Notes:
After the Residential Gateway is successfully registered on the network, the

POWER, US/DS, and ONLINE LEDs illuminate continuously to indicate that the
Residential Gateway is active and fully operational.
The high-speed data operation is disabled when operating on battery power;

only the telephone service (if available on this model) is active when operating
on battery power.
LEDs may behave differently when the Residential Gateway is running on

battery power (without AC power). Most LEDs are disabled if the unit is
operating on battery power. In this mode, the POWER LED blinks to indicate
that the unit is operating under battery power.
The Residential Gateway should only run on battery power when AC power has

failed. If the POWER LED indicates that the unit is running on battery power,
but the AC power has not failed, verify that the power cord is plugged into a
working AC outlet.
