1312CAUTIONThe use of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.The GAT220 is a precision instrument, which must be handled withcare. Avoid shock and vibrations. Always store and transport thelaser and its accessories in the carrying case.Although your GAT220 is weather resistant, you must always keepyour laser and its accessories dry and clean after using. This willincrease the battery life.Do not store your laser at temperatures below -4°F (-20°C) orabove 176°F (80°C) because some electronic components couldbe damaged.Do not store your instrument in its case if the instrument or the caseis wet, to avoid water condensation inside the instrument.To maintain the precision of your GAT220, check it and adjust itregularly.Keep the aperture lens dry and clean. Use a soft cloth and glasscleaner to clean it.We recommend to regularly charge the batteries of the GAT220.Nevertheless, make sure to charge them only when they are out ofpower or becoming so. Recharging batteries that are still useablewill shorten their capacity.Detectors are recommended when it is difficult to see the laserbeam, such as outdoors or in bright light.If you cannot pick up the beam with the detector, check howyou are lined up with the laser. One of the head protection sup-ports on the laser may be blocking the beam; move to the leftor right to receive the beam.The head protection may be removed from the laser by pivotingthe two security locks. This will not affect the performance or thewater or dust resistance of the laser.5. Care and Handling6. Accessories5. Y LED will blink rapidly, indicating leveling. When the LED blinksslowly, the laser is ready to calibrate.6. If you have not moved the laser, use the Y marks made in previoussteps of “Checking Y axis”.7. Use arrows on the keypad to move beam up or down to thehalfway mark. If the Y axis is toward the wall with the marks,use the ^ key (8) to raise beam, and the v key (9) to lower beam.8. Press MAN key (5) to save the calibration you’ve just made on Yaxis. (On remote, use key with the small dot).If you are not sure of the calibration, don’t save it and turn the laseroff using the On/Off key.Final X to Y CheckAs a final check, compare X and Y axes to be sure that your adjustedcalibration is within the specs of ± 1/8”. The marks for X, X’, Y, andY’ should be no more than 1/4" apart at 100 ft. (6 mm at 30 m).4.3 Cone error checking1. Set up your GAT220 2 ft. or 1 meter from a wall (a) or apole and 100 ft. or 30 meters from another wall or pole (b).2. Turn the laser on.3. When the laser is leveled, stop the rotation and mark thelocation of the beam (center of the beam) on the near wall (a),using the detector if ambient conditions are too bright.4. Rotate the laser 180° and mark the location of the center ofthe beam on the far wall (b).5. Install the laser 2 ft. or 1 meter from the far wall. When theGAT220 has self-leveled, line up the beam on the previous mark (b).6. Mark the location of the beam on the wall near the first mark (a).7. Compare the two measurements. If the difference between aa’-bb’ is more than 1/4" or 6 mm, contact your local service center.
