CHAPTER 5
TROUBLESHOOTING
If you are encountering problems with using your APERIO system, please consult the following
checklist initially and perform only the specific remedy for a particular symptom. If the remedy
does not resolve your problem, please contact our Customer Service team to assist you further.
There are no user-serviceable parts inside, and any attempt at repair will invalidate the
warranty.
SYMPTOM
REMEDY
Error / Fault message on
screen
Read the message error / fault on your screen and
follow the appropriate instructions.
No sound via analog
connection
First check whether the analog/digital source selector is in the
analog position. If it is, then check that the Hi/Low rear panel
selector switch is in the appropriate position. If it is, then check
your source component to ensure it is operating correctly (is the
volume set to mute on a portable audio player, for example?).
No sound via S/PDIF digital input
First check whether the analog/digital source selector is in the
S/PDIF position. If it is, then check whether the S/ PDIF digital
output of your source has NOT been turned off via a menu
function. If not, try a different S/PDIF cable to eliminate
breakages/connection issues.
No sound via USB input
First check whether the analog/digital source selector is in the
USB position. If it is, check whether the appropriate USB driver
has been selected on your computer and in your playback
software. Check also whether the output has been muted
within your playback software.
Stuttering/glitching in USB
playback
Is the USB connection made via a USB hub? We have found
that some inexpensive or poor quality hubs can introduce
playback issues. Try connecting the APERIO directly to your
computer. Very long USB cables (> 2 meter) and some poor
quality USB cables can also compromise USB connectivity, and
should be avoided. If no hub is used, check the activity
level/number of open programs on your computer, it could be
that something else needs computer resources which
interrupts playback.
No sound via Networking input
First check whether the analogue/digital source selector is in
the Networking position. If it is, then check that the ethernet
cable is properly connected. Check that your sound source can
see the APERIO as a DLNA client. If possible, check also that the
APERIO has been assigned an IP address by your DHCP server
and that the device can be pinged. Check whether your DLNA
source is correctly streaming a single to the APERIO. Check
also whether the output has been muted within your playback
software
