3.10.2 Signal Status Pages

The SIGNAL STATUS displays are used to show the conditions of signal

acquisition and tracking of the attached sensors and thereby indicate the

quality of the position fix. If the NAV unit is using both a loran and GPS

sensor, the status of the sensor in use is always displayed. You may choose

GPS or Loran operation while in the normal Display modes by pressing the

key.

On this display the characters show the selected GRI and the Secondaries

being received and used for L/L 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.
