lock status in the upper right hand corner of the display. The lock

the GBX is locked to an RTCM signal, and open, when no broadcast is
available for the specified frequency and/or MSK bit rate.

corrected until lock has been attained on a valid RTCM
broadcast.
When in Gx-E mode, the beacon receiver lock indicator in the upper
right hand corner of the display is replaced with an ‘E’ indicator as
illustrated in Figure 3-4.
