When a GPS receiver (NMEA0183 ver. 2.0 or 3.01) is con-
nected, steps r and t (Current position/time program-
ming) do not appear. Go to step y.
r The position information appears. Set your position (lati-
tude and longitude) data by rotating [DIAL].
• Push [16•9] or [CH/WX•DUAL•U/I/C] to move the cursor forward
or backward, respectively.
• Rotate [DIAL] to edit N; North latitude or S; South latitude when
the cursor is on the ‘N’ or ‘S’ position, and W; West longitude or
E; East longitude when the cursor is on the ‘W’ or ‘E’ position.
• Push [CLR] for 1 sec. to clear the latitude/longitude data.
• Push [CLR] to cancel and return to the DSC menu.
t After setting the position data, push [DIAL•ENTER] to set
the current UTC time. Set the current UTC time by rotating
[DIAL], then push [DIAL•ENTER].
• Push [16•9] or [CH/WX•DUAL•U/I/C] to move the cursor forward
or backward, respectively.
