Area C indicates the time when the next COSPAS-SARSAT pulse is expected. If after one minute no
COSPAS-SARSAT pulse is received, the bar-graph-indicator is fully filled and shows the text “--:--“.
The indicator in the Area D (s. Figure 66, “D”) shows the following values:
o
Direction from the current GPS position to the position of the marked COSPAS-SARSAT
message (“GPS TB” = GPS True Bearing).
o
Distance from the current GPS position to the position of the actually marked COSPAS-
SARSAT message (the indication “km” or “NM” is adjustable in the “Setup”, s. 7.4.2.5).
o
Frequency:
By viewing an old message frequency may be other than the current frequency. In this
case the frequency is displayed in gray.
The current frequency is displayed in white. The current frequency is also displayed in
the label of the hotkey for adjusting frequency.
Note
GPS TB data can be shown only if compass and GPS are available.
The distance can be shown without connection of vessels compass if GPS is connected to DCU.

Bearing
View
This COSPAS-SARSAT bearing view allows the graphical indication of the decoded COSPAS-
SARSAT information of the selected beacon ID.
Press the hotkey “C/S Bearing” (s. Figure 64, position 2) to open the “COSPAS-SARSAT Bearing”
view.
Note
Please note that the label of the hotkey will turn to “C/S List” in order to get to the list page again.
The “C/S Bearing” page displays the following information, which corresponds to the selected beacon
ID:
The numerical bearing indication (True Bearing)
The indication of the calculated bearing as the gray arrow (“GPS Arrow”)
The calculated distance to the target
The COSPAS-SARSAT frequency
The heading of the ship indicated by the compass rose and the top triangle (here: 61°)
Corresponding number and beacon ID and
the time of the last received pulse
Pressing the “Left” and “Right” arrow buttons of the keypad switches between the older and newer
messages of the same emergency beacon.
