On this display the characters show the selected GRI and the Secondaries
being received and used for calculations in the Signal box (prominently
featured on the page). The Master (M) station is shown first in the box. As
each Secondary signal is received it becomes listed in the box. The signals
appear in the list in the order in which they are received and not necessarily
in numerical order.
The selected GRI number appears in the top section of the box. An “A” may
appear to the right of the GRI to indicate that the 508 sensor is operating in
the automatic GRI and secondary selection mode. If the “A” is not ON, the
sensor is in the “manual” Station selection mode.
