1. Battery Installation
Open the battery door, and put in one 9V battery according to the
polarity shown inside. Then snap the battery door
back.
Note:
• Remove the battery when the unit is being
stored for a long time.
• Replace the battery when the low voltage
indicator shows a low battery.
2. perating Instructions
IMP RTANT: This detector will only work when the laser is in
the pulse mode.
A. Press the Power on/off key: The detector
will beep twice and all the symbols will be
displayed on the display window. After
0.5 seconds the detector will enter its
detecting mode.
B. Detecting the horizontal laser signal: Put
the detector in a vertical position and center
the bubble in the horizontal vial with the
reception window facing the laser. A down
arrow shown on the display window and a lit
red light indicates the laser signal is below the detectors on grade

mark. An up arrow plus a yellow lit light indicates the laser signal is
above the detectors on grade mark. A middle sign plus a lit green light
indicates the laser signal is on grade.
Note: When the laser signal moves towards the
center position, the displayed up or down
arrows will decrease in size, until the center
single line appears.
C. Detecting the vertical laser signal: Put the
detector in a horizontal position (center the bubble
in the horizontal vial) with the reception window
and indicator lights facing up. ave the reception
window face the unit to receive the vertical laser
signal. Left arrow shown on LCD plus a lit red light
indicates the laser signal is on the left side of center.
A middle sign with a lit green light indicates the
laser signal is on the middle position. A right arrow plus a lit
yellow light indicates the laser signal is on the right side of center.
D. Press the Power on/off key to power off the detector. The
detector will beep twice for off.
3. Sound Function
Pressing the sound key when the unit
is powered-on. This will switch the
unit between sound on and sound off,
note the sound sign indication on LCD.

Sound function on:
• If the laser signal is on the top (left) side, then the detector will
give a fast tone.
• If the laser signal is on the bottom (right) side, then the detector
will give a double tone.
• If the laser signal is on the middle, then the detector will have a
solid tone.
4. Automatic Shut-Off Function
When not receiving a laser signal and with no operation of the keys
for six continuous minutes, the unit will power off automatically to
preserve battery life.
5. Low Battery Indicator Function
• When the power indicator sign is blinking, it
indicates that the battery is low and should
be replaced.
• A very low battery will result in an automatic
power-off, which requires the user to
replace before continued operation.

8. Self-Check & Fine Calibration
IMP RTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Horizontal line accuracy (horizontal)
1. Place unit on a tripod approximately 5m from a wall. Secure the
instrument on the tripod.
2. Face the front of the instrument to the wall, unlock the
instrument, and power on the horizontal and vertical laser lines.
Make a mark on the wall where the cross-line is displayed. Label
this as ‘A’.
3. Make a mark 2.5m from A, along the horizontal laser line, and
label as ‘M’.
4. Turn the instrument until the vertical line meets ‘M’, and then
make a mark 2.5m from ‘M’, and 5m from ‘A’. Label this mark as
‘B’. Also make a mark on the vertical line where it meets ‘B’.
5. Measure the height distance between ‘M’ and where the
horizontal laser line currently sits.
6. If e>1mm, the instrument accuracy is out of tolerance, and cali-
bration is necessary.
Horizontal accuracy self-check (Vertical)
1. Stand up two straight poles/boards 5m from each other, or two
walls which are parallel and more than 5m distance.
2. Place the instrument on the tripod, and place in the center of
the poles/boards/walls, and level the instrument by adjusting
the tripod.
6339H_Manuals 10/24/12 12:56 PM Page 19

20 ©2012 Johnson Level & Tool
3. Power on horizontal and vertical laser lines, and make a mark
where the cross laser meets target ‘A’. Mark this as ‘A1’.
4. Turn the instrument by 180°, so that the cross line meets target
‘B’. Mark this as ‘B1’.
5. Move the tripod within .6m of target ‘A’. Make a mark where the
cross meets target ‘A’, and label as ‘A2’.
6. Rotate the instrument by 180° and make a mark where the cross
meets target ‘B’, and label as ‘B2’.
7. Calculate (A1-A2)-(B1-B2) = E. If the absolute value of E is above
1mm, the instrument accuracy is out of tolerance and calibration
is required.
Self-check and Calibration
The instrument has two calibration apertures. Aperture ‘A’ adjusts
the horizontal axis. Aperture ‘B’ adjusts the Vertical axis
Notes regarding adjustment:
1. Use a 3mm exagon tool for adjustment.
2. The adjustment of each axis may influence the other. When
making fine adjustments in the left/right direction horizontally, the
front and back direction vertically may change. When adjusting
the front/back direction vertically, the left and right direction will
possibly change. Adjustments may need to be checked and
repeated alternately.
3. The adjustment of the self calibration screw cannot exceed 4
turns in either direction.
4. If the instrument accuracy cannot be adjusted through self
calibration, please contact an authorized repair facility, or contact
Johnson Level & Tool.
