Installation guide1. First, take out the parasol that needs to be installed with light string.2. Cut the length of the light bar as needed, (the lines are parallel, you can cut off multiple parts to achieve an appropriate installation length, do not affect the use of the lamp, but you can not reduce the main line, otherwise it will cause product damage.)3. Tie a cable tie (with 30 cable ties) to the skeleton of the sun umbrella, so that the light bar can be fixed on the umbrella skeleton4. Install three No. 5 batteries (without batteries) for the battery box, use the remote control to control, the light bar can work5. If there is no battery, you can also use USB (USB cable provided) to connect, the lighting effect is the same6. The installation is very simple, and there are instructions in English
