6.6 GPS/Time Setup
By default, the Ray54 auto-detects NMEA strings and decodes appropriate
latitude/longitude position and time. If the GPS navigation receiver is not
connected or is not functional, a manual latitude/longitude position and UTC
time can be entered and used in the DSC distress transmitted message.
When GPS Information Not Available
If no GPS data is available, the NO GPS icon appears, POS DATA REQ is
displayed on the dot matrix display, followed by NO POS DATA. An alarm
sounds for 5 seconds or until you acknowledge by pressing any key.
The position (lat/lon) fields are set to all 9’s and time field is set to all 8’s. The
alert repeats every four hours as long as no position information has been
entered manually. If position data is entered manually but has not been
updated during the previous 23.5 hours, all the position fields are set to 9’s
and the display reverts to NO POS DATA.
Note: The Manual Lat/Lon function is valid only when your radio is not con-
nected to a GPS receiver.
