How to use the VRM, time cursor

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.
