Plug the cable connector and tighten the flange lightly, by hand.
Do NOT use a spanner or screw key, which could damage the
antenna connectors!
The external antennas must be installed in a place with a good
strength of the GSM signal. The antenna has vertical polarization; it
must be placed in vertical or horizontal position, depending of the
local field condition.
If the SIM cards used are for different GSM operators, you may need
to place each antenna in a location with maximum strength of the
received signal from the respective GSM carrier.
MobiLink ISDN 2 GSM and its antennas must be located as far as
possible from equipment that is sensitive to electromagnetic
interferences (radios, audio or video appliances, computer monitor,
TV receivers etc). If you place the MobiLink interface or its antennas
too near radio, TV, or other sensitive appliances, their operation could
be affected.
Note1:
The antennas of the MobiLink ISDN 2 GSM interface
sends out RF energy so they should NOT be placed
very close to people. Since the GSM interface transmits
for longer periods of time, being used by several people
(most of the calls of local subscribers are routed through
it) the radiation will be accordingly higher than for a cell-
phone used only infrequently, by a single person.
Note2:
Remember to connect the antennas before
powering up MobiLink, to avoid damage to the
transmitters of the GSM modules
