Important Information
E911 Service
For emergency calls, you may have to provide your location address
to the 911 operator.
Power Outages
The Wireless Home Phone base has a back-up battery in the event
of a power outage with talk time of up to three and a half (3.5) hours
depending on environmental factors. However, a landline phone
requiring separate electric power to operate (e.g., cordless phones)
connected to a Wireless Home Phone base will not place or receive
calls (including 911 calls) during a power outage.
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
sliding the On/Off switch off and on.
Device Compatibility
The Wireless Home Phone base is not compatible with wireless
messaging services, home security systems, fax service, medical alert
systems, medical monitoring systems, credit card machines, IP/PBX
Phone systems, or dial-up Internet service. May not be compatible
with your DVR/Satellite systems, please check with your provider. DSL
customers should contact their provider before transferring a phone
number to ensure uninterrupted DSL Internet service.
The Wireless Home Phone base 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 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 sufficient
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 qualified licensed electrician is highly
recommended. Improper installation may result in phone equipment
damage or even a fire.
