GSM400 installation recommendations
The GSM400 gateway must be installed in a location where the radio
signal allows for using the GSM system.
It is advisable to leave plenty of space around the gateway for
maintenance operations.
Do not install the GSM400 gateway outdoors, since it lacks protection
devices against weather conditions that can damage the gateway (water,
humidity, etc.).
Do not install the GSM400 gateway near electronic (radio or TV sets,
Personal Computers, wired radio systems, etc.) or magnetic (credit
cards, floppy disks, etc.) devices that could be subjected to RF
interference from the module: recommended distance from the antenna
is min. 2.5 m.
Do not install the GSM400 gateway near medical devices. Its operation
may cause damage to hearing aids or pacemakers.
Always make sure that the device operation is permitted in the place of
installation (i.e. installation is not allowed in hospitals, airplanes, etc.).
