To select a 'Transfer Mode' :
If the GARMIN format is selected, highlight the 'Transfer Mode' field and press the ENTER key.
Select the desired setting (top left picture) and press the ENTER key. The 'Transfer Mode' field

To select a beacon frequency when selecting an RCTM format:
If an RTCM format is selected, additional fields are provided to control a GARMIN beacon
receiver directly from the StreetPilot. Highlight the 'Beacon' field and select the DGPS beacon you
desire from the list provided. Frequency and bit rate will be automatically entered. By selecting
'Other', you can enter the beacon frequency and bit rate on the StreetPilot and the information will
be used to tune the beacon receiver (lower left picture). For more information, refer to the Owner's
Manual for the GARMIN beacon receiver or request the GARMIN DGPS Beacon Reference Card,
Part Number: 190-00069-01 Rev. C. After selecting the desired setting, press the ENTER key.
Understanding 'Beacon Status' messages:
If an RTCM format is selected, the unit must be connected to a Beacon Receiver. While the beacon
is operating a status field keeps you informed of changes in operation. Advisory information such as
"Tuning", "No Differential GPS Position", or "Beacon Receiver Disconnected" will display in the
'Beacon Status' field. Take appropriate action as required.
