3. Safety Instructions
Please read and understand all of the following instructions, prior
to using this tool. Failure to do so, may result in bodily injury.
ATTENTION IMPORTANT
• Read all instructions prior to operating this laser tool. Do not remove any labels from tool.
• Do not stare directly at the laser beam.
• Do not project the laser beam directly into the eyes of others.
• Do not set up laser tool at eye level or operate the tool near a reflective surface as
the laser beam could be projected into your eyes or into the eyes of others.
• Do not place the laser tool in a manner that may cause someone to unintentionally
look into the laser beam. Serious eye injury may result.
• Do not operate the tool in explosive environments, i.e. in the presence of gases or
flammable liquids.
• Keep the laser tool out of the reach of children and other untrained persons.
• Do not attempt to view the laser beam through optical tools such as telescopes as
serious eye injury may result.
• Always turn the laser tool off when not in use or left unattended for a period of time.
• Remove the batteries when storing the tool for an extended time (more than 3 months)
to avoid damage to the tool should the batteries deteriorate.
• Do not attempt to repair or disassemble the laser tool. If unqualified persons attempt
to repair this tool, warranty will be void.

Mode
The instrument has six operating keys with their functions below:
Power Key
Power on and off the instrument by pressing this key. The
instrument will beep twice when turning it on and off.
Laser Key
Pressing this key will turn on the laser beam and the laser
icon will appear on the LCD. The instrument will also beep
once. Pressing this key again will turn off the laser beam
and the laser icon will disappear on the LCD. Note: The instrument
must be turned on for the laser beam to work.

CAL Key
The calibration key is used for re-calibrating the instrument
in both the horizontal and vertical direction. Refer to
Section 8 “Calibration” for details.
Mode Key
Push the MODE key to switch from one dimension to
another. This controls which dimension your electronic
module will measure in. Your level has the capability to measure in
Degrees, Percentage of slope, Millimeters per Meter, Inches per Foot
(Slope, Pitch) in decimal form and Inches per Foot in fractions of an
inch. A symbol on the upper right of the screen will explain which
MODE you are currently in.
Sound Key
Pressing this key will turn on the sound function and the
sound icon will appear on the LCD. Pressing the key again
will turn off the sound function and the sound icon will disappear on
the LCD. The instrument will beep once when turning the sound on
and off. The beep will sound at 0º and 90º.
Hold Key
The angle readings change in accordance with the change of
the incline. Press the key (unit will beep once) to enter into
the “hold” mode. The measured angle reading will be held. The
display will flash and the angle measurement will not change.
Pressing the key again (unit will beep once) will stop the “hold” mode
and measured value will change with the incline.

Automatic Shut-off
This instrument will shut-off automatically if no operation is received
within 20 minutes.
Low-power Indication
The battery symbol will flash on the LCD when the battery power is
low. Replace the batteries as soon as possible.

Locking Arm
When the surface is long, turn the angle level arm to 180º, then tighten
the locking screw clockwise. You can lock the arm at any angle within
the range of 0º to 180º.
The laser point will be parallel with the reference plane
Measuring the inclining angle to
the level plane.

8. Self-Check and Calibration
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
To guarantee the best measuring precision of the incline, vertical and
leveling plane:
Calibrate before first use.
Before important measurements.
After a hit or drop.
Horizontal Calibration
Put the angle level on a smooth level plane and observe the LCD
display. Note the reading after ten seconds. Then turn the angle
level 180º on the same plane. After another ten seconds note the
second angle reading. Calibration is necessary if the difference
between the two measuring readings is over 0.1º.
©2009 Johnson Level & Tool - Rev. 1 11
Vertical Calibration
Put the angle level on a smooth
vertical plane and observe the LCD
display. Note the reading after 10
seconds. Then turn the angle level
180º on the same plane. After
another ten seconds note the second
angle reading. The calibration is
necessary if the difference between
the two measuring readings is
over 0.1%.
Calibration in the Horizontal Direction
1. Put the level on a flat surface and press the “CAL” button. -0- will
be displayed. Wait 10 seconds.
2. Press the “CAL” button again and -1- will be displayed. Turn the
level 180 degrees on the same surface. Wait another 10 seconds.
3. Press the “CAL” button once again. If it beeps once the calibration
is completed, it is correct. If it beeps twice the calibration is not
completed and the procedure should be repeated. If it continues
to beep twice the sensor may have been damaged and the unit
should be serviced.
4. Then do the same thing for the vertical with both the logo on the
top and with the logo on the bottom.
