the home with a strong wireless signal 

(3 green bars or more), typically near a 

window or outside wall.

connected to the Wireless Home Phone

working order.

cable included with the Wireless Home

position and increase the distance away 

from other electronic devices and the 

Wireless Home Phone device (including 

cordless base stations, Wi-Fi routers, 

and cell phones).

•   Voice quality may degrade with a low 

battery charge (red). Connect to an AC 

power source to recharge when power 

is available.
