H.I. (Height of
Instrument)
The H.I. function is used to prevent elevation changes caused by move-
ment of the tripod.
When the H.I. Alert function is activated, the self-leveling accuracy
remains the same, but the self-leveling range of the Rugby is reduced.
Movement of the Rugby beyond its self-leveling range will cause an “alert
condition”. The Rugby will stop rotating and the following screen will
appear on the display:
Stop the “alert condition” by pressing the Star or Power button and reset
the function.
Check carefully the setup and elevation of the unit to determine what
has caused the alert condition. Adjust as required to the correct eleva-
tion.
The H.I. function can be turned on or off in the first setup screen.
When the H.I. function is turned on, the letters “HI” will appear in the
bottom, right part of the display.
The H.I. function becomes active 30 seconds after the unit has
completely leveled and the head starts rotating.
