6. ADJUSTMENT

6.1 CD ADJUSTMENT

1) Precautions
• This unit uses a single power supply (+5V) for the reg-

ulator. The signal reference potential, therefore, is
connected to VREF(approx. 2.1V) instead of GND.
If VREF and GND are connected to each other by mis-
take during adjustments, not only will it be impossi-
ble to measure the potential correctly, but the servo
will malfunction and a severe shock will be applied to
the pick-up. To avoid this, take special note of the fol-
lowing.
Do not connect the negative probe of the measuring
equipment to VREF and GND together. It is especially
important not to connect the channel 1 negative
probe of the oscilloscope to VREF with the channel 2
negative probe connected to GND.
Since the frame of the measuring instrument is usual-
ly at the same potential as the negative probe, change
the frame of the measuring instrument to floating sta-
tus.
If by accident VREF comes in contact with GND,
immediately switch the regulator or power OFF.

• Always make sure the regulator is OFF when connect-

ing and disconnecting the various filters and wiring
required for measurements.

• Before proceeding to further adjustments and mea-

surements after switching regulator ON, let the player
run for about one minute to allow the circuits to stabi-
lize.

• Since the protective systems in the unit's software are

rendered inoperative in test mode, be very careful to
avoid mechanical and /or electrical shocks to the sys-
tem when making adjustment.

• The RFI and RFO signals are easy to oscillate because

of a wide band. When observing them, insert a resis-
tor of about 1 k

Ω

to the series.

• This equipment will not guarantee the load ejection

operation when the mechanical unit is turned upside
down. In particular, if the ejection operation is incor-
rectly performed and recovery is disabled, the recov-
ery is enabled by resetting a product or turning ACC
off to on.

2) Test Mode
This mode is used for adjusting the CD mechanism
module of the device.

• Test mode starting procedure

Reset while pressing the 4 and 6 keys together.

• Test mode cancellation

Switch ACC, back-up OFF.

• After pressing the EJECT key, do not press any other

key until the disk is completely ejected.

• If the

]

or

[

key is pressed while focus search is in

progress, immediately turn the power off (otherwise
the actuator may be damaged due to adhesion of the
lenses).
