Connector Pin No. Specified voltage
W100 1pin (+5V)
4pin (VP)
5pin (FL1)
6pin (FL2)
W201 1pin (-VA)
3pin (+VA)
CB601 1pin (+12V)
4pin (+5V)
2. Turn off the power to check the condition of the CDR drive section.
3. Disconnect the IDE cable.
4. Turn on the power and check the CDR drive section for proper operation.
(Check the condition of the CDR drive.)
The CDR drive should operate by itself.
(Focusing, disc motor revolution)
Operation failure means defective CDR drive.
5. Turn on the power again and check the CPU and FL display for proper operation.
Does the FL display light up after a few seconds?
Is the FL driver accessed?
(FL DATA, FL SCK, FL N CS)
6. Turn off the power and connect the IDE cable.
7. Start the TEST program and check the condition of the main P.C.B.(by using the self-
diagnosis function).
When skipping occurs from time to time, playback/recording is disabled.
1. Using a standard disc (TDK CD-RXA74 or TDK CD-RWXA74), check if recording and playback are executable.
CAUTION: How to handle discs
• Handle the disc with special care not to scratch it or make it dirty. Also do not expose it to ultra-violet rays when keeping it in
storage. (Greater care should be used than when handling a CD disc.)
• CD-RW74 can be used repeatedly but use a number of 20 times as a rough standard for the limit.
• If the CD-R is a self-record/playback type, it can be reused (for additional recording) unless it is finalized.
(Nothing can be recorded additionally if finalized.)
The CD-R disc which has not been finalized cannot be played back on a general type CD player..
• To play back the CD-RW, an applicable type CD player must be used.
