2.1 Horizontal set-up and operation
1.
The GAT220 laser can be used directly on the ground or on a
standard 5/8-11 tripod.
2.
Press the On/Off key (1) to turn the laser on. The laser does a
self-test when turned on. The beam blinks while the laser is self-level-
ing. After it has leveled, the head will start to rotate.

To select the H.I. Alert, press the H.I. key (3). The H.I. Alert func-
tion will be active 30 seconds after the GAT220 has finished its
self-leveling.
4.
There are two rotation speeds: 90 rpm and 600 rpm (the default
speed). To change to 90 rpm, press key (7). Press again to stop the
rotation.

To turn the laser off, press On/Off .
2.2 H.I. Alert
The H.I. Alert feature stops the laser automatically and sounds an
alarm if the laser is disturbed, preventing inaccurate readings.
It functions only when selected.
To activate this safeguard feature, press the H.I. key (3) after
turning the laser on. The LED (4) will blink rapidly while the laser
is self-leveling.
