SERVICE MODE
SERVICE TEST MODE
1. Conditions for Service Test
Mode
# During Service Test mode, emergency shutdown will not be performed even if failure as shown below occurs (it is ignored).
# During Normal mode, even after emergency shutdown caused by detection of failure shown below, the unit can be turned on immediately, without waiting 1 minute after shutdown.
# During Service Test mode, emergency shutdown will not be performed even if failure as shown below occurs (it is ignored).
# During Normal mode, even after emergency shutdown caused by detection of failure shown below, the unit can be turned on immediately, without waiting 1 minute after shutdown.
2. How to Enter Test Mode
# Press the "ESC" key then "+10" key of Service Remote Control unit (GGF1381). The unit is turned on in Test mode.
# The initial FUNCTION setting is iPod.
# (XW-NAS3 model) Depending on the conditions of the last power off before entering the Test mode, the POWER ON LED flashes in the pattern shown below in 4-second periods.
Note: In the following patterns, a high state denotes lit and a low state denotes unlit.
# (XW-NAS5 model) After entering the Test mode, the 7-segment LEDs are lit as shown below, depending on the conditions of the last power off before entering the Test mode.

[After normal power-off]
The LED is lit then unlit for 2 seconds.
The LED is lit then unlit for 2 seconds.
[After shutdown caused by detection of an
abnormally high temperature in the XOTW D-AMP] Error 2
After the LED flashes twice at intervals of 0.25 sec, it goes dark.
After the LED flashes twice at intervals of 0.25 sec, it goes dark.
[After shutdown caused by detection of excess
current in the SHUTDOWN D-AMP] Error 3
After the LED flashes 3 times at intervals of 0.25 sec, it goes dark.
After the LED flashes 3 times at intervals of 0.25 sec, it goes dark.
[After shutdown caused by failure in the
EEPROM] Error 6
After the LED flashes 6 times at intervals of 0.25 sec, it goes dark.
After the LED flashes 6 times at intervals of 0.25 sec, it goes dark.
Notes:
# To exit Test mode, turn the unit off or unplug the AC power cord.
# When exiting Test mode, only the RAMs related with the above errors will be initialized.
(The RAMs that can be accessed by a user for settings will not be initialized.)

Operation during Test mode
Basically, the unit operates in the same way as in Normal mode.

Description of errors
# Errors are classified into the following types and are indicated by error indications when the unit is turned on.
[After a power error is detected] Error 1
# A power error was detected.
1. The voltage at the SW9V, SW5V, SW3.3V, or EV3.3V power supply unit exceeds the specified value because of an error.
2. The line to XDC_PRO Pin No.34 in the system control computer is short-circuited with ground or broken.
[After shutdown caused by detection of abnormally high temperature in the XOTW D-AMP] Error 2
# If “Err 2” is not displayed when the unit is turned on in Normal mode next time, this does not constitute an error. (A temporary temperature rise is suspected. Use the unit at a lower volume.)
# If “Err 2” is displayed again, the following causes are suspected:
1. The digital amp IC in the NSA DAMP Assy is in failure.
2. The XOTW line somewhere between the digital amp IC and the system control computer is short-circuited with ground or broken.
[After shutdown caused by detection of excess current in the XSHUTDOWN PCONFIG D-AMP] Error 3
# Disconnect the speakers then turn on the unit again. If the error indication persists, the following causes are suspected:
1. The digital amp IC in the NSA DAMP Assy is in failure. (DC is generated between + and – of the AMP BTL output.
2. An error was generated in a circuit located on the way to the XSHUTDOWN PCONFIG circuit.
3. Dirt may be attached around the AMP outputs.
[After shutdown caused by failure in the EEPROM] Error 6
1. The communication line to the EEPROM is broken or short-circuited.
2. The EEPROM (IC) is defective.
