SHOCK, FIRE HAZARD SERVICETEST :
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.

1. How to enter into the Service Mode
Turn the power on while pressing [PLAY]+[OPEN/
CLOSE] buttons together.
2. Mode 0 (display “P 00”)
Condition: [FOCUS OFF], [SPINDLE OFF], [RADIAL
OFF], [MUTE ON]
•While pressing [ ](Remote Control unit only) button,
the sledge moves outside.
And, release from this button. The sledge return to
neutral position.
•Press [NEXT ] button, the function will change to
“Mode 1”.
3. Mode 1 (display “P 01”)
Condition: [FOCUS ON], [SPINDLE OFF], [RADIAL OFF],
[MUTE ON]
•Press [NEXT ] button, the function will change to
“Mode 2”.
•Press [PREV ] button, the function will change to
“Mode 0”.
4. Mode 2 (display “P 02”)
Condition: [FOCUS ON], [SPINDLE ON], [RADIAL OFF],
[MUTE ON]
•Press [NEXT ] button, the function will change to
“Mode 3”.
•Press [PREV ] button, the function will change to
“Mode 1”.
5. Mode 3 (display “P 03”)
Condition: [FOCUS ON], [SPINDLE ON], [RADIAL ON],
