2.6 Connecting the antenna
Attention!
Do NOT connect the metallic parts of the GSM antenna connector directly or
indirectly to the protective ground, because this may damage the module!
Connect the GSM antenna to the FME-M socket. The module comes with an antenna which
provides good transmission under normal reception circumstances. In case of experiencing
signal strength problems or/and wave interference (fading), use another (directed) type of
antenna or find a more suitable mounting place for the antenna.
2.7 Installation environment
Before installing the module, verify the GSM signal strength with your mobile phone. It may
happen that the signal strength is not sufficient in the desired mounting place. In this case the
planned installation place can be changed before mounting the device.
Do not mount the unit:
● in places where it could be affected by strong electromagnetic disturbances (e.g. in the
vicinity of electric motors, high voltage, etc.)
● in wet places or places with high degree of humidity
