1.15.2 How to measure the range with a VRM
There are two VRMs, No. 1 and No. 2. The VRMs are dashed rings so that you can
identify the rings from the fixed range rings. You can identify VRM 1 from VRM 2 by
different lengths of dashes. The dashes of the No. 1 VRM are shorter than those of
the No. 2 VRM.
1. Press the VRM key to display either of the VRMs. Press the VRM key to change
the active VRM between No. 1 and No. 2. The indication of the currently active
VRM is in a rectangle.
2. Use the CursorPad to align the Variable Range Marker with the inner edge of the
target. Read the distance at the lower-right corner of the screen. Each VRM re-
mains at the same geographical distance when you operate the RANGE key. The
size of the VRM ring changes in proportion to the selected range scale.
3. Press the ENTER key to anchor the VRM.
4. To erase a VRM, press the VRM key to activate the VRM and press the CANCEL/
HL OFF key.

yards (NM&YD). The cursor range unit is also changed when the VRM unit is
changed.
