▶ For these batteries, use only the Hilti PRA 85 AC adapter.
3.3 Automatic alignment
The tripod can be automatically aligned with the Hilti rotating lasers PR 30­HVS, PR 35, PR 300­HV2S or PRI
36. We recommend using the Hilti rotating laser PR 30­HVS. This was specially matched to the PRA 90 and
has a three-device communication system between tripod, rotating laser and the associated remote control
unit PRA 30.
Using these three components together, a laser plane can be aligned onto a precise point automatically.
Only the target height has to be indicated using the PRA 30, and the PRA 90 directs the laser plane of the
PR 30­HVS rotating laser exactly to that height.
If other rotating lasers are used, you will need the PRA 92 remote control unit in order to move the tripod up
and down. Automatic alignment is therefore not possible.
