Lock Status
The MBX-4 indicates lock status in the upper right hand corner of the
display. The lock symbol, illustrated in Figure 3-2, remains in the closed
position when the MBX-4 is locked to an RTCM signal, and open, when
no broadcast is available for the specified frequency and/or MSK bit
rate.
