When the Sapphire Supreme light is turned on, the light defaults to the Standard Curing Mode of 5 seconds. Time settings for buttons 1-4 are adjustable, but are defaulted to the following pre-set curing timers:
#1 – 3 seconds
#2 – 5 seconds
#3 – 7 seconds
#4 – 9 seconds
Each of the timers are adjustable up to 10 seconds. If Key 2 is pressed after power-up, it will change from 05 to 06 seconds and each time key 2 is pressed another second will be added to the curing time.
