(Optional) Installing an external antenna
In areas with poor network coverage, connect an external antenna to the device's
external antenna port. Screw the external antenna in fully, as shown in the
following figure.
Note:
Skip this section if you do not need to connect an external antenna to the
device.
Before using an external antenna, log in to the web management page
(http://192.168.1.1) and set antenna mode to external. For details, see the
help information on the web management page.
Only use the external antenna indoors.
You cannot switch between the internal antenna and the external antenna
while using a voice or data service.
(Optional) Connecting to a telephone
If you want to use the device to make voice calls, connect the device to a
telephone, as shown in the following figure.
Note:
Skip this section if you do not plan to use the device's voice services.
Radio signals can interfere with telephone call connection and quality. To
eliminate the risk of possible interference, place the telephone at least 1
meter (3.28 feet) away from the device.
Do not connect the device to the telephone wall outlet (or any Public
Switched Telephone Network), which will cause excessive heat or even
damage the device.
