6. Operating Instructions
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Battery Installation
Note: Always check to be sure that the on/off switch is in the off
position before removing and replacing batteries.
NiMH Rechargeable Battery Pack Installation
1. Unscrew the battery cover bolt and remove
the battery cover.
2. Put 2 rechargeable battery packs into the
battery case and then insert the plug of the
battery pack lead-wire into the socket at the battery case.
3. Screw the battery cover bolt back on.
NiMH Rechargeable Battery Charging
Using the battery charger (included), charge the rechargeable battery
pack through the outlet jack. When the charge indicator lamp turns
from red to green (after approximately five hours), the NiMH
rechargeable battery pack has been fully charged.
Note:
(1) For the first two charges of new rechargeable batteries, it is
necessary to charge for 12 plus hours.
(2) The unit can still work during charging with the charger.
(3) Do not charge alkaline batteries to avoid explosion.
(4) Used (discharged) batteries are hazardous waste and should be
disposed of properly.

Before Using the Laser
When you charge the new battery or one which has not been used for
long periods of time, it may not reach full charge until after you have
discharged it fully in use and recharge it several times.
Instrument Usage
1. Put in NiMH rechargeable battery pack, or 4 “C” alkaline batteries (not
included), or connect to DC power through the outlet jack.
2. Place the instrument on a tripod, connect it to the tripod using the
5/8” screw thread at the bottom of the instrument.
Note: If the instrument is inclined beyond the self-leveling range, the
instrument will deliver an audible alarm. You will need to
re-position the instrument.
3. Press power switch to turn power on. Press buttons on remote control to
adjust for slope feature.
4. After finishing operation or before moving the instrument, turn the
power off.
Alkaline Battery Installation

power indicator lamp will light up and then the
instrument will automatically level itself, with
rotation occurring once the unit is level.
2. Press the power button again to power off.
Low Battery Indication
If the battery indicator lamp is lit, this means low
battery voltage. To ensure normal operation, replace
batteries or charge the rechargeable NiMH battery pack.
Alarm If Beyond Range
If the instrument is inclined beyond the self-leveling
range of ±5° , it will deliver an audible alarm, and
the power indicator lamp will blink. You will need
to re-position the instrument until it is within the
leveling range.

Height of Instrument (Tilt Mode)
1. After powering on the instrument and entering into
auto-level status, press the tilt button. When the
indicator is on (see figure), the instrument enters
into TILT mode. If the leveled instrument is moved
or bumped, the head will stop rotation and the TILT indicator light and
laser beam will flash instead of the unit performing the auto-level
function. Press the tilt button on the panel or remote to quit the tilt
mode and enter into auto-level status.
2. Press the tilt button on the laser or remote again to enter the tilt mode.
Slope Adjusting Function (SLOPE)
This function must be operated by the remote control (see operating
panel shown in fig.1).
1. Select slope adjusting direction
The first press of X/Y button will illuminate the X indicator light (fig. 2).
The second press of X/Y button will illuminate the Y indicator light (fig.
3). The third press of the X/Y button will quit the slope-adjusting func-
tion and enter the unit into auto-level status.
2. Adjust the slope angle
When in either the x-axis or y-
axis, press either of the two
up/down arrow keys on remote
control (fig.1) to adjust slope
angle.
Note: A single press of either key
activates fine tuning while a
continuous pressing activates
quick adjustment.

Adjust the inclination extent of the slope
Pressing the up/down arrow keys on the remote control, will adjust the
inclination of the instrument slope. A single press will cause a
slight adjustment and a continuous press will cause a quick adjust-
ment.
If laser is taken past its slope range (±8º), the laser will deliver an
audible alarm and the laser beam will flash and stop rotating.
Sleep Mode
1. The first press of the
POWER button on the
remote control (fig.4) will
make the instrument enter
sleep mode. The power indicator lamp on the panel is lit (fig.5),
the laser beam goes out, and the instrument head stops rotation.
2. The second press of the POWER button on the remote control will
make the instrument quit sleep mode and enter auto-level status.
Timed Power-off Function
Power instrument on and press the power key on the remote control,
the instrument will enter the sleep mode. Under the sleep mode, if
there is no operation for 30 minutes, the instrument will power off
automatically. Under sleep mode, press the power key on the
remote control to make the instrument start.
