Head Speeds

The Rugby can be set to any of four
different head speeds – 5, 10 , 15, or
20 rps. (300, 600, 900, 1200 rpm)
Select the head speed that provides
the best performance for your
application.
H.I. (Height of Instrument)
The H.I. function is used to prevent
elevation changes caused by
movement 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 elevation.
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.
