If the site has a low cellular signal, it may not be possible to use the full mobile technology
without a special, high gain antenna. Such an antenna should be obtained and installed in a
higher position (the roof of the building), directed towards the base station of the mobile
network carrier, in order to get best results.
Warning!
Don’t use excessive force. Make sure the antenna is securely screwed into the RF
connectors, but do NOT use a spanner or screw key, which could damage the antenna
connector! Tighten the flange lightly, by hand.
The antennas have vertical polarization, so they should be placed in vertical or horizontal
position, depending of the local field condition.
!
Place the antennas on a safe (stable)
non-magnetic and flat area. The heavy
base of the antenna ensures that it is
secured.
The following table shows the main characteristics of the multi-band stick antennas with
magnetic base (currently supplied with the MobiLink package).

Note:
The MobiLinkIP unit and its antennas should be placed as far as possible from
appliances or office equipment that is sensitive to radio interference (microwave
ovens, copiers, TV sets, PC displays, and multimedia systems). For best results,
try to find a place of maximum signal reception for the Mobile antenna
In addition, the antenna must NOT be located near heavy-duty equipment that may
generate electromagnetic interferences, such as electric motors or heaters.

Power up
Switch the MobiLinkIP on by connecting the power supply adapter. Following a delay of
several seconds, the indicator LEDs will light up.
Remember that the adapter is the disconnection device (there is no POWER switch on
MobiLinkIP), so the 230 V
AC
socket-outlet must be installed near the equipment and must be
easily accessible.
