The Setcom MS-900SPW4 is a Wireless Radio Interface for use
with up to 7 LibMAX Series Wireless Headsets:
Radio Transmit Headsets:
CSB-900MAX (standard)
CSB-902MAX (vented)
Intercom-Only Headsets:
CSB-901MAX (standard)
CSB-905MAX (vented)
The MS-900MAX is typically connected to a single mobile radio
through use of the proper radio cable.
Adding an RRC-950 Radio Routing Controller and a
25-0108 connecting cable will allow operation with two radios. One
radio cable will be required for each radio. The RRC-950 has a
toggle switch that allows for switching TX, RX, and PTT functions
between the two radios (RX can be either summed or switched).
The MS-900MAX can be powered from 12 to 24 VDC, supplied by
a vehicle power system. The unit has an internal 1 Amp ATO-type
fuse, but it is recommended that the vehicle power source also be
fused (at least 1 A).
The system starts up as soon as power is applied.
No “pairing” is required to use headsets with the base unit, the
headsets only need to be on the same channel as the base unit
(displayed in the CHANNEL indicator).
Changing channels is accomplished by pressing the CHANNEL
SELECT button.
Typically no adjustments are required, but if transmit or receive
audio levels to and from the radio need adjustment, see page 3.

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

RX Audio level is normally set by the volume
control on the mobile radio.
If further adjustment is needed, RX LEVEL
control can be used to adjust RX volume.
MS-900MAX Controls and Adjustments
TX Audio level is normally
factory-preset to the correct
level for the radio type specified
when the MS-900MAX is
ordered.
If a different TX level is required
the TX LEVEL can be set from
0 (highest) to F (lowest) to
accommodate various radios.
Call Setcom Tech Support for
assistance if needed.
