Figure 4-8 Changing Radio Frequency
The GS-450 radio modem used with the GeoSteer system provides a data link to supply RTK corrections from a Base Station
to produce repeatable sub-inch accuracy. The radio modem must be configured to the same frequency as is used on the Base
Station in order to communicate properly. Also, any time the user needs to use a different Base Station or repeater running on a
different frequency, the radio frequency on the GeoSteer must be changed to match the new one.
Note: If the GeoSteer detects a GS-900 Radio Modem installed, all screens will give the option to change and manage the
radio modem Channel. If the GeoSteer detects a GS-450 Radio Modem installed, all screens will give the option to change and
manage the radio modem Frequency. If no Radio Modem is detected, the Channel/Frequency screens will not be available.
Note: Before proceeding with the radio frequency configuration procedure, ensure the Base Station is properly installed and
operational. Also verify what Radio Modem frequency and channel spacing the Base Station has been set to. See your Base
Station Operator’s Manual for operation and installation instructions.
The Frequency screen displays the Current Frequency that the GS-450 is set to. The user has the option to:
• Change Frequency – Manually enter a new frequency and channel spacing to program into the Radio Modem.
• Use Previous – Select from a list one of the previous frequency that have been used.
Note: The Base Station channel number is usually displayed on a sticker on the Base Station receiver.
To change the frequency, follow the procedure below:
1. Obtain the radio channel number used by the Base Station.
2. From the GPS tab, press the RTK button and then highlight Frequency from the list on the left.
3. Use one of the following options to change the frequency:
