Ai the bottom of the beacon receiver field, a sta­
tus message will constantly keep you informed of
DGPS activity:
• A ‘tuning’ message will be displayed while a
heacon signal is being tuned.
• Once the beacon signal has been tuned, the
status message will display a ‘receiving’
message.
• If a beacon signal is tuned and no correc­
tions are being received, a ‘no data’ message
will be displayed.
• If a beacon signal cannot be tuned, a ‘no
status’ message will be displayed.
The GPS 120 will also display alert messages
concerning DGPS operation through the message
page. Three DGPS messages may appear:
No DGPS Position indicates that not
enough data is available to compute DGPS
position.
No KTCM Input indicates that the beacon
receiver is not properly connected or the
baud rates do not match.
RTCM Input Failed indicates that DGPS
data was being received but has been lost.
