Possible cause and solutions
The SE680 WiMAX modem is not connected to the
mains.
Check if the indoor unit is connected correctly.
Check if the power socket is live.
The SE680 WiMAX modem is not registered to a base
station.
Check the cable connections. If necessary, charge
a qualified electrician to check the installation.
The SE680 WiMAX modem is not ready for use.
The device may be too hot. In this case, the integrated
overheating protector prevents the SE680 WiMAX
modem from being damaged. If the temperature rises,
the SE680 WiMAX automatically reduces data transfer
to a minimum. When the temperature exceeds the crit-
ical value, the SE680 WiMAX modem switches itself
off.
Wait until the SE680 WiMAX modem has cooled
down.
Check the device status of your SE680 WiMAX
modem, see chapter "Device status" on page 36.
If the SE680 WiMAX modem does not work after
the device has been restarted, please contact your
provider/service technician.
