Please use DC5Vonly;
There are direction arrows on the PCB, arrow direction for connecting next reel strip;
GND not only for power wire, also as signal wire, need connect to both power and controller;
The Max distance between strips is 5m-10m, need use amplifier when more than 10m;
Every 5m strip need re-connect to power supplier, avoiding voltage drop;
Keep the surface of installation place clear and smooth, avoiding the strip fall off.
DO NOT press the LED;
DO NOT attempt to make sharp bend with the strip;
