Features: Thank you for choosing our LED light curing machine. This instrument takes the high power pure blue LED as light source. It's thenew light curing machine which used with enhanced modespot opticalfiber light sticks. 1.LED light curing machineadoptsthe light-emitting diodes Blue-ray, it cancure the resin with the wavelength of 420-480nm, and be used to repair the teeth in the department of stomatology; 2.There are three solidification working light modes: strong light mode, flashing light mode, gradual light mode. 3.The light-emitting diodeshas long life, which can greatly reduce the costs of future maintenanceof the machine; 4.Its does not produce any heat when running, so no needto cool it with fan, thus, it is free from the annoyance of noise andvibration of traditional machines; 5.Thehigh capacity lithium ion batterycan lastabout130-200 times after being fully charged(4-8 hours). 6.Intelligentbattery detection circuit function:when batteryis low, itwillalarm and the light will flash. 7.Lightweight and two-stage design, first low-lightirradiation, and then glare rapid curing. 8.This can inhibit the exceive contraction of the resin surface, avoidcracks between cavities edge. Operation 1. You can set working modesand working time(5s-40s)on this machine . 2. working time setting Pre the"M" button for a while, when hear"di di"and light shine,pre"P"button to choose the time, 5s- 40s is available. Whenyouhear "di di" againand light stopping shinning,thetime setting is done. 3. Working mode setting Pre button "M"to choose working modes, choose the mode you need.
