INSTRUMENT HT. – allows the height of the unit from ground level to be entered (ie to eye-level), this is used in
the range finder and rapid fire modes. The entered instrument height is added to the VD (Vertical Distance)
calculated and displayed in this mode so VD (Vertical Distance) is the height from ground level of your
observation (not your eye level, as before).
A plus sign (+) is displayed next to the VD (Vertical Distance) to show the user that the reading is using an
instrument height, this disappears if the user has 0.00 as an instrument height.
BACK OFFSET – allows the user to include a back offset. This is the distance between the back of the eyepiece
and the receiver board. If included that offset is added while taking ranges.
