Installation Notes

(1) Please read the manual in detail before installation.
(2) Before installation, make sure that the working voltage of the LED rainbow tube light matches the output voltage of the switching power supply you purchased.

(4) It is strictly forbidden to cut off the male and female head wires with electricity, so as not to burn out the lamps in the short-circuit.
(5) LED rainbow tube light with control must comply with the male in and female out, and the direction of the signal must be connected in series when connecting the lamps.
(6) This lamp is forbidden to be disassembled without permission, if it is disassembled without permission, our company will not bear the warranty.

Simple troubleshooting

(1) When the lamp does not turn on when it is powered on: check whether the switching power supply has a working output voltage, or whether the working voltage of the switching power supply is normal.
(2) After the switch power supply works normally, the lamp still does not light up: check whether the signal line of the lamp is connected incorrectly or whether the connection is normal, and check whether the controller works normally and whether it has been powered on.

(3) The above work is normal, but the lamp still does not light up: check whether the SD card of the controller has been inserted, and whether there is a program in the SD card.
(4) The lamp jumps or flickers: Check whether the negative pole of the lamp is connected in parallel with the negative pole of the switching power supply including the GND of the controller.
(5) If the above inspection is completed, it is still out of control, please contact our sales staff to deal with it.
