Choose the led controller that you want to match, then turn off the power for 10 seconds,
then turn on the power, within 5 seconds when you turn on the power, press the button
"Group ON" of the group you want to assign, the lights connecting to the led controller will
flick for 3 times, then this group is match successfully. The other groups can also be set by
the same method.
Remark：One led controller can only match one group in the same remote, but one remote
group can match countless led controllers, and one led controller can match 10 remotes.
2. Clear the code and regroup:
if the room layout are changed, or you want to make a little adjustment upon your fond, then
you may want to change the previous groups, before you change the groups, you need to
clear the code, the method is as following:
Choose the led controller you want to clear the code, turn off the power for 10 seconds,
then turn on the power again, within 5 seconds when you turn on the power of the led
controller, press the button "ALL ON" for 6 times, the lights connecting to the led controller
will flick for 6 times very quickly then the code is cleared successfully.
After the code is cleared, the method of setting the group is totally the same as the principle
of "matching the code and grouping"
If you want to dim all lights controlled by remote at once, press the button “ALL ON” firstly; if
you want to do this with individual light, press the associated button “Group on” firstly, then
choose the mode, color or brightness.
