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 60Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5mA.
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.

7.1.3 Operation of the Fan-Control Line
1. Detection of the heat sink
The detection is carried out every other second by taking in the voltage of the thermistor at A/D (PORT 31).
2. According to the temperature detected, the following operation will be executed:
31 pin 0 to 0.1V 0.1V to 2.4V 2.6V to 2.8V 2.8V to 3.4V 3.4V to 4.1V 4.1V <5 5 to 122(60°C) (70°C)134 (75°C)145 (90°C)174 (115°C)210 15 pin L L H L L L 25 pin L L L H H H 64,66,67 pin L H H H H L L H H H H L 19 pin
THRMO DCT Set voltage of A/D FAN START FAN MAX SP RELAY AMUTE
Display
"THDCT NG" flashes for 5 seconds.
"HEAT UP" flashes for 5 seconds at 20-sec intervals. "OVERHEAT" flashes.
· If you wish to switch FAN START from "H" to "L" and FAN MAX from "L" to "H," first set FAN START to "L," then after 100 µs, set FAN MAX to "H." · While "OVERHEAT" is flashing, only the POWER key is functional.
3. FAN operation
· Once the fan starts rotating, it continues to rotate at the same speed until the temperature falls to 65°C. · Once the fan starts rotating, it continues to rotate for at least 20 seconds even after the temperature falls to the above-mentioned level.
4. Detection of abnormalities in the fan
· If any abnormality is detected in the fan 5 seconds after it starts rotating at high speed, and if H (abnormal) is indicated for the FANDCT connector, "FAN STOP" is displayed for 5 seconds, then the power is turned off. · While "FAN STOP" is displayed, AMUTE is on, and RELAY is off. · While "FAN STOP" is displayed, only the POWER key is functional. · While the fan is rotating at low speed, abnormality detection is not carried out.
5. Abnormality in the thermistor
If an abnormality (A/D voltage: 0.1 V or less) is detected in the thermistor, "THDCT NG" is displayed for 5 seconds, then the power is turned off.

7.1.4 Specifications of Speaker Detection
1. Purposes
Whether the speakers are connected or not is automatically detected, and settings appropriate for the detected speakers are made to allow you to easily play surround-sound without making cumbersome speaker settings.
2. Method of detecting speakers
Whether a center speaker and/or subwoofer is connected or not is detected 600 ms after the power is turned on. < Detection of the center speaker > The microcomputer sends a detection signal and after 10 ms will read the logic of the responding signal to judge whether the speaker is connected or not. The response signal will be read at A/D. A voltage of 3.5 V or more is judged as no speaker connected. The response signals at A/D are read every 2 ms, and if the same results (less or more than 3.5 V) are obtained, the detection result is considered correct. If a different result is obtained for the second detection, a third detection is carried out, and the two results that agree will outvote the other. If detection fails three times, then it is judged that no center speaker is connected. < Detection of the subwoofer > The logic of the signal from the phono jack with a switch is read by the microcomputer to judge whether the speaker is connected or not. The signals are read every 1 ms, and if the same results are obtained, the detection result is considered correct. If a different result is obtained for the second detection, a third detection is carried out, and the two results that agree will outvote the other. If detection fails three times, then it is judged that no subwoofer is connected.
3. Speaker settings
According to the results of the detection, speaker settings are made as follows: Results of the Detections
Center SP Sub-woofer Connected Connected Connected Not connected Not connected Connected Not connected Not connected Front SP Low High Low High
Speaker Settings
Center SP Surround SP Low Low Low Low Not connected Low Not connected Low Subwoofer ON OFF ON OFF
4. User's settings
In Setup mode, more detailed speaker settings are available. Once the user's settings are made, those settings have priority. However, if the configuration of connected speakers has changed, then the detection results become valid and have priority over the user's settings until new user's settings are made.
