4. Operation
• Basically, operation is the same as the NORMAL MODE.
However, the following display will be indicated when function is changed to show that the TEST MODE is in operation.

LINE3 (SCART IN)
[Only for models without DSP]
• When function is switched to LINE, SURROUND mode will switch to X-STEREO (5CH STEREO) just for the TEST
MODE. (NORMAL MODE: 2CH STEREO)
At this point, sound checking can't be done using HP.
(HP operation cannot be guaranteed for X-STEREO (5CH STEREO))
All functions, other than LINE can be used for sound checking using HP.
C
[Models with DSP]
• Change the SURROUND mode to X-STEREO (5 ch STEREO) mode for multi CH output.
5. Errors
• BREAKDOWN CATEGORY: Depends on the error displayed during POWER ON.
P R T C T E
Protect circuit is operating.
1. Depending on the different power supply abnormalities, V+12, V+3SUB, V+3R3, V+6R8, SW+5 short-circuit occured or
D
V+12, V+3SUB, V+3R3, V+6R8, SW+5 has exceeded the stipulated standardized values.
2. In the system microP (AYW7271, AYW7270) somewhere, the XPROTECT(54Pin) line has either shorted to ground or
has been disconnected.
D V D P R T C T
Abnormal DVD.
1. Depending on the power supply abnormalities, V+6R5, V+5V, V+3R3 short-circuit occured or V+6R8, V+5V, V+3 has
exceeded the stipulated standardized values.
2. In the system microP (AYW7271, AYW7270) somewhere, the VDET line has either short to ground or disconnected.
E E P E R R

1. Communication line to the EEPROM could either be disconnected or short.
2. The EEPROM IC itself could be faulty.

• If error display does not come on again when POWER ON in the NORMAL MODE, this could mean that the speaker
terminal is short.
• If error display comes on, the following conditions are some possibilities:
1. In the AMP ASSY, either one or more of the digital amp IC has broken down.
2. Short-circuit occurred somewhere between the faulty IC(s) and speaker terminal.
3. The XSD SHUTDOWN (71Pin) line has either short to ground or disconnected somewhere between the faulty digital
amp IC and system microP (AYW7271, AYW7270).
