sary check.
Be sure to wear safety gloves and goggles when you repair the product in order to prevent

Reconnecting the Ground Wire
1. First, check if the short circuit has occurred in the main body.

work on it.
3. If you need to test the product while power is being applied, be sure to wear rubber
gloves to prevent electric shock.

prevent them from falling. Especially, be careful of thin objects (e.g. glass panel).
