Nokia 31 User Manual page 14

To find the best installation location, you can use the Intensity of Field strength (IoF) function
through the terminal's light indicators (LEDs) to find the strongest signal (see "Signal Strength"
on page 17). For more detailed information on placing the terminal, refer to the information at
www.americas.forum.nokia.com.
Note: All radio transmitting devices send signals which may cause interference in
different electronic devices ( PC, television etc.). To avoid interference, place the
terminal as far as possible from other electronic devices.

The Nokia 31 terminal is equipped with an
efficient internal dual-band antenna;
however, depending on the installation
location and surrounding materials, the
signal strength reaching the Nokia 31
terminal may not be sufficient.
The Nokia 31 terminal has an external
antenna connector which allows you to
connect an external antenna adapter (XRM-
1). The adapter allows you to connect an external GSM antenna (with standard FME connector)
and improve signal reception. Once the external antenna is connected, the internal antenna of the
Nokia 31 terminal is not in use.
In order to properly fit the antenna cable adapter to the Nokia 31 terminal, you need to cut out a
small piece of the terminal cover which normally covers the external antenna connector.
