Important Information

E911 Service

911 services are supported just as they are on any wireless device. You should expect to provide your home address to the emergency response center responsible for sending first responders (e.g., police, medical assistance, or fire) 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.

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 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.
