Cellular Service Verification - AT&T 8300 Manual

Cellular service verification

After completing the setup of either mode of the cellular connection, it is important to determine that there is adequate
signal strength before deciding on a final installed position. Cellular coverage can vary, even over a short distance and a
bad placement of the AT&T VPN Gateway 8300 can result in substandard or even non-existent cellular service.
You can check the signal strength at site of install by pressing the "reset" button on the back while powered on with the
Cellular USB modem inserted. A paper clip or other sharp object will be required to properly depress this button.
The signal strength will be represented by a sequence of LEDs illuminated on the front panel. Up to six LEDs, starting with
the "online" light may be illuminated depending on detected strength. The signal strength will appear in this form for five
seconds. At least three LEDs of signal strength are recommended.

The unit should be installed in a location that gives optimal signal strength.
Note: After the final location has been determined by the best signal strength the AT&T VPN Gateway needs to be
rebooted in order to re-establish the cellular connection.
