Method
Process After Detection Description / Remarks
"AMP DC"
("DC output from
SP term")
detection Flashing
"AMP ERR"
for 3 seconds ADVANCED
MCACC
LED
DC XDCERR
(Pin 21 of IC300)
Detect "L" 1) Muting on, speaker relay off.
2) "AMP ERR" flashing
3) Shutdown after 3 seconds.
4) "ADVANCED MCACC" LED
flashing
5) Power on is not acceptable. To detect high DC output from amplifier damage
(defect status).
A process to protect speakers (for protection of
connected external devices).
For checking, refer to "How to enter release
mode" below.
If the DC detection port become "H" for
3 seconds, the unit will returns to normal
condition automatically.
"AMP overload"
detection. N/A iPod
iPhone

LED
OL XOLERR
(Pin 13 of IC300)
Detect "L" 1) Muting on, speaker relay off.
2) Shutdown immediately.
3) "iPod iPhone iPad" LED
flashing
4) Power on is acceptable. To detect overloading (abnormal status) with
low-load driving or a short circuit of the speaker
terminals (for protection of the amplifier).
"Over Heat"
detection. Flashing
"AMP
OVERHEAT"
for 3 seconds FL OFF
LED
STMP TEMPERR5
(Pin 24 of IC300)
Detect "H"
(REDI _DET) 1) Muting on, speaker relay off,
2) "OVERHEAT" flashing
3) Shutdown after 3 seconds.
4) "FL OFF" LED flashing
5) Power on is acceptable after
1 minute. To detect overheat of inner tempareture.
"Abnormality DC
voltage of the
Digital power
supply" detection N/A iPod

LED
DERR XVDDERR
(Pin 22 of IC300)
Detect "L" 1) Muting on, speaker relay off.
2) Shutdown immediately.
3) "iPod iPhone iPad" LED flashing
4) Power on is acceptable. To detect the abnormality voltage of Digital
power supply circuit for the D-MAIN Assy.
"USB Overload"
detection "Over Current"
No Flashing N/A N/A USB ERR (VCO0)
(Pin K2 of IC9204
(DM860A))
Detect "H" 1) USB bus Power off
2) Display "Over Current" To detect the connected USB device is
overload. (over 2.1 A)
"BT Adapter
overload"
detection. "ADP
OVERLOAD"
No Flashing N/A N/A BTOL (MII_CRS)
(Pin R14 of IC9204
(DM860A))
Detect "H" 1) Adapter port power off
2) Display "ADP OVERLOAD" To detect the connected Blue Tooth Adapter
device is overload. (over 100 mA)
"HDCP of HDMI
Error"
detection Flashes "HDCP
ERROR"
for 5 seconds N/A N/A Read Register
value 1) Display "HDCP ERROR" The monitor does not support HDCP type or
is in standby mode.
(Warning indication for HDMI Simplay)
Analog POWER

LED
XPRT XPROTECT
(Pin 12 of IC300) 1) Muting on, speaker relay off.
2) Shutdown immediately.
3) "FL OFF" LED flashing
4) Power on is acceptable after
1 minute. Power-on impossible for 1 min.
"Over Heat"
detection N/A
(VOL LEVEL) N/A N/A TEMP L (TR_DET)
(Pin 11 of IC300) VOL 3 dB down After this error is detected, the system interrupts
the OVER HEAT detection for 2 minutes.
"wireless LAN
converter Over
Current" detection WLAN POW
ERR N/A N/A XWUSB ERR
(Pin 27 of IC300) WUSBPOW is set to L. To detect the connected wireless LAN converter
is overload. (over 600 mA)
"Analog Input
Over" detection "OVER" Icon
lights 1 second N/A N/A DSP firmware
Detect While the Icon lights 1 second,
when there is no ANALOG INPUT
OVER detection, the Icon stops
lighting and returns to normal
display. To detect the over-input of the analog audio to
the A/D converter.
When the Icon lights frequently, output level of
the source equipment is high and a sound is
distorted. Turn on the Analog Att switch.
During Standby mode, simultaneously press and hold the "TUNE
↓
" and "MULTI-ZONE ON/OFF" keys for 5 seconds.
Errors upon detection of abnormalities in the amp system are indicated.
