SERIAL NUMBER
Whenever you call the network operator or service provider with questions about
your SAU-1900E, they will need the serial number of your SAU-1900E. This is printed
on the label attached to the back of the SAU-1900E on a label above a bar code (see
figure below). An ideal time to record the serial number of your SAU-1900E would be
when installing the SAU-1900E for the first time. Record the serial number in the back of
this guide, and store this guide (along with your sales receipt) in a safe place separate
from the SAU-1900E for future reference.
