Sony Ericsson G30 - Manual (Page 12)

Installation
12 Fixed Wireless Terminal: G30 and G35 models
Note: Once you have entered the PIN code for the first time, you
will not have to enter it again unless you change your SIM card.
The FWT performs this operation automatically in case of power
failure.
Network Search
After you have switched on your FWT and entered the PIN, the FWT
automatically searches for a network.
When a network is found, the Radio LED is on or flashes depending on
the GSM signal strength.
Note: If the Radio LED is off, you do not have access to the GSM
network at your present location.
Now you have prepared the FWT for wall installation. Please, follow the
instructions below for complete wall installation.
Installing the FWT on the Wall
FWT Location
The GSM signal strength available at the FWT location affects the
performance of the unit. The stronger the GSM signal, the better the FWT
performance.
Tip: Test several potential locations by moving the FWT while
looking at the Radio LED. Select the location where the Radio LED
is continuous steady, or the location with the highest amount of
flashes.
Note: Moving the FWT as little as 20 cm can affect the GSM
reception quality.
