Checking vertical accuracy
To check the vertical accuracy of your laser, place the
unit in the laydown position on a flat, level surface
approximately 15-30 meters (50-100 ft.) from a wall. See
illustration {N} in the back, inside cover of this manual.
X Hang a plumb line on the wall.
X Move the laser until the vertical, rotating beam is
aligned to the plumb line.
X If the rotating beam is not plumb, adjustment is neces-
sary.
Adjusting level accuracy – The X-axis
After checking the accuracy of your laser, perform the
following steps to adjust the accuracy of the X-axis.
X Turn off the laser.
X Press and hold the Auto/Manual key {B-1}, then press
the On/Off key {B-3}.
X After the X and Y LED’s blink three times simultane-
ously, release the Auto/Manual key.
• The X-axis LED will flash rapidly (red) while
leveling.
• The X-axis LED will flash slowly (red) when ready
for adjustment.
• The head will not be rotating.
• To use a receiver, press the Scan/Rotation key
{B-2} to start rotation mode.
X Press a CCW/CW key {B-6 or B-7, hidden on
Roteo 20HV} to adjust the beam up or down. Five
presses of the key will move the beam approximately
1.5 mm at 30 meters (1/16" at 100 feet). Use of the
remote for this adjustment will make the job easier by
not disturbing the laser.
After completing the changes to the X-axis, do one
of the following steps:
X Press the Plus key {B-9} after completing adjustment
to switch to the Y-axis.
X Press the Minus key {B-8} to exit adjustment mode,
save changes and turn off the laser.
X Press the On/Off key {B-3} at any time to turn off the
laser without saving any changes.
Adjusting level accuracy – The Y-axis
After checking the accuracy of your laser, perform
the following steps to adjust the accuracy of the Y-
axis.
X If already in adjustment mode for the X-axis, press the
Plus key {B-9} to switch to the adjustment of the Y-
axis.
X If not in adjustment mode, follow the steps above for
entering adjustment mode, then press the Plus key to
switch to the adjustment of the Y-axis.
• The Y-axis LED will flash rapidly (red) while
leveling.
• The Y-axis LED will flash slowly (red) when ready
for adjustment.
• The head will not be rotating.
• To use a receiver, press the Scan/Rotation key
{B-2} to start rotation mode.
X Press a CCW/CW key {B-6 or B-7, hidden on
Roteo 20HV} to adjust the beam up or down. Five
