The MS-900SP is a Single-Person Radio Interface
designed for vehicular or desktop use.
A single 900-series headset can be connected to the
HEADSET jack, or can be used remotely by
connecting an extension station into the
EXTENSION port.
A footswitch (FS-950) or a pushbutton station
(PBS-950) can be added to allow hands-free
transmit operation.
The MS-900SP is typically connected to a single
mobile radio through use of the proper radio cable.
Adding an RRC-950 Radio Routing Controller and
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-900SP can be powered from 12 to 24 VDC,
either supplied by a vehicle power system (using a
Setcom 25-1004 Power Cable), or by using a small
AC-to-DC power supply (Setcom 26-5007). The unit
has an internal 1 Amp ATO-type fuse, but it is
recommended that a vehicle power source also be
fused (at least 1 A).

RX Audio level is normally
set by the volume control on
the mobile radio.
