Model SST-901M Spread Spectrum Radio Modem User’s Guide
1.0 Notice to United States Users
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesirable operation. In normal operation the unit and
approved antenna is positioned several feet from the user but under no circumstance should the antenna
be positioned less than 20 cm from the operator.
The user is cautioned that changes or modifications not expressly approved by Telonics could void the
user’s authority to operate the equipment. This restriction includes the use of specified antennas which
have been certified for use with the SST-901M. See Antenna Configurations section below.
2.0 Notice to Canadian Users
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and
maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio
interference to other users, the antenna type and its gain should be so chosen that the equivalent
isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
The SST-901M (IC: 4610A-SST901M) has been approved by Industry Canada to operate with the antenna
types listed below with the maximum permissible gain and required antenna impedance for each antenna
type indicated. Antenna types not included in this list, having a gain greater than the maximum gain
indicated for that type, are strictly prohibited for use with this device.
Approved Antenna Type Telonics P/N Max Gain Required Impedance
Collinear Vertical w/ ground plane CM007724-900 7.2dBi 50Ω
Collinear Vertical w/ ground plane CM008828-900 5.4dBi 50Ω
Aircraft Blade Antenna CM007462-001 4.0dBi 50Ω
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the
following two conditions: (1) this device may not cause interference, and (2) this device must accept any
interference, including interference that may cause undesired operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de
licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de
brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d'en compromettre le fonctionnement.

3.0 Hardware Setup
The SST-901M is a portable radio modem allowing field data transfer from a deployed Spread Spectrum
Unit to a portable laptop computer. Before the system will function properly, the SST-901M must be
properly connected to a laptop computer and an antenna. There are three connectors on the SST-901M.
Their function and proper connection are described below and diagrammed in figures 1 and 2:
1. RF connector: Connect this jack to the external antenna with the supplied coaxial cable assembly.
See the Antenna configurations section for more information about approved antennas and cabling.
2. USB Jack: Connect the SST-901M to the laptop computer with the supplied USB cable. The unit
derives power from the laptop via the USB cable.
3. External Power Jack (optional): The SST-901M is normally powered by the laptop via the USB cable.
When the radio link is in use, the laptop battery will be depleted much faster than normal. Laptop
battery life can be extended by connecting the optional 12V Auto Charge Cord (Telonics P/N
PS000338-001) to the external power jack. Note that the charge cord only supplies power to the SST901M – it does not supply power to the laptop computer.

The following antennas have been specifically designated and certified for use with the SST-901M. Use of
other antennas voids the user’s authority to operate the equipment.
