press the PTT on the mic and talk to the calling ship(s).

7.8.2 Position Request
Advancements in DSC have made it possible to poll the location of another
vessel and show the position of that vessel on the display of the MATRIX.
Standard Horizon has taken this feature one step further, if any Standard
Horizon GPS is connected to the MATRIX, the polled position of the vessel
is shown on the display of the GPS chart plotter making it easy to navigate
to the location of the polled vessel. This is a great feature for anyone want-
ing to know the position of another vessel. For example you buddy that is
catching fish, or finding the location of a person you are cruising with.
NOTE
The other vessel must have an operating GPS receiver connected to its
DSC transceiver and must not have its transceiver set to deny position
requests. (Refer the section 7.9 to enter information into the individual
directory).
