Quick Start Guide
Information about the optional outdoor antenna
W
Wall duct:
To connect the Gigaset SX686 WiMAX to the outdoor antenna, the antenna cable must
be fed through the wall to the outside of the building. It must be possible to make a suit-
able wall or window duct at or near the location of the Gigaset SX686 WiMAX.
Setting up the antenna mast:
There should not be any obstructions (walls, trees etc.) in front of the antenna.
The best results will be obtained if the out-
door antenna is in sight of the WiMAX base
station (cf. Fig. 1).
If a line of sight is not possible, you can
reflect the radio waves off neighbouring
buildings. To do this, direct the antenna at
the building it is to reflect off and not at the
base station (cf. Fig. 2).

The outdoor antenna must be installed and put into service by a qualified
electrician.
ì
Only commence the outdoor work once you have taken all the neces-
sary steps to make the location safe.
Be sure to observe the safety instructions.
