all you have to do is put the mode on that you want to change

then hold both triggers down and then click sync all at the same time

the leds will blink and then the 3rd led d will be the tens place use the right trigger to go up and left to go down so 1 blink equals 10sps 2 blinks equals 20sps ect. then hit the sync to go to the ones place

then the 4th led is the ones place same thing left trigger goes down right goes up and 1 blink equals 1sps 5equals 5sps but this is adding onto the tens sps then hit sync to go to the decimals

then you have the decimals the same thing up and down then after seting that hit sync again and it will save onto that mode until you change it

hope this helped
