When the keypad is turned on, an “H” for horizontal mode or a “V” for vertical mode will appear on the display (26). The A710 has a wide self-leveling range; however, if the laser is set up out of the leveling range, a triangle with an exclamation point will appear on the display (25).
Choice of transmission There is two-way communication between the laser and the remote control. If the remote is within range and properly ψ or ↑ ) will appear communicating with the laser, a symbol ( on the display (28). ψ) The remote signal can be either radio frequency (RF/ infrared (IR/↑...

H.I. Alert H.I. (height of instrument) Alert stops the laser automatically if the laser is disturbed or moved, preventing inaccurate readings. It will function only when selected. To activate this safeguard feature, press the “lock” key (11). A lock is also shown on the display (22).
Scanning Scanning mode allows you to see the beam easier at a distance. To switch from rotation to scan, press the scanning key (17). A scanning symbol appears on the display (21). The scanning beam has three lengths, shown as 1, 2, or 3 on the display.
Calculating Percent of Grade Percent of grade is the change in elevation from Point A to Point B over a 100 ft. distance. To calculate %, divide the difference in elevation between A and B by the distance and multiply by 100. Example 1 –...
Checking the Grade It is recommended that you check if the grade you selected is correct and that the laser is positioned correctly in relation to the grade. Use a detector to pick up the beam. A +1% grade will have a 1 ft.
For optimum life of the battery, it is recommended to charge the battery after fully discharged. To assure battery life, do not charge over 20 hours. Although the A710 is waterproof, do not charge it while it is in water or submerged. Remote Control Battery If the remote control batteries are weak, the display will blink.
Checking and Adjusting the A710 THIS CHAPTER IS VERY IMPORTANT: Here are a few simple instructions to check your A710 for calibration. Remember that the laser is a precision instrument and that it is important that you keep it calibrated and in proper condition.
Checking X Axis 1) Place the laser on a flat surface or tripod 50 or 100 ft. (30 m) away from a wall. Position so that -X is facing the wall (this is the side of the laser with the On/Off key). 2) Turn on the laser and remote control.
4) If you have not moved the laser, use the X marks made in Steps 3 & 5 of “Checking X axis.” Mark the spot that’s halfway between the two marks. 5) Use the left and right arrows on the multi key (10) to move the beam to the halfway mark.
symbol H over a point appears on the display (27) to indicate that you are calibrating a horizontal axis. 2) Press the rotation key (18) and choose a rotation speed with the multi key (10). Note that the H symbol (27) has stopped blinking.
4) Use either scan or rotation mode. Using the scanning beam is easier, but if you cannot see the beam, work in rotation mode with a detector. To change from rotation to scan mode: press scan key (17) and choose the widest scan length – 3 – with the up arrow of the multi key (10).
CAUTION: Do NOT use the left or right arrows. 5) After completing the Z calibration, simultaneously press the backlight key (12) and X / Y key (15) to exit calibration mode. This will also turn the laser off. Cone error checking 1) Set up the laser about 2 feet away from a wall (a) or pole and 100 feet from another wall (b) or pole.
1) The A710 is a precision instrument that must be handled with care. Avoid shock and vibrations. 2) After use, it’s recommend that you wipe the laser dry and store in a dry place.
