H.I. Alert
H.I. (height of instrument) Alert stops the laser automatically if the laser is
disturbed or moved, preventing inaccurate readings.
It will function only when selected. To activate this safeguard feature, press
the H.I. key (1). The LED indicator (9) will blink rapidly while the laser is
self-leveling.
About 30 seconds after the head starts to rotate, the LED will blink slowly,
i
ndicating the H.I. alert is activated.
If the laser is disturbed while in H.I. Alert mode, the head will stop rotating, the
beam will turn off, and the LED will stay on.
To
start the laser rotating again, press On/Off twice.
Check if the beam elevation has changed from its original benchmark
position.
The laser is no longer in H.I. Alert mode. Press key (1) to return to H.I.
Alert.
Rotation
Rotation Speed
The head rotates at 6 speeds: 0, 90, 150, 300, 450, and 600 rpm. 300 rpm is
the default setting.
Using the keypad or remote, you can stop the rotation with the - key and
move the beam point with the + or - keys.
T
o start the rotation again just press the + key for a few seconds.
Press the + to increase the rotation or - to decrease the rotation speed.
T
he laser beam is more visible at slower rotation speeds. The faster speed
(600 rpm) is required for many machine control receiver applications.
It is important to check while you're using the laser that it has not
been moved and that your setting is still accurate.
