Measuring Depth, Time

The VRM functions to measure the depth, and the time cursor measures time.
1. Rotate the [ENTER] knob to shift the VRM; counterclockwise the shift it
downward, clockwise to shift it upward. You may also use the cursor pad to
shift the VRM, in which case use ▲ or ▼.
2. Use ◄ or ► on the cursor pad to shift the cross-hair cursor to measure time.
Note: If, when the range setting is over 1000 ft (m, fa, p/b), the VRM indication
and depth scale may overlap one another, shift the cross-hair cursor
slightly to show them completely. Further, when the display is shifted, the
depth scale may obscure the time indication.
