4.3 Changing 3D View Scale Mode and Scale Selection

The depth (z-axis) of the graph is displayed in either "TIMe" or

"DISTance" scale mode. The depth can be set to 500 or 1000

meters in the distance scale mode, or 1/1, 1/2 or 1/4 in the time

scale mode. The fraction means graph update/number of trans-

mission. "1/4," for example, means the graph is updated every

four transmissions.

These selections are made on the 3D VIEW SCALE and TIME

SCALE (or DISTANCE SCALE) lines of the BOTTOM/3D menu.

The time mode should be selected when speed data is not

being fed to the unit from navaids or speed log.
