WARNING
- Make sure to correctly insert the batteries with the polarities of the batteries “+” and “-” matching the marks. If the polarities are incorrect, the batteries may explode or leak. If you do not intend to use the device, remove the batteries to prevent leakage. If electrolyte leaking from the batteries gets on your skin or clothes, wash it off immediately with water.
- Be careful not to get your hands pinched or cut when installing the battery compartment cover.
Important
- Insert four new batteries of the same type. Using different types of batteries or mixing old and new batteries may cause a failure.
