Bose FreeSpace 4400 Service Manual page 73

Retry Fault: The amplifier has tried to start
up or recover from a fault condition at least
six times. When this occurs, you will need to
place the FreeSpace
standby and then press the STANDBY
button again to clear the fault, at which time
the FreeSpace 4400 system will again try to
start up.
When this occurs you should check the
alarm history section of the Amplifier Alarm
to determine the exact fault type that trig-
gered the Retry Fault.
Input and Output Alarm History: This part of
the Error Log displays the sequence of fault
conditions where "0" is the initial fault re-
ported followed by "1-6". These occur over a
very short period of time.
Solving faults reported in the Error Log
When errors are reported in the Error Log,
you can try to solve the problem by perform-
ing one of the following actions:
• On the FreeSpace 4400 rear panel, turn
the POWER switch to OFF. Wait a few
seconds and turn the POWER switch to ON.
Then press STANDBY on the front panel.
• On the FreeSpace 4400 rear panel, turn
the POWER switch to OFF. Disconnect all
input/output signal cables. Wait a few sec-
onds and turn the POWER switch to ON.
Then press STANDBY on the front panel.
Reconnect one cable at a time and check
the Error Log.
Common Problems
Communications port error
When you receive the communications port
error dialog, the FreeSpace 4400 Installer™
software was not able to locate a FreeSpace
4400 system on the COM 1 port.
TROUBLESHOOTING
®
4400 system in
This normally occurs due to one of three
reasons:
• The PC and FreeSpace 4400 are not
connected via a "straight-wired" serial cable.
• Another software application has control of
the serial port. Applications such as the Palm
OS, or other audio applications control the
serial port while they are open. Close these
applications and click the TRY AGAIN
button.
• The FreeSpace 4400 is connected to
another communications port. If this is the
case you should select the appropriate COM
port and click the TRY AGAIN button.
No audio in zone
Note: Before dismissing the "Choose COM
port" dialog, select the COM 2 port and click
the TRY AGAIN button. Not doing this will
cause the COM 1 port to be locked. If the
port locks, you must restart your computer.
If the system is powered on and operational,
but there is no sound, check the following:
• Do the front panel LEDs indicate normal
operation?
• Is the source operating?
• Is routing correct?
• Is output gain correct?
• Is the output gain muted?
• Is cabling correct?
