You have just taken an HD (horizontal distance)
measurement to your fence, or whatever target you
chose. Each of the basic measurements operates
in essentially the same simple way—power on, aim,
and fire—except that you sometimes have a couple
of other considerations.
First, the screen must be displaying the indicator for
the measurement you want to take: HD for
horizontal distance, SD for slope distance, VD for
vertical distance, INC for inclination, etc. If the
correct indicator isn't showing, press Forward until
it is.
Second, if you are using a red dot sighting scope,
the scope aiming dot may turn itself off after about
15 seconds of inactivity, as a power conservation
strategy. If the red dot isn't showing, press Fire to
turn it back on. See Power Conservation Intervals,
later in this section.
