5. POSITION
When position data is received from EPFS, INPUT TYPE is set to AUTO. The
receivable IEC-61162-1 and NMEA (Ver-2.0 or above) sentences are GGA>RMC>GLL
(position) and ZDA (time).
The position data input by MANUAL setting has higher priority than the one input by
AUTO setting.
"Invalid" position data is not received.
The position data is used in Distress, Individual and Position Call messages. The data is
automatically erased and "Warning: Update position" message appears when it is not
updated for 23.5 hours. EPFS error message is displayed and the alarm sound is
released when EPFS data is interrupted for one minute.
