PROBLEM
CORRECTIVE ACTION
The PWR light
is not on when
I turn on the
Prestige.
You might be using the wrong power adaptor.
Use the included power adaptor only. Refer to
the power specifications.
If you are using the correct power adaptor,
disconnect and re-connect the power adaptor,
and turn on the Prestige again.
If the PWR light is still not on, use a different
power outlet.
If the problem continues, contact your local
vendor.
The ALM light
is on.
The ALM light blinks once if the VDSL
connection is dropped. If the ALM light stays
on, however, contact your local vendor.
