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. Instructions for operating the LiberatorMAX Series headsets can be found in the LiberatorMax Fire Users Guide 5/30/16 SBH MS-900MAX_UserGuide_REV_X2.pdf Page 1 of 5 MS-900MAX Typical Installation Connect Power Cable to DC Power Source, 12 to 24 VDC RED = +V GREEN = GND CSB-9xxMAX Wireless Headset If 2 radios are required, a Setcom RRC-950 can be connected to the RRC Jack. Refer to the RRC-950 User Guide for more information. Mount the MS-900MAX using the 4 small mounting holes or the 2 larger holes on the enclosure flanges. Mounting screws supplied by user.

(or directly downwards for ceiling/headliner mount) RC or RCB Radio Cable 464.100 TAC 1 Mobile Radio Radio Cable part number is determined by radio manufacturer, model number, and length of cable The MS-900MAX should be mounted in a location where the CHANNEL SELECT button is accessible and the CHANNEL indicator can be easily seen. 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 Page 2 of 5 MS-900MAX Controls and Adjustments NOTE: Remove top cover carefully to make sure internal cables, wiring, and ground contacts do not get damaged!
If RX LEVEL control does not provide enough adjustment range, the RX RANGE switch can be set to allow higher or lower level settings. For Factory Calibration DO NOT ADJUST MS-900MAX shown with top cover removed 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.
