If Garmin DGPS or RTCM In/NMEA Out format is selected,
additional fields are provided to control a Garmin differential
beacon receiver directly from your GPSMAP 182/182C. The

can enter the beacon frequency and bit rate on the unit and the
information is used to tune the beacon receiver.
To have the unit automatically scan for a frequency:
1. With the unit set to Garmin DGPS or RTCM In/NMEA Out,
use the ROCKER to highlight the Beacon field, and press
ENTER.
2. Highlight Scan, and press ENTER. The numbers in the
Frequency field change as the unit scans from 284 kHz to
325 kHz, 200 bit rate, then 100 at 6-second intervals.
