CSB-9xxMAX Wireless Headset
In a typical installation the
antenna is pointed directly
upwards as shown here
(or directly downwards for
ceiling/headliner mount)
If the MS-900SPW4 must be
installed on a vertical surface, it is
recommended to “fold” the antenna
so the main shaft is vertical
To orient the antenna, loosen the
connector, place the antenna in the
desired position, then re-tighten the
connector. Once the antenna
connector is tightened, do not try to
turn the antenna
The system will work
with the antenna
oriented horizontally,
but effective range may
be somewhat reduced
