Many electrical and mechanical parts in the appliance have special safety related character istics. 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 par ts which have these special safety character istics are identified in this Service Manual. Electr ical 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 infor mation, always consult the current PIONEER Service Manual. A subscription to, or additional copies of, PIONEER Ser vice Manual may be obtained at a nominal charge from PIONEER.

NOTES:
Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). x RD1/4PU 1 J 561 47k RD1/4PU 3 J 47 x 473 0.5 RN2H R K RRS1P 1 R 0 K 1R0 Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k 562 x 5621 RN1/4PC F

1 Lights to indicate the type of input signal assigned for the current component: AUTO Lights when AUTO signal select is on. SB Depending on the source, this lights when
a signal with surround back channel encoding is detected.
12 SIGNAL SELECT indicators
8 ATT Lights when INPUT ATT is used to attenuate (reduce) the level of the analog input signal. 9 SLEEP Lights when the receiver is in sleep mode. 10 Tuner indicators MONO Lights when the mono mode is set using the MPX button. STEREO Lights when a stereo FM broadcast is being received in auto stereo mode. TUNED Lights when a broadcast is being received. 11 Speaker indicator Shows if the speaker system is on or not. SP A means the speakers are switched on. SP means the headphones are connected. 12 Character display 13 EON EON lights when the EON mode is set, and flashes during reception of an EON broadcast. The indicator lights when the current station carries the EON service. RDS Lights when an RDS broadcast is received. 14 ADV.SURR. (Advanced Surround) Lights when one of the Advanced Surround modes has been selected. 15
16 MIDNIGHT Lights during Midnight listening. 17
DIGITAL Lights when a digital audio signal is detected. 2 DIGITAL Lights when a Dolby Digital encoded signal is detected. ANALOG Lights when an analog signal is detected. DTS Lights when a source with DTS encoded audio signals is detected.
2 When the STANDARD mode of the receiver is on, this lights to indicate decoding of a DTS multichannel signal.
DIGITAL When the STANDARD mode of the receiver is on, this lights to indicate decoding of a Dolby Digital multichannel signal. PRO LOGIC II When the (STANDARD) Pro Logic II mode of the receiver is on, 2 PRO LOGIC II lights to indicate Pro Logic II decoding.
5 VIR.SB Lights during Virtual surround back processing. 6 DIRECT Lights when source direct playback is in use. Direct playback bypasses the tone controls and channel levels for the most accurate reproduction of a source. 7
