2. How to use your A110 laser
2.1 Setup
• Horizontal
The laser can be mounted on a 5/8-11 tripod (7) or placed direct-
6
ly on a solid, stable surface. It can also be suspended from a
ceiling grid using the wall mount.
• Vertical
The laser can be mounted on a 5/8-11
tripod (8) or placed directly on its back
(opposite the handle) on a solid, stable
surface.
Remove the wall mount, if attached.
The A110 has a wide self-leveling
range; however, if the laser is set up out
of the leveling range, the laser beam will
continue to blink and rotation will not
start.
• Turning on the laser
Turn on the laser with the On /Off key (14). It does a self-test
and the beam blinks while the laser is self-leveling. After it's
leveled, the head rotates. You can choose H.I. Alert mode or
change to manual mode.
2.2 Automatic / Manual modes
The A110 is in automatic self-leveling mode when turned on.
Once the instrument has self-leveled, the laser head will start
rotating.
In manual mode (16), the laser does not self-level: this means
that the beam will rotate even if the laser is not leveled. It can
therefore be used when manual grade setting is required. See
later section on setting slope in manual mode.
CAUTION: In manual mode, the beam rotates even if
the laser is not leveled.
2.3 H.I. Alert mode
The H.I. feature stops the laser automatically and sounds an
alarm if the laser is disturbed, preventing inaccurate readings. It
functions only when selected.
