Important Information

E911 Service

911 services are supported just as they are on any wireless
device. But you should expect to provide your address to the
emergency response center responsible for sending fi rst
responders (e.g., police, medical assistance, or fi re) to your
location.

Power Outages

Wireless Home Phone Base has a back-up battery with talk
time of up to three and a half (3.5) hours depending on
environmental factors. Please note you'll need a standard
corded phone that doesn't require external power to function
with the back-up battery for all calling, including 911.
If you experience a power outage and your battery is fully
depleted, it will be necessary to restart your device when power
is restored by pressing and holding the On/Off button for two
(2) seconds.

Device Compatibility

Wireless Home Phone Base does not support your home
security systems, fax machines, dial-up or DSL internet service,
DVR services, medical alert services (e.g., Life Alert), or credit
card machines. The service cannot be used to make 500, 700,
900, 976, 0+ collect, operator assisted, or dial-around calls
(e.g., 1010-XXXX).
The device does not support data and messaging services (e.g.,
texting, multimedia message services (MMS), and data tethering).

In-Home Wiring

Interconnecting to home telephone wiring is not necessary,
but is possible; however, it is not recommended unless you
possess suffi cient knowledge of electrical systems. Use with
home wiring requires the physical disconnection from other
services, including the landline coming into your home. Use of a
qualifi ed licensed electrician is highly recommended. Improper
installation may result in phone equipment damage or even a fi re.
