LASER OPERATION
• To extend battery life per charge, turn the laser off when it is not
in use.
• To ensure the accuracy of your work, check the laser
calibration often. Refer to Field Calibration Check under
Laser Maintenance.
• Before attempting to use the laser, make sure the device does
not show any defects and is in proper working order.
• Extreme temperature changes can cause movement or shifting
of building structures, metal tripods, equipment, etc., which can
effect accuracy. Check your accuracy often while working.
• If the device is dropped or has suffers a sharp blow, have the unit
checked by a qualified service center before using the laser.
