Troubleshooting
Synapse SB67020 Deskset User's Guide
Probable Cause
There may be no power or
the Deskset may need to be
reset.
The Gateway is failing to
synchronize with a Deskset
configured for a different
system configuration.
The Ethernet cable is
unplugged.
There may be a problem with
the office network.
Corrective Action
See "To resolve a blank screen or device that does not

work at all:" on page
Reset the Deskset to factory defaults. Insert a pen or

paper clip into the reset hole and press for more than five
seconds.
Always disconnect the LAN cable before restoring factory

defaults (by pressing the RESET button more than five
seconds).
Ensure that one end of the Ethernet cable is plugged into

the port marked LAN on the device and that the other end
is plugged into your office LAN.
Confirm that the Ethernet port light next to the Ethernet

port is green. If it is not, unplug the cable and plug it in
again.
Check if other network devices, such as computers, are

communicating with the network. If not, then contact your
IT administrator.
