.
If the measurement result of (1) is below 3.0V and the measurement result of (2)
is over 0.06V and the causes such as mistakes in soldring work are not found,
the failure of the board is suspected.
Procedure 4 To clear the all memory of the FAX
(1) Procedure to replace the board
1. Remove the backside steel plate of the machine after confirming that the power is off.
Before removing the steel plate After removing the steel plate

Remove the screws at 5 points.
2. Remove the LIU board.
Remove the screws of the LIU board.
Remove the lock of the spacer which fixes the LIU board with radio pliers etc.
and remove the LIU board.

4. Remove the spacer.
Turn the FAX bord to the backside.
Take off the screws of the spacer with radio pliers and remove it from the board.

5. Take out the PROGRAM ROM from the test machine's FAX board, and install it on
the FAX board which you replaced the battery in the procedure 3.
To take out Push the lever on the right side in, and take out the PROGRAM ROM.
To install Pull out the lever on the right side, and push the PROGRAM ROM in.
Note: Do not conduct the procedure on the ARMM11 which is connected to the
connector for options.

6. Install the FAX board (after the battery is replaced) and LIU board.
The process is the reverse order of (1) -2 to 5.
Note:Make sure to insert the spacer.
Make sure to fasten the screws (8 points).
Make sure to connect the speaker cable.
Do not attach the steel plate removed at (1)-1.
(2) Execute FAX SRAM clear.
1. Insert the short pins (PCAPH0010GCPZ,QSOCN0108FCPZ etc.) to the left side of
SW2 (the side of No.3).
Insert the short pins to
the left side of SW2 (the
side of No.3)

2. Turn on the power switch.
The beeper sounds for 0.9sec twice just after turning on the power switch.
F6-88 error message will be displayed in the display in about 30sec, but disregard it.
Confirm the beeper sounds for 0.9sec three times in about 1minute (Correct
completion).
ÿThe beeper sounds repeatedly until the power switch is turned off ÿat about
4.5sec intervals).ÿ
If it is not completed even after re-checking the detail of the work, check the joint
of the connector on the board. (Connectors and terminals of MAIN, LIU, and
If it does not complete correctly even after that, check the detail below.
If the beeper does not sound even when the power switch is turned on, check
the joint of the connector on the board. (MAIN, LIU, and PROGRAM ROM)
If the cause is not found, failure of the board is suspected.
If the beeper continue to sound when 1minute has past since the power
switch is turned on, failure of the LIU board is suspected. Please replace the
If the beeper does not sound when 1minute has past since the power switch
is turned on, failure of LIU board is suspected. Please replace the LIU board.
If the cause is not found, failure of the board is suspected.
3. Turn off the power switch.
4. Take off the short pin installed at 1.
(3) Execute SRAM memory test.
1. Turn on the power switch.
Note: F6-99 error message may be displayed depending on the setting.
Disregard it if it is displayed.
