SHOCK, FIRE HAZARD SERVICE TEST :
CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC
cord connector pins ( with unit NOT connected to AC mains and its Power switch ON ), and the face or Front Panel of product
and controls and chassis bottom.
Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied,
and verified before it is return to the user/customer.
Ref. UL Standard No. 1492.
In case of difficulties, do not hesitate to contact the Technical
Department at above mentioned address.

2. FACTORY/SERVICE MODE
A.FACTORY MODE
To reset all settings to default status ,follow the procedure
below.
1) When Power Standby mode, While pressing MARK
or MARK and INPUT buttons, Slide POWER switch
to turn on the unit. ( /N uses MARK button. /F/U uses
MARK button.)
2) FACTORY name is displayed on LCD. The unit becomes
the setup of default automatically.
B.SERVICE MODE
1. Micro-Processor Version check
1) Insert the CompactFlash, When Power Standby mode,
While pressing A-B REPEAT and EDIT buttons, Slide
POWER switch to turn on the unit.
2) VIRSION name is displayed on LCD with blink, then press
PLAY/PAUSE button, VIRSION is displayed on LCD.
Example : DSP 02.06
MPU B0004
3) Turn off power to quit Service mode.
2. CompactFlash read/write speed check
1) Insert the CompactFlash, While pressing A-B REPEAT
and EDIT buttons, Slide POWER switch to turn on the
unit.
2) VIRSION name is displayed on LCD with blink, then press
-/F.REV or F.FWD/+ button.
3) CARD CHECK name is displayed on LCD with blink, then
press PLAY/PAUSE button.
The check of Read/write speed is started. After the
check finishes, the number of data transfer rate (kbps) is
displayed.
Start (progress) End
Example : XXX% Read:3606
EXECUTING Write:3606
If "about 3000 or less" number is displayed, the
CompactFlash is not correct (Because read/write speed is
slow, the unit has the possibility that sound is interrupted
and stop during recording).
Insert the correct CompactFlash.
4) Turn off power to quit Service mode.

of the tester becomes 7.0 V ± 0.1 V and confirm the
contrast of the LCD becames maximum.
4. HOW TO DISASSEMBLE
1) Remove 7 screws as shown in Fig.1.
2) Remove the battery cover.
3) Remove 4 screws as shown in Fig.2.
