2. Basic Operation

2.1 Standard Set-up Levelling
(see dia over page)
Place unit on tripod and roughly set up so that the instrument is within
5% of level.
Switch the unit on (d).
The unit will then level itself and the diode will emit a beam and
commence spinning. The instrument will commence spinning at its
maximum speed of 600rpm.
If the unit is bumped or moved the laser will stop and the out of level
warning symbol will flash. After the instrument has re-levelled itself the
laser will recommence spinning.
- Warning – If the unit has been bumped or moved and the unit
recommences spinning, the instrument may not automatically be at the
original level. Re-check on a datum point.
2.2 Hi-Alert Mode:
Using the Hi alert mode, button (i), if the laser is
bumped or moved it will not re-level & recommence spinning until you
press button (i) again, therefore you can be assured accuracy

visibility; press the speed control button (h).

Using the bracket included, mount this onto a
staff or grade rod.
Turn the receiver on and raise or lower the receiver on staff until it makes
