Installing Antenna (Optional)
For the FWT type that can be installed with indoor antenna, see the following
instructions for installing the antenna.
Installing Indoor Antenna
In an area where signals can be transmitted and received with good quality, you
can install an indoor antenna, as shown in Figure 4-6.
Figure 4-6 Installing an indoor antenna for the FWT
1 Make sure to place the switch of the FWT in the OFF position.
2 Align the indoor antenna with the antenna port on the FWT host in the
direction shown in Figure 4-6, and then screw the antenna, ensuring that the
connection is secure.
Viewing the receive signal strength
The FWT provides you with the function of measuring the receive signal strength,
specifically as follows:
1 Searching the signal
Power on the FWT. Wait for a while, until the received signal strength indicator
appears or the dialing tone can be heard after you pick up the handset. Five
minutes later, if there is no signal indicator or the dialing tone, please adjust the
direction of the antenna. If the antenna is moved around 360
o
and there is still no
signal indicator, it indicates that the signal condition is really bad. Move the
antenna to the direction where the dialing tone can be heard after you pick up the
handset.
