E911 Service
For emergency calls, you may have to provide your location address to the 911 operator.
Power Outages
The AT&T Wireless Internet device has a backup battery, for use in the event of a
power outage, with talk time of approximately 150 minutes and standby time of
approximately 27 hours (depending on environmental factors). In the event of a
power outage (commercial power no longer available), the AT&T Wireless Internet
device will automatically begin using the backup battery, provided there is sucient
battery charge le. If there is no battery charge at the time of the power outage, the
device will not be operable.
To make calls using your backup battery, you must plug a corded phone or landline
phone into one of the “Phone” ports on the AT&T Wireless Internet device.
The AT&T Wireless Internet device will disable Wi-Fi to conserve power while using
the backup battery when there are no devices connected. To re-enable Wi-Fi while
using the backup battery, press the WPS button. Or, if power is available, plug the
AT&T Wireless Internet device into an electrical wall outlet to restore Wi-Fi. Please
allow at least one minute for the Wi-Fi function to restore.
If you experience a power outage and your backup battery is fully depleted, it will be
necessary to restart your device when power is restored by sliding the On/O switch
to the ON position; the Power light will turn solid green.
Backup Battery
A new backup battery should last for approximately ve (5) years, but the life of any
backup battery can be adversely aected by environmental conditions like moisture
and heat. To get the longest service from your backup battery, do not place the AT&T
Wireless Internet device in direct sunlight or in wet or extremely cold environments.
