Tuning

Sialus Messoge

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.
