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.
