1. The batteries in safes generally use high-quality AAA leak free alkaline batteries of size 5. Pay attention to the positive and negative polarity of the battery when placing it, and place it according to the positive and negative polarity markings on the battery box. If the safe is not used for a long time or if an external battery is used for a long time, the battery should be removed from the battery box.

2. Use the safe indoors at room temperature. Safe cabinets exposed to humid and corrosive gases, or strong sunlight and ultraviolet radiation, can cause surface paint cracking and discoloration, plastic parts discoloration and aging, surface rust and oxidation, unstable electronic component performance, and easily lead to malfunctions. So in order to better maintain the safe, it should be placed indoors at room temperature to ensure its normal use.

3. If there are stains on the surface of the safe, it cannot be cleaned with chemical solvents, but should be wiped with a clean cloth dipped in a small amount of cleaning agent. If corrosive chemical solvents are used to scrub the surface of the safe, it is easy to cause the paint on the surface to crack, discolor, oxidize, and rust. Therefore, when cleaning the safe, it is important to use a clean cloth dipped in a small amount of cleaning agent to ensure that it is not corroded. It is also important to prevent the safe from being contaminated with corrosive liquids or placed in an environment with corrosive gases.
