1.31.2 How to measure range with the variable range marker (VRM)
There are two VRMs, No. 1 and No. 2, which appear as dashed rings so that you can
distinguish them from the fixed range rings. The two VRMs can be distinguished from
each other by the different lengths of their dashes; the dashes on the No. 2 VRM are
longer.
There are two methods for measuring range with the VRMs, using the VRM key and
on-screen menu box operation.
Using the VRM key
1. Press the VRM key to display the VRM boxes. Press the VRM key again to switch
between active VRMs. The currently active VRM marker is displayed as shown in
the figure.
2. Rotate the VRM control knob to align the active VRM with the inner edge of the
target, then read the distance at the lower right of the screen. The VRM reads
"0.66NM".
Each VRM remains at the same geographical distance when you operate the
RANGE key or the [RANGE] box. This means that the apparent radius of the VRM
ring changes in proportion to the selected range scale.
3. Press and hold the VRM key to erase the selected VRM.
VRM range marker hides as marker indicated condition.
• Both of VRM1 and VRM2 indicated and VRM1 (or 2) is activated: VRM2 (or 1)
• VRM1 (or VRM2) only indicated: VRM1 (or 2)
