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.

7

Installing the SIM Card and the Battery

1. Remove the cover from the battery compartment.

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.

8

 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.

Turning on Your Device

by a wall switch.
Insert the small end of the power cord into the Power Input port on the
back of your Wireless Home Phone Base.
Slide the On/Off switch to On position.

Checking the Wireless Signal

1. Raise antenna to an upright position.

9

2. Confirm signal strength light is green for optimal performance.

NOTE: If you do not see a green light (signal strength), you may want
to choose an alternate installation location.

Connecting the Device to a Phone

1. Unplug your phone from the wall jack.

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

IMPORTANT: DO NOT plug the Wireless Home Phone Base into a
wall jack.

NOTE:

 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.

Safety Notes

 Keep the device and the external antenna at least 20 cm from

persons.

 Disconnect external power supply and do not use the device

during a thunderstorm.

 Some electronic devices are susceptible to electromagnetic

interference sent by the device if inadequately shielded; Try to
use the device at least 2.5 meters away from TV sets, radio and
other automated office equipment so as to avoid
electromagnetic interference.

 Turn off the device in the hospital.
 Do not use the device on board and aircrafts.
 Operating of the device may interfere with medical devices like

hearing aids and pacemakers. Consult a physician or the
manufacturer of the medical device before using.

 Be aware of the usage limitation when using the device at

places such as oil warehouses or chemical factories, where
there are explosive gases or explosive products being
processed, because even if your terminal is in idle state, it still
transmits radio frequency (RF) energy.

 Do not touch the antenna while calling.
 Keep the antenna free from obstructions and position the

antenna straight up. This will ensure best call quality.

 Please put the device on the safe place. The device may cause

20

injury if used as a toy by children.

approved by vendor. Using any unapproved accessories may

affect your device’s performance, damage your terminal or even

cause danger to your body and violate related national
regulations about telecom terminals.

 As the device can produce electromagnetic field, do not place it

near magnetic items such as computer disks.

 Do not expose the device to direct sunlight or store it in hot

areas. High temperatures can shorten the life of electronic
devices.

 Prevent liquid from leaking into the device.
 Do not attempt to disassemble the device by yourself. Non-
