PLOT Screen

The following operations can be made on the PLOT screen.
4.4.1.1

Setting the Horizontal Scale Range

The term range means the horizontal length on the PLOT screen. In other words, the distance between the
leftmost and rightmost end of the PLOT screen will be 5 nm if the range is set to 5 nm. The ranges of 1, 2, 5, 10,
20, 50 and 100 nm are available, which can be selected by pressing either the INC or DEC key.
When the INC key is pressed the range will increase.
When the DEC key is pressed the range will decrease.
4.4.1.2

Setting the Plot Interval

The equipment can store a maximum of 300 points of tracked positions.
The memory continues to store the tracked points at a preset interval, and the latest 300 tracked point data
are maintained at any time. This means that the old position data will be erased in the chronological order if the
tracked position data has exceeded 300 points.
Set the storage interval with
Waypoint mark
Course (magnetic bearing)
or key (scroll key).
