1. Self leveling will start at once The unit is leveled when the leveling indicator 3 is no longer flashing once every second The rotor will not spin until the unit is leveled For the first five minutes after the laser self levels the LED lights solid then flashes every four seconds to let you know the laser is still level In order to switch the unit off press the power button 1 again If the laser is positioned beyond its self leveling range of 8 the manual and leveling indicators flash simultaneously and a warning sound is emitted Reposition the laser within its self leveling range Self leveling Height Change HI Alert Once turned on the unit automatically levels itself in ranges of 8 0 8 m 10 m In order to recognize the leveling process at the measuring area and in order not to mark faulty heights during this operation the rotation stops Once leveled the unit constantly monitors its level condition The height change HI alert is activated 5 minutes after self leveling was performed and the laser is rotating at 600 min Level errors gt 30 mm 10 m put the unit into alert mode because they are generally caused by a disturbance that could lead to inaccurate measurements When entering into alert mode the prism stops the laser beam turns off a warning sound is heard and the HI Warning LED 4 flashes 2 x per second Turn the unit off and then on again To ensure your former elevation now you have to check or a2. 45 hours in rotation Alkaline batteries AIMn permit an operating time of approx 90 hours in rotation The following factors reduce the operating time frequent self leveling due to wind or vibration extreme temperatures old rechargeable batteries or rechargeable batteries with memory effect using batteries of different capacities Remove all batteries at the same time Never use batteries with different capacities Only use new charged batteries rechargeable Low voltage is indicated by the slow flashing battery indicator 5 Charging the batteries The charger requires approx 10 hours to charge empty rechargeable batteries For this charging connect the plug of the charger to the recharge jack of the unit New or long time out of use rechargeable batteries reach their best performance after being charged and recharged five times The batteries should only be charged when the laser is between 50 F and 104 F 10 C to 40 N 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 HOW TO USE THE LASER Laser Setup Position the unit horizontally tripod mount and rubber feet downward on a stable platform wall mount or tripod at the desired elevation Press the power button 1 to turn on the unit The LEDs 3 4 and 5 are turned on for 3 seconds
