Troubleshooting; Influences On Accuracy - Milwaukee 3712 Operator's Manual

Direct Read Out and Arrow Indicator
If a laser is sensed, the Direct Read Out, arrow indi-
cator and Laser Locator Indicator LED will illuminate
to guide the user in moving the receiver to align the
laser with the center. If no laser is detected, the LED,
arrow indicator will remain off, and the Direct Read
Out will show no value and will display "- - -".
• Laser Locater Indicator LED is blue: - Move the
receiver location up until on center.
• Laser Locater Indicator LED is green: - The line
being detected from the laser is on center.
• Laser Locater Indicator LED is red: - Move the
receiver location down until on center.
NOTE: If the laser leaves the sensor, the up or down
arrow segments will begin to cycle indicating the
direction that the laser was last detected.

Troubleshooting

• Ensure batteries are inserted correctly according to
the +/- polarity marked in the compartment.
• Replace batteries that may be at the end of life.
• Ensure the tool's internal temperature is within speci-
fied operating ranges. If stored in excessive heat or
cold, allow at least 2 hours to acclimate to ambient
temperature before turning on the tool.
• If the receiver freezes, press and hold the power
button for 15 seconds or remove the batteries to
reset.
• Leveling Error - The laser was unable
to find a leveling solution due to time
out or out of leveling range. Adjust laser
to be on a level surface, any pressing
of the buttons on the rotary laser may
trigger the bump alarm or reveling may
occur. If that doesn't work, press the leveling mode
button on the laser. If that doesn't work, try power
cycling the laser.
• Temperature Alarm - Indicates that
the laser is too hot or cold. To resume
work, the laser must be returned to a
suitable operating temperature. Note
the internal temperature may be sev-
eral degrees warmer than ambient
temperature.
• Wrong Vertical Orientation Alarm -
This will appear if the laser is placed
in a non-compatible vertical orienta-
tion. Adjust laser as directed on the
LCD screen. The Keypad should be
facing up and parallel to the ground.
Pairing Failure:
• Ensure the remote/receiver is powered on, within
the distance range and in Pairing Mode.
• Avoid artificial overhead lighting on the remote/
receiver sensor.
• Avoid the laser projecting a beam onto the remote/
receiver sensor during pairing.
• Avoid transmitting devices.
• Place the laser on a stable surface during pairing
to prevent interruption from bump alarms. For best
results, pair in the horizontal orientation.
• The no connection error may appear if
your devices are not paired. Try repeat-
ing the pairing steps in the "Pairing the
Remote/Receiver with the Rotary La-
ser" section.
If problem persists, please contact an
authorized MILWAUKEE service center
for support.
ACCURACY FIELD CHECK
Perform the Accuracy Field Check
NOTICE
procedure immediately upon unboxing
of each remote/receiver and before exposure to
jobsite conditions. See "Accuracy Field Check"
for information. Should any deviation from listed
product accuracy be found, please contact an autho-
rized MILWAUKEE service center. Failure to do so
could result in rejection of warranty claim.

Influences on Accuracy

Sunlight or other extreme lighting conditions can
adversely impact accuracy. For best results, use
indoors or avoid direct sunlight.
Abusive treatment of the laser level Remote/Re-
ceiver, such as excessive impacts from drop, can
lead to deviations in product accuracy.
Therefore, it is recommended to conduct the Field
Check procedure after any impact or before complet-
ing any critical jobs.
For best results, use with MILWAUKEE Lasers.
Remote/Receiver Accuracy
Check Procedure
1. Set up compatible laser 30' from flat wall.
2. Ensure the laser source is self leveled and per-
pendicular to wall.
3. Place Remote/Receiver flat on wall directly in
front of the laser source and slightly below the
projected laser line.
4. Keeping the Remote/Receiver bottom parallel
with the ground, raise receiver until down arrow
appears.
5. Lower the Remote/Receiver until center line ap-
pears.
6. Mark a line on the wall – Point I.
7. Continue to lower Remote/Receiver until the up
arrow appears.
8. Raise Remote/Receiver until center line appears.
9. Mark a line on the wall – Point II.
10. Measure the distance between Point I and Point
II – divide by 2. After complete, compare this to the
Receiver Accuracy table in the "Setting Accuracy"
section.
NOTE: If the measured accuracy is out-of-spec
according to this table, contact an authorized
MILWAUKEE service center.
