SAFETY PRECAUTIONS

The following check should be performed for the continued
protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground (water
pipe, conduit, etc.) by connecting a leakage current tester
such as Simpson Model 229-2 or equivalent between the
earth ground and all exposed metal parts of the appliance
(input/output terminals, screw heads, metal overlays,
control shaft, etc.). Plug the AC line cord of the appliance
directly into a 120V AC 60Hz outlet and turn the AC power
switch on. Any current measured must not exceed 0.5mA.

Reading should
not be above

0.5mA

Device
under
test

Test all
exposed metal
surfaces

Leakage
current
tester

ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL
SHOCK HAZARD AND MUST BE CORRECTED BEFORE
RETURNING THE APPLIANCE TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance have
special safety related characteristics. These are often not
evident from visual inspection nor the protection afforded
by them necessarily can be obtained by using replacement
components rated for voltage, wattage, etc. Replacement
parts which have these special safety characteristics are
identified in this Service Manual.

Electrical components having such features are identified
by marking with a on the schematics and on the parts list
in this Service Manual.
The use of a substitute replacement component which does
not have the same safety characteristics as the PIONEER
recommended replacement one, shown in the parts list in
this Service Manual, may create shock, fire, or other
hazards.

Also test with
plug reversed
(Using AC adapter
plug as required)

AC Leakage Test

Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
information, always consult the current PIONEER Service
Manual. A subscription to, or additional copies of, PIONEER
Service Manual may be obtained at a nominal charge from

Additional Laser Caution

1. Laser Interlock Mechanism
The position of the switch (S601) for detecting loading
state is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch
(S601) is not on CLMP terminal side (CLMP signal is OFF
or high level.). Thus, the interlock will no longer function if
the switch (S601) is deliberately set to CLMP terminal side
(low level).
The interlock also does not function in the test mode *.
Laser diode oscillation will continue, if pin 1 of M51593FP
(IC101) on the PRE-AMP BOARD ASSY mounted on the
pickup assembly is connected to GND, or pin 19 is
connected to low level (ON), or else the terminals of Q101
are shorted to each other (fault condition).

2. When the cover is opened with the servo mechanism block
removed and turned over, close viewing of the objective
lens with the naked eye will cause exposure to a Class 1
laser beam.

Remote control may be impossible if there is an obstacle between the
remote control unit and main unit or if the remote control unit is operated
at too great of an angle from the remote control sensor.

·

Erroneous operation may occur if strong light such as direct sunlight or
fluorescent lamp light is incident to the remote control sensor.

·

The main unit may operate erroneously if it is used near equipment
radiating infrared rays or if it is used near control unit of other equipment
is used near the unit. On the contrary, if this remote control unit is operated
near another piece of equipment which can be control wit infrared rays,
the equipment may operate erroneously.

Note 1: Attach the remote sensor of the laser power meter to a point angled away

about 10 degrees against the pickup lens and where the maximum power
is detected, so that there will be no light reflected onto the pickup.

Note 2: When adjusting with VR101 to VR106, first turn them completely counter-

clockwise and then adjust clockwise, so that the value to be reached is not

exceeded.
Note 3: Set the wavelength of laser power meter to 780 nm.

• PCMD is an MSB first, two's complement output.

Notes)

• GTOP is used to monitor the frame sync protection status. (High: sync protection window released)

• XUGF is the negative pulse for the frame sync derived from the EFM signal. It is the signal before sync protection.

• XPCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge of XPCK and the EFM signal transition point coincide.

• GFS goes high when the frame sync and the insertion protection timing match.

• RFCK is derived with the crystal accuracy. This signal has a cycle of 136us.

• C2PO represents the data error status.

• XROF is generated when the 32K RAM exceeds the ±28 Frame jitter match.
