Yesterday the red, green, and blue alternated, but this morning the blue does not work
Congrats on your new light. I dont own one, and dont know what the factory defaults are, but will try to help with general Anduril concepts.
1. Aux lights can be on low, on high, blinking, or off.. to move through those options, do 7C to advance one step at a time. I dont know which condition your light arrived in by default, but the choices are in a loop, just keep doing 7C until you get to the setting you want. I caution you Not to choose the high brightness, it has unhelpfully high power drain. I use Low, which is good for me to find the light in the dark, on my nightstand.
2. RGB lights have 10 different color options, to move through those options, do 7H and release the button on your chosen color (the last two are a bit confusing, you may need a little trial and error to tell them apart, as LRJ88 explained, one is disco mode, where the colors just cycle for no reason except to be colorful, the other is actually a Voltage color display, which may be what your light arrived in my default).
I set my Aux to Red, because it suits my nightstand application, where I dont want any Blue light. I do not use Voltage color display (nor random disco).
There is nothing you need to do, to exit those options, they simply remember the last selection, when you release the button.
Some lights arrive in Simple mode, which does not allow changing some options, for example
3. Post-Off Voltage Display is a special voltage color display for just 4 seconds after the main LED gets turned off. I do not know if it is enabled by default in your light. If after doing item 1 until reaching off, the Aux still come on briefly after each time you turn off the main LEDs, then it is active. It can only be turned off by first going to Advanced Mode (by doing 10H from Off).
I dont know if your light arrived with Post-Off Voltage Display enabled, but if it is, to disable it the process is:
do
3C from Off, this starts battery check blinks, while blinking
do
7H and release the button after the 2nd flash.
then do nothing (
0C), just wait for the flickering process to finish, and the light resumes blinking out battery voltage.
Now do
1C to end battery voltage blinks.
done
here is the latest
online manual, you may want to scan through it, just to expose your mind to all the possibilities. Dont try to memorize any of it.
and here is a cheat sheet with Red arrows at those 3 Aux features settings commands: (the chart might make the most sense after reading the manual first)
let me know if that helped, and if you have other questions ;-)
