Introduction
The Toro®OSMAC®G3 Satellite combines modular flexibility, ease of use and increased programmability in a
single controller.
Modularity means flexibility. The OSMAC G3 is available from 16 to 64 stations, and can expand in 8-station
increments to meet your needs. Optional station switch capability and surge protection provide simple operation
and added security.
The intuitive OSMAC G3 user interface is easy to use and includes a back light for improved visibility in low-light
conditions, yet it is completely viewable in direct sunlight. The faceplate’s simple navigation arrows and Select
button allows for easy navigation and faster menu selection.
With 12 irrigation programs, the OSMAC G3 satellite allows programming to the station level. Discrete local and
central modes make stand-alone and central controlled operations independent from one another, while the ability
to run up to 16 stations simultaneously lets you irrigate a wide variety of landscapes.

Setting OSMAC G3 for Radio Communications
In order to send page commands to the OSMAC G3 controller, you must set and coordinate the satellite address
and the transmitting and receiving frequency with the radio system being used.
Satellite Address - Satellite address is the identification that is given to a particular satellite. In order to
communicate with individual satellites, each satellite is given a unique satellite address. When a page is sent
to that satellite address, only the intended satellite will respond and the other satellites will ignore the page
command.

Electromagnetic Compatibility
Domestic: This equipment generates and uses radio frequency energy and if not installed and used properly,
that is, in strict accordance with the manufacturer’s instructions, may cause interference to radio and television
reception. It has been type tested and found to comply with the limits for a FCC Class B computing device
in accordance with the specifications in Subpart J of Part 15 of FCC Rules, which are designed to provide
reasonable protection against such interference in a residential installation. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment does cause interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
• Reorient the receiving antenna.
•Relocate the irrigation controller with respect to the receiver.
• Move the irrigation controller away from the receiver.
• Plug the irrigation controller into a different outlet so that the irrigation controller and receiver are on different
branch circuits.
If necessary, the user should consult the dealer or an experienced radio/television technician for additional
suggestions. The user may find the following booklet prepared by the Federal Communications Commission
helpful: “How to Identify and Resolve Radio-TV Interference Problems”. This booklet is available from the U.S.
