Using Channel Link
Channel Link can be used to eliminate interruptions
from other lasers on a busy jobsite, by distinguish-
ing and detecting the preferred laser. The Remote/
Receiver cannot distinguish between two lasers at
the same time. Be sure that only one laser is striking
the Remote/Receiver sensor at a time.
1. Select the Channel Link icon from the main menu,
and press the OK button. Selecting a channel will
update the Remote/Receiver setting as well as
update the setting on any paired laser.
2. Use the up/down arrows to select the desired
channel, then Press the OK button to confirm.
NOTE: A Remote/Receiver in "CH --" will detect
lasers in any channel. While the Remote/Receiver
is in CH 1,2,3 it will only detect lasers in matching
Channels. Select a unique channel to distinguish
the laser from others on the jobsite or select "CH--"
to detect any green rotary MILWAUKEE rotary
laser on the same jobsite.
3. To detect all lasers, return to the channel menu
and select "CH--".
NOTE: Channel Link is only compatible with certain
RPM's and functions. Some settings may automati-
cally change when this function is used. Press the
OK button to clear any setting change notification of
the Remote/Receiver.

Laser Calibration

User calibration of the laser can be conducted with
the use of a paired Remote/Receiver. At any time
during calibration, press the menu button to abort
the calibration, and exit without saving the settings.
Recalibrating the Horizontal (X/Y) axis:
1. Select the calibration icon from the main menu,
and press the OK button.
2. Place the laser on a stable surface (such as a
MILWAUKEE Rotary Laser Tripod) in the hori-
zontal position. After pressing the OK button, the
calibration record, including the laser field calibra-
tion, laser service calibration, and next suggested
calibration is displayed. MILWAUKEE suggests
that the tool should be professionally calibrated
once per year or after any serious drop event.
Between professional servicing, field calibration
can be completed for minor adjustments in per-
formance. Press the OK button to begin the field
calibration procedure.
3. Enter the current date of the recalibration using
the up and down arrows and press the OK button
to begin calibration.
4. Select "X/Y" axis for recalibration and press the
OK button.
5. Select the desired calibration accuracy. Note that
longer distances are required for more precise
calibration. Press the OK button to continue. The
screen will change to show "-X" as the first axis
of calibration. Press OK to continue. Separate the
laser and Remote/Receiver in the "-X" axis by the
distance indicated. Then press OK to continue.
6. Ensure the Laser is projecting on the sensor. Once
the OK button becomes active, press the OK but-
ton to continue. Ensure the Remote/Receiver is
secure on a stable and level surface.
7. Return to the laser. Using the iron sights, adjust
the laser so that it's aimed perfectly at the Re-
mote/Receiver sensor in the X- axis. Allow the
Remote/Receiver time to take a reading. Once
complete, the Remote/Receiver and laser will
beep to indicate completion and prompt to move
to the next axis.
8. Rotate the laser clockwise 90°, and use the iron
sights to align the Y+ axis with the sensor. Wait
for the audible beep sound.
9. Repeat for the X+, then the Y-. After the Y- is
completed, the "COMPLETE" screen will appear
on the Remote/Receiver. Press OK, the settings
will be saved and the laser will power off.
Recalibrating the Vertical (Z) axis:
1. Place the laser on a stable surface elevated off
the ground in the vertical orientation. After the
calibration log is displayed, press the OK button
to start calibration.
2. Enter the current date of the recalibration using
the up and down arrows and press the OK button.
3. Select "Z" axis for recalibration and press the OK
button. The see manual icon will appear. For the
best results, read below steps carefully before
pressing the OK button to continue.
4. Hang a Plumb Bob line at least 30' in length from
the ceiling. Press the OK button to continue. En-
sure that the laser is aligned with the reference line
and is at least 6' from the Plumb Bob line. Press
the OK button to continue.
5. Allow a few seconds for the laser to enter calibra-
tion mode. When ready, the laser will begin to
rotate and the left/right and OK buttons on the
LCD screen will become selectable. Use the arrow
buttons to slowly adjust the laser plane so that it's
parallel with the reference Plumb Bob line. Once
aligned, press and hold the OK button to complete
calibration.
6. When calibration is complete, the screen will say
"COMPLETE", press the OK button. The settings
will be saved and the laser will be powered off.
NOTE: If calibration fails, the screen on the Remote/
Receiver will prompt users to restart the calibration
process. If calibration fails multiple times, contact an
authorized MILWAUKEE service center. User is able
to press the main menu button to abort the procedure.
Changing the Bump Sensitivity
The laser is defaulted to high sensitivity bump setting
from the factory. This setting can be changed using
a paired Remote/Receiver.
• Select the bump setting icon from the main menu.
• Use the up/down arrows to select the desired set-
ting then press OK to apply the setting. The laser
will re-initialize the bump alarm in it's new setting.
