1. SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
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.
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, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA.
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. 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 PIONEER.

Additional Laser Caution
1. Laser Interlock Mechanism The position of the switch (S1801) for detecting loading completion is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch is not in LPS1 terminal side (when the mechanism is not clamped and LPS1 signal is high level.) Thus, the interlock will no longer function if the switch is deliberately set to LPS1 terminal side. ( if LPS1 signal is low level ). In the test mode* the interlock mechanism will not function. Laser diode oscillation will continue, if pin 41 of TC94A15FG (IC502) on the MAIN Assy is connected to GND, or else the terminals of Q501 are shorted to each other (fault condition). 2. When the cover is opened, close viewing of the objective lens with the naked eye will cause exposure to a Class 1 laser beam.

1. SERVICE PRECAUTIONS
1.1 NOTES ON SOLDERING
A
· For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering. · Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 °C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 °C in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron. Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden).
B
The following lead-free solders are available as service parts: · Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia.

[Measuring procedure] After entering this mode, rapidly turn the JOG dial, either clockwise or counterclockwise. The figures will be displayed. If, for example, "8.6: 115" is displayed, each figure means the following: 8.6 : Maximum speed (Normal speed is one rotation in 1.8 sec.) 115 : Time (in msec) required for decreasing the rotation speed from 3 times to 1.5 times normal speed To measure the time required for reducing the rotation speed, the maximum speed must be 7.0 times normal speed or higher. If measurements are consecutively performed several times, the mean value of the results of up to four latest measurements will be displayed, in order to minimize variation. Standard value: 95 ± 25 msec [Adjustment procedure] 1. Enter this mode. 2. Adjust the adjustment value of Adjust plate to "0". 3. Rapidly turn the JOG dial, either clockwise or counterclockwise. 4. The rotational speed (maximum speed) and time are displayed in the dot FL display section. · The time required so that the rotation may decrease from 3 times normal speed to 1.5 times normal speed when maximum speed is only 7 times normal speed or more is displayed. · Moreover, the mean value of the measurement result at the rotation decrease time is displayed since the second times. · The thing that the mean value at the decrease of the rotation three times in total time is in the standard value (95 ± 25 msec) is confirmed. Perform the following procedure if coming off from the standard value. 5. When the rotational speed is smaller than 70, the adjustment value of the adjust plate is changed to "-1" and performs the procedure 3 and 4. (1) When the rotational speed is larger than 120, the adjustment value of the adjust plate is changed to "+1" and performs the procedure 3 and 4. (2)
