6. OPTIONS
In this section we will explain the different available options for the base station WBS-202 unit.
OMNIDIRECCIONAL ANTENNA (0A-P0360)
To implement the diversity system in the base station, it is necessary connect two more
omnidirectional antennas in the rear antenna connectors (ANT-1R and ANT-2R). These optional
omnidirectional antennas are the same that the base station front panel.
DIRECTIONAL ANTENNA (DA-P6060)
This accessory is provided with an extension 2 meter low loses coaxial cable. The antenna
must be installed on the wall pointing out the desired area and covers a focused beam of 60
degrees H by 60 degrees V. The panel antenna must be installed on the unit to cover the local
area around the unit.
7. SPECIAL OPERATIONS
In order to set-up some of the base station possibilities, the unit must be opened removing the
six screws of the unit top cover.
NOTE:
This type of operations takes place with the unit is opened; the best thing should be to carry it

the mains there are different parts of the unit that are subjected to high voltage.
CAUTION:
Protect the base station from the rain and moisture, mostly if it is open. If liquid is spilled
into the unit, disconnect it from the mains and consult a qualified service technician.
CHANGING THE MIC GAIN
