4.4 GPS/Time Setup
By default, the Ray218/Ray55 auto-detects NMEA 0183 strings and decodes
appropriate latitude/longitude position and time or COG/SOG. When position
data is available, the GPS satellite icon appears on the top line of the LCD. 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.
Manual Position
If no GPS data is available and the MMSI number has been programmed, the GPS
icon blinks and 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 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 (lat/lon) fields are set to all 9’s,
time field is set to all 8’s, and the display reverts to NO POS DATA.
Note:
The Manual Lat/Lon function is valid only when your radio is not connected to a
GPS receiver.
