Owner's Manual

The RCR is a high-precision rotating laser and has
been factory calibrated within the tolerance
specified. Regularly check the calibration before
use, after transporting and after long storage
periods.
Be aware that a re-calibration performed by the
user is only as an approximation and the accuracy
of calibration depends on your care.
X/Y-axis Preparation
Note: For the purpose of calibration or
verifying level, the unit should be placed at a
distance of approx. 40-60 ft. from a vertical
target (e.g. wall).
1.Turn the levelling screws all the way down until
they stop.
2.Make a reference mark on each with a pencil.
Using the mark as an aid, turn the levelling screws
each up again by 3 turns.
3.Set the unit on a flat, somewhat level surface or
screw it onto a tripod.
4.Align the surface or the tripod in such a way that
the bubbles of the RCR are coarsely adjusted and
move freely.
Checking the calibration of the Y axis
1. Mark either levelling screw A or B as a reference
screw. Align the unit only with the other levelling
screws.
2. Level the unit with the other two levelling
screws. Turn on and shine beam on a vertical
target surface 50 to 65 feet away.
Note:
Any mode can be used but spot mode will be
brighter and more visible at longer distances.
3. When levelled, mark the point A on the target.
Calibration
Special features of Remote
Commander
By using the universal holding device the
RemoteCommander can be attached to a
levelling staff. LEDs on the back show the
same readings as the front so you can work
from behind the receiver.
Through the integrated magnet the Remote Commander can also be
used as an electronic target plate, e.g. in acoustic ceiling construction
and when setting up and adapting metal and storage shelves.
Using the Remote Commander as a Laser Receiver
Changing Batteries
RCR:
When the red LED is constantly flashing,
the batteries must be changed. To do
this, pull the lever under the unit slightly
downward and forward. Remove the
door and insert new batteries with
polarities shown on case indicating
which end of battery faces out. Replace
door. Requires four AA batteries.
RemoteCommander:
Turn the knob on the bottom side and
remove it. Change batteries inserting
with plus sign facing in and replace
knob. Requires two AA batteries.
Connection of an external AC adaptor to the rotation laser
When connecting an external AC adaptor, the batteries will be bypassed. It is not
possible to charge rechargeable batteries with the power supply attached to the
rotation unit. Please use only the AC adaptor supplied.
Note:
Batteries should not be exposed to excessive heat, such as sunshine or fire. å
