Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270˚C during
repairing.

• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering or
unsoldering.

Notes on Chip Component Replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be damaged

by heat.

UNLEADED SOLDER

•

Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350°C.
Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE
WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN
THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.
REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE
PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR
IN SUPPLEMENTS PUBLISHED BY SONY.

3. DSP Adjust

•This mode executes DSP LOOP BACK.

4. Lcd Contrast

• This mode adjusts the LCD contrast.
The initial value is 40.

• Adjust the contrast using the > and . keys.

5. Lcd Check

•This mode verifies that all LCD indicators are on and off, and it
checks the PATTERN, vertical scroll and horizontal scroll displays.

[PLAY]: All On > : Vertical scroll
[REC]: All Off
[DIVIDE]: PATTERN

. : Horizontal scroll

6. Language

• Not used.

7. Loop Back

•This mode executes DSP LOOP BACK.

• MENU is turned on and off.

[PLAY]: Execute (only at a stop).
[DIVIDE]: MUTE ON/OFF.
[MENU]: Exit from Submenu.

(After an execution is stopped during execution.)

x : During execution: Termination of execution.

At a stop: Exit from submenu.

8. RTC Int

•This mode checks for RTC operation.

9. System

•This mode checks the NOR, NAND, UNIQUE and MS.

10. Battery

•This mode checks the current value of A/D.

11. DC-IN

•This mode checks the current value of DC-IN A/D.

• NG is displayed for non-connection.

12. Initialize

•This mode initializes the set values (to the values established at
the factory).

13. Nand init

• Band Block and NAND formatting of the NAND FLASH.

14. Nand Format

•NAND formatting.

15. F/W update

• Update of the F/W.

15-1. F/W UpGrade method

If the F/W need be updated for reasons such as modification of
bugs after mass production, the F/W should be updated as follows:

1. Copy the following files just under the drive of the memory stick
Duo.
(The files below will be distributed when bugs are modified.)

• ldrasm.mot (upgrade driver)

• CHIPEXEC.MOT (F/W for the set)

• update.pls (upgrade MS identification file)

2. Insert the MS described in step 1 into the set and turn on power.
(Use a new battery or the AC adapter.)

3. When the ACCESS screen remains as it is and the OPE-LED
(red) lights up, the update is completed.
Remove the battery and remove the MS Duo. The F/W update is
complete.
Enter the Test Mode and check the version.

4. Once the F/W is updated, the update.pls file is automatically
deleted.
If you are repeating to upgrade the F/W, the update.pls file should
be copied again.

Supplement:

If you are upgrading a large number of sets for mass production,
the testmode.ind file should be added which enables repeated
upgrade.

• ldrasm.mot (upgrade driver)

• CHIPEXEC.MOT (F/W for the set)

• update.pls (upgrade MS identification file)

• testmode.ind (special file for the factory)

Caution:

If the power is down during upgrade or the memory stick is removed,
this upgrade fails.
(This will cause malfunctions, failure of power-on, and errors during
operation.)
If these conditions are caused, the set must be disassembled and
upgraded. Contact the design department.

The following files can be created by creating an arbitrary text file
and changing its name.

• update.pls (upgrade MS identification file)

• testmode.ind (special file for the factory)
