Device Installation
Before You Begin
Your device works exclusively with the AT&T cellular network and
DOES NOT use your home’s phone wall jacks.
Your device should be located:
Where you have a strong cellular signal from a cell tower,
typically near a window or outside wall. Signal strength may vary
in different parts of your home.
Near an electrical wall outlet.
Select which phone(s) you will use with the Wireless Home
Phone Base:
• A cordless phone system with multiple handsets should be used
to place phones throughout your home.
• If using an existing phone, unplug it from the wall jack.

2. Follow the step in the following figure to install the SIM card.
3. Place the battery in the battery slot and replace the battery
cover.
NOTES:
The system will stop charging the battery when the ambient
temperature is outside of the temperature range allowed for
charging (0 °C ~ 55 °C).
When the power adapter is connected, the battery will
automatically be charged.
When fully charged, the battery will automatically stop charging.

Remove the battery if the device will be unused for a long period.
The battery is intended for backup purposes only (in the event of
a power failure).
The device takes about 5 hours to charge fully. The charge time
may be impacted by environmental factors.

2. Plug your phone into the “Phone 1”port on the Wireless Home
Phone Base, using your existing phone cable or included phone
cable.

wall jack.

The “Phone 2” port can be used to connect an additional phone.
This port uses the same telephone number as the “Phone 1” port.

10
Put the device at least 2.5 meters away from the connected
phone, TV sets, radio and other electronic devices to avoid
electromagnetic interference.
Place a Test Call
1. Place a test call from your connected home phone. Before making
a call，Make sure to use 10-digit dialing even for local calls.
2. For best results, place the cordless phone base at least 12 inches
from the Wireless Home Phone Base. Lift the handset of your
home phone, enter the telephone number
Note: Keep your cordless phone plugged into a power outlet.
