Installation Tips:

1>.User needs to prepare the soldering tool at first:

1.1>.Small Phillips screwdriver

1.2>.Small wire cutters

1.3>.Fine tip soldering iron(Recommend using a fine point soldering tip)

1.4>.Good quality small gauge solder(recommend no larger than 1.0 mm)

1.5>.Magnifying glass

1.6>.1pcs 18650 battery

2>.Please be patient until the installation is complete.

3>.The package is DIY kit.It need finish install by user.

4>.The soldering iron can't touch the components for a long time(1.0 second), otherwise it will damage the components.

5>.It is recommend building the project starting with the lowest components first and working up to the highest components. This is a common practice as it makes it easier to hold the low components on the board while soldering

6>.Pay attention to the positive and negative of the components.

7>.Strictly prohibit short circuit.

8>.User must install the LED according to the specified rules.Otherwise some LED will not light.

9>.Install complex components preferentially.

10>.Make sure all components are in right direction and right place.

11>.Check that all of the LED can be illuminated.

12>.It is strongly recommended to read the installation manual before installation!!!

13>.Please wear anti-static gloves or anti-static wristbands when installing electronic components.
