Ha there! I've been changing them:
- be sure the light settles to approx. room temperature
- go to the temperature readout mode (called TempCheck on the diagrams)
- click quickly 4 times to get into thermal configuration mode
- the light should flicker, like strobe mode - you only got a few secs to start, but while it's strobing, click the # of times you want to set the temperature to. For example, click 20 times to set 20C. These clicks don't have to be quick - it's just the total # of clicks that count.
- Once you stop clicking, it will timeout in a few seconds, then the strobe will start again. Now you want to set the max temp for thermal regulation. If you want to max it out, click 40 times (sets 70C as the max temp). Again, it will timeout after you stop clicking, and don't worry if you click more than 40 times - it will still act as if you clicked 40 times to set the max temp to 70C.
You can confirm the current temperature right away, because as soon as the 2nd strobe finishes, the light returns to blinking the current temperature. If you set 20C, it should now blink out 20 or 21 or so. Unfortunately you can't confirm the max temperature setting.
Now if this 70C doesn't work for you, you can do some cheat'n -- . Repeat the steps above, but instead of setting 20C as the current temperature, click only 5 times for 5C. This will effectively raise your max limit to 85C, though your current temperature will be calibrated 15C low. So the good thing about this is the light will start to temp regulate at what it thinks is 70C but is really 85C.
Let's see if that works...
