HOW TO USE THE LASER SYSTEM
POWERING THE LASER
Batteries
WARNING
Ni-MH batteries may contain small amounts of harmful substances. Be sure to charge the battery
before using it for the first time, and after not using it for an extended length of time. Charge only with
specified chargers according to device manufacturer‘s instructions. Do not open the battery, dispose
of in fire or short circuit; it may ignite, explode, leak or get hot causing personal injury. Dispose in
accordance with all applicable federal, state, and local regulations. Keep the battery away from
children. If swallowed, do not induce vomiting. Seek medical attention immediately
Recharging the Batteries
The laser is shipped with a rechargeable Ni-MH battery pack.
Note: The approximate charge of the batteries is shown at the left top side of the LCD.
The charger requires approx. 10 hours to charge empty rechargeable batteries.
For charging, connect the plug of the charger to the recharge jack of the battery pack.
New or long-time out-of-use rechargeable batteries reach their best performance after
being charged and recharged five times. For Indoor applications the charger can be
used as a power supply for the GL.
Alkaline batteries can be used as a backup. Insert 4 D-cell batteries noting the plus
(+) and minus (-) diagrams inside the battery housing.
The batteries should only be charged when the laser is between 50° F and 104° F (10°C to
40°C). Charging at a higher temperature may damage the batteries. Charging at a lower
temperature may increase the charge time and decrease the charge capacity, resulting in
loss of performance and shortened life expectancy.
RC602 Radio Remote Control
Powering the RC602
1. Open the battery door using a coin or similar pry device to release the
battery door tab on the RC602. RC602 will be shipped with alkaline
batteries Rechargeable batteries can be used optional but need to
be charged externally
2. Insert two AA batteries noting the plus (+) and minus (-) diagrams
inside the battery housing.
3. Close the battery door. Push down until it “clicks” into the locked
position.
Turning On/Off the Radio Remote Control
The radio remote control is a hand-held device that allows you to send operational commands to the laser
from a remote location.
Press the power button to turn on the radio remote control. A “ ” and additional vertical bars appear in the
right corner of the remote’s top display line indicating the radio connection status between the laser and the
remote control.
Note: When the remote control is initially turned on, the standard display (model number and software version)
appear for the first 3 seconds, then the axes symbols and last-entered grade for each axis briefly appear in
the LCD.
With every button press, the LCD backlight is activated and turns off automatically if no button is pressed for
8 seconds.
To turn off the radio remote control, press and release the power button.
Note: 5 minutes after the last button press, the remote control turns off automatically.

CALIBRATION
Checking Calibration of the Y- and X-Axes
1. Set up the laser 30 m (100 ft) from a wall and allow it to level.
2. Set the grade to 0.000% in both axes.
3. Raise/lower the receiver until you get an on-grade reading for the +Y axis. Using
the on-grade marking notch as a reference, make a mark on the wall.
Note: For increased precision, use the fine-sensitivity setting (1.5 mm/ 1/16 in.) on
the receiver.
4. Rotate the laser 180° (-Y axis toward the wall) and allow the laser to re-level.
5. Raise/lower the receiver until you get an on-grade reading for the –Y/axis. Using the
on-grade marking notch as a reference, make a mark on the wall.
6. Measure the difference between the two marks. If they differ more than 3 mm at 30
m (1/8 inch at 100 feet), the laser needs calibrating.
7. After checking the Y-axis, rotate the laser 90°. Repeat the above starting with the
+ X axis facing the wall.
Checking Calibration of the Z-(vertical) Axis
To check vertical calibration, you need a plumb bob with at least 10m (30ft) of string.
1. Suspend the plumb bob in front of a house i.e., attached to a window frame whose window height is at least
10m (30ft).
2. Set up the laser in vertical so that the laser beam strikes the receiver’s on-grade position at the top of the string.
3. Look for any deviation using the receiver from the top of the string to the bottom of it. If the deviation is more
than 1mm (<1/16 in.), the vertical axis needs calibrating.
Note: If calibration is required, please, refer to the calibration instructions on our Trimble website
