Turning On/Off Line Alert (HR500 only)
Line alert is used primarily when the laser is in vertical mode to control the "on-grade"
alignment of the laser beam.
The receiver always starts up in the last selected line alert mode. If the receiver starts up
with the line alert on, all LEDs flash simultaneously and the receiver beeps for 3 seconds.
1. Press and hold the grade-sensitivity
button for 5 seconds to enter the
line-alert mode.
Note: The receiver cycles through the
line alert settings, which include on
and off, every 3 seconds.
Note: When line alert is on, all LEDs
flash simultaneously and the receiver
beeps for 3 seconds. When line alert is

off, both red LEDs flash for 3 seconds.
Note: On-grade monitoring starts after 5 seconds of a continuous on-grade
condition. To confirm that the laser beam is still aligned to on-grade, all LEDs
flash once per second every 10 seconds. If the laser beam is disturbed or moved from
on-grade, after 5 seconds the LEDs start flashing. After 45 seconds of the beam being
disturbed continuously, the receiver starts beeping once per second, regardless of the
audio setting.
