Getting to know your system
General Product Information
WHAT IS PLEXUS?
Plexus is a hard disk based music management system. The unit is fully computer controlled and
can be remotely managed, updated and diagnosed should any software fault arise. The system
provides continuous quality stereo music output and is capable of storing many thousands of
tracks. Plexus can be update via CDROM, network, ISDN or satellite.
WHAT DO I NEED TO DO?
Quite simply, nothing! Plexus is fully automated and programmed. It knows what to play, and when
to play it. This means that it is capable of putting itself into standby and then restarting again.
Plexus is fully capable of switching to different genres of music at different times of the day. The
unit is entirely self-sufficient and requires no user intervention.
Functions & Controls
IDENTIFYING TRACK AND DAYPART INFORMATION
Plexus shows every track it plays on the front LCD panel. This display also shows the current date,
time and the category of music currently being played.
CONTROL PANEL FUNCTIONS
The front panel buttons are for the use of CRE engineers should Plexus require attention. Please
avoid pressing these buttons unless asked to do so by a member of the CRE service team.
WHAT IF A FAULT ARISES?
Inevitably, faults do arise, however a few simple and basic checks can save time and costly engineer
visits. Please refer to the troubleshooting section for a list of possible problems and solutions. Our
customer support line is able to provide online support should you be unable to resolve the fault.
UPDATING VIA THE CD DRAWER
The CD drive is used to update new music onto your system. Push the button to open the tray, and
insert your CRE update CD. Be careful not to get any fingerprints on the disk. Push the button again
and the tray will close. The new music will then be copied from the CD and stored inside your Plexus
machine. Please observe the LCD panel for any further instructions. Once the update has loaded
successfully, you can remove the CD and dispose of it.

If the display screen on the Plexus is cycling through the
information, and shows the names of the songs that are
playing, it is highly likely that the fault is not with the Plexus
machine. Double check that all your amplifiers are turned on
and that the volume controls and input selection switches are
set appropriately
