Powering On/Off
The On/Off button is used to turn your Wireless Home Phone Base
off when

wall outlet.
To use the On/Off button on your Wireless Home Phone Base, press
and hold the button for two (2) seconds to turn power off or until
the Battery and Signal Strength indicator lights turn off (Power light
remains on when connected to an AC power source). To turn the
Wireless Home Phone Base back on, press and hold the button for
two (2) seconds or until the Battery and Signal Indicator lights turn on.
AT&T 3G MicroCell™
