DGPS reference station information

 
SS: SS (Signal Strength) displays a numeric 
representation of field strength of the 
received signal on the selected frequency. 
The higher the number the stronger the 
received signal. (should read at least 60.) If 
noise is present at reception band width, the 
figure gets bigger. 
 
SN: SN (Signal-to-Noise) ratio displays the 
ratio between the desired signal and 
unwanted noise on the selected frequency. 
The higher the SN ratio the better the quality 
of the signal. (should read at least 21.) 
 
Note: If your equipment does not have a 

DPGS receiver, the message “NO 
DIFFERENTIAL DATA” appears when 
the BEACON INFO soft key is pressed. 
Also when connecting with the 
external beacon receiver, this 
message appears. 

 
 

The steering display provides steering 
information such as range, bearing, ETA to 
destination, course and speed. 
Press the [XTE/HIWAY] key several times to 
show the steering display.

The solid inverted triangle at the center of 
the compass shows own ship’s course. The 
hollow inverted triangle shows the bearing to 
destination waypoint. When own ship’s 
course is changed, the hollow inverted 
triangle moves with course change. 
 
Note: Course means the direction which 
own ship moves to, it is different from the 
own ship’s heading. Tide current and wind 
may affect the course.
