When operating using the internal L-band receiver as the differential source, the RX
400p receiver indicates the OmniSTAR DGPS lock status in the upper right corner of
the display. The lock symbol, illustrated in Figure 4-5, remains in the ‘No L-band’
DGPS Lock state until the receiver has acquired the DGPS satellite transmission at
which point the symbol changes to the ‘L-band Lock’ icon. The L-band DGPS
receiver will lock to the satellite signal although a valid subscription is not present
within the receiver in order to provide the facility to subscribe the receiver over the
air.

Note - When using corrections from the OmniSTAR service, the GPS output of
the RX 400p will not be differentially corrected until lock has been attained on
an OmniSTAR broadcast with a subscribed receiver.
