There is a LED Test Program available to check if all the LED’s are functioning correctly.
Press “Up” and “Down” simultaneously to activate the Test mode.
The first Test mode appears, which is all LED’s-colored Red.
Use “Up” and “Down” keys to step through the 10 Test modes which is consecutively:
Red, Blue, Green, Yellow, Light Blue, Purple, White, Rainbow, Turning Rainbow (Clockwise) and Turning Rainbow (Anti Clockwise).
(Take care with entering Test mode with high brightness, as soon as you select white color, the maximum power is consumed which might be to much for the power supply and the Clock will hook up. No other choice to unplug/replug it if this happens, there will be nothing damaged)
Press “Esc” or “Enter’ to exit the Test mode.
Else after 60 seconds Test Program will exit automatically.
