When the procedure completes, the height
calculation is showing in the middle of the screen,
and the HD indicator is blinking, signifying that the
instrument is prepared to take a horizontal distance
measurement of
another target. At this point, you have several
options:
•
Pressing Forward downloads the height
measurement you just took.
•
Pressing Fire takes the horizontal distance
measurement for another HT procedure.
•
Pressing Back backs up so you can retake one
or more measurements. Note that the indicators
do not blink in this instance. Any measurement
you retake affects the final height calculation.
To clear the HD measurement, long-press Back.
Multiple short presses back you out to the main
display level (which also clears the measurement).
