2. Insert 2 new AAA batteries.
3. Close the battery compartment cover.

Warning:

• Incorrect usage of batteries may cause leakage or explosion.
• Pay attention to the polarity when installing batteries.
• Do not use batteries from different brands together. Do not mix new and used batteries. Doing so may shorten the battery life or cause leakage.
• Remove the batteries or replace them with a new pair when the batteries are depleted in order to prevent battery leak in the battery compartment.
• Do not touch the leaked substance from the batteries in case of a battery leak. Doing so may damage human skin.
