Status will tell you whether the correction data is being decoded is
error free or not. Normally, Status will indicate either DGPS mode OfT.
DGPS OK, Tracking or Searching (Automatic search mode) or No
Lock (Manual tuning mode). DGPS OK indicates that RTCM SC-104
DGPS corrections are being received without errors within the Age
Limit set in CFGl DGPS. These information originates fromthe MX421 B
beacon receiver. Searching indicates that the beacon receiver is search-
ing for the appropriate frequency and/or" modulation of the beacon
transmitter in automatic search mode. No lock indicates that the bea-
con receiver is not receiving DGPS corrections from the selected sta-
tion in manual tuning mode. You might see the label Tracking, which
indicates that a MSK beacon signal is present but DGPS corrections
are not being received. This is usually caused by high noise on the
beacon receiver or external device.
If you press the E key, you can select between Automatic beacon
search mode, Manual beacon tuning mode, or Qff. When the receiver
is in the Manual tuning mode, you can use the cursor key to scroll
down into the large window below Station Selection and edit the
Reference Station name. The name you enter will always be associ-
ated with the frequency to which you programmed the receiver. If you
move to another region that uses a frequency and name you previ-
ously entered, the receiver will display the previously entered name.
You can enter a new name for any manually tuned frequency at any
time.
