PCB PARTS LIST 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%). 560 Ω = 56 × 10 1 = 561 ................................................... RD1/4PU 5 6 1 J 47k Ω = 47 × 10 3 = 473 .................................................. RD1/4PU 4 7 3 J 0.5 Ω = R50 ...................................................................... RN2H Â 5 0 K 1 Ω = 1R0 .........................................................................

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: THRMO DCT Set voltage of A/D FAN START FAN MAX SP RELAY AMUTE Display 0 to 0.1V < 5 L L L L "THDCT NG" flashes for 5 seconds. 0.1V to 2.4V 5 to 122(60°C) L L H H 2.6V to 2.8V (70°C)134 – H L H H 2.8V to 3.4V (75°C)145 – L H H H 3.4V to 4.1V (90°C)174 – L H H H "HEAT UP" flashes for 5 seconds at 20-sec intervals. 4.1V – (115°C)210 – L H L L "OVERHEAT" flashes. 31 pin 15 pin 25 pin 64,66,67 pin 19 pin • 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.

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 Speaker Settings 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. 5.
