2. Turn on the laser.
3. Use either scan or rotation mode. Using the scanning beam
is easier, but if you cannot see the beam, work in rotation mode
with a detector.
4. Move the scan to the wall over the plumb line, sliding the laser
left or right to line up the beam over the plumb line. If in rotation
mode, use the < or > keys (10 or 11) to move the beam.
5. Move the scan up and down the entire length of the plumb
line. If the beam is slanted, and not vertical like the plumb line,
the Z axis needs to be calibrated.
4.8 Calibrating Z axis
The laser must be calibrated to bring the rotating Z beam paral-
lel to the plumb line.
1. Turn off the laser (14).
2. While keeping (16) pressed, turn on the laser (14).
3. After the 3 LEDs blink in sequence, release Man key.
4. The Z LED (19) will blink rapidly for a bit and then slowly,
indicating it's ready to be calibrated in Z axis. The beam will
not be rotating.
When it's in calibration mode, rotate the beam by pressing the
scan key, and make these adjustments:
1. Use the < and > keys (10 and 11) until the beam is perfectly
vertical and parallel to the plumb line.
2. Move the beam slightly so that the beam is over the plumb
line for the final check.
3. After completing the Z calibration, press the key (12) to save
it. The laser will shut off. If you are not sure of the calibration
and do not wish to save it, turn the laser off with the On/Off
key.
4.9 Cone error checking
1. Set up the laser about 2 feet (60 cm) away from a wall (A)
or a pole and 100 feet (30 m) from another wall or pole (B).
2. Turn the laser on.
3. After it has self-leveled, stop the rotation and mark the loca-
tion of the beam (center of the beam) on the near wall (A). Use
a detector if ambient conditions are too bright.
4. Rotate the laser 180°. Mark the location of the center of the
beam on the far wall (B).

5. Set up the laser about 2 feet (60 cm) away from the far
wall. After the laser has self leveled, line up the beam on the
previous mark (B).
6. Mark the location of the beam (A') on the other wall near the
first mark (A) in using if necessary the detector.
7. Compare the two sets of marks on the wall. If the difference
between AA'-BB' exceeds 1/4"(6 mm), contact your local serv-
ice center.
5. Care and Handling
CAUTION
Using of controls or adjustments of procedures other than those
specified herein may result in hazardous radiation exposure.
The A110 is a precision instrument which must be handled with
care. Avoid shock and vibrations. Always store and transport
the laser and its accessories in the carrying case.
Although weather resistant, you must always keep your laser
and its accessories dry and clean after using. This will increase
the battery life.
Do not store your laser at temperatures below -4°F (-20°C) or
above 176°F (80°C) because some electronic components
could be damaged.
Do not store your instrument in its case if the instrument or the
case are wet, to avoid water condensation inside the instru-
ment. To maintain the precision of your A110, check and adjust
it regularly.
Keep the lenses of the apertures dry and clean. Use a soft cloth
and glass cleaner to clean them.
