Twenty-one electronic safe
Keep invoices, warranty cards and other accessories in a safe place. The user manual records the product numbers and passwords of safes and cabinets. The factory builds product technical files based on product numbers and product models. According to which users can retrieve the passwords of safes, this is particularly important for mechanical safes. Note that these accessories must not be locked into the safe. If the safe cannot be opened, there will be no emergency opening method. If it is a safe with upper and lower double doors, it is recommended to mark the keys of the upper and lower doors to avoid the failure of the key stuck in the lock cylinder and cannot be rotated or pulled out after misuse. After the password is modified, it is best to write it down in another notebook, so as not to cause the trouble of unlocking after forgetting it. The key and the password must be kept separately, which is more secure.
Use environment
The safe is suitable for indoor use at room temperature. Used in a humid and corrosive gas environment, strong sunlight and ultraviolet rays can cause cracks, discoloration, discoloration and aging of plastic parts on the surface of the safe, rust and oxidation on the surface, and unstable performance of electronic components, causing malfunctions .
Maintenance
After the surface of the safe is stained, it cannot be scrubbed with chemical solvents, and it can be scrubbed with a clean cloth dampened with a little detergent. The protruding door bolts and the rollers of the drawer can be lubricated with a little lubricating oil (household cooking oil is also acceptable), and a little pencil core powder (graphite) can be injected into the key lock core to make the key insertion and removal and rotation easier. The safe is a kind of anti-theft device. If the sense of responsibility and attention is added in the use process, the anti-theft coefficient of the safe will be greatly improved.
①When turning the mechanical code lock, you need to calmly turn it slowly. Don't turn it vigorously. At the same time, remember the direction and number of times. ②It is best to set the password when the safe door is open. After the password is set, you should enter the new password several times and confirm that it is correct before you can lock the door. ③Do not lock the manual and emergency key into the safe. ④When using the alarm, do not arbitrarily adjust the internal switches and electronic components. If the sound becomes smaller, it indicates that the battery is exhausted. Replace it in an emergency. If a false alarm occurs, the sensitivity can be appropriately lowered. ⑤In order to ensure the reliable fixing of the safe, the cone pin in the expansion nut must be hammered until the nut expands and tightens. The nut is sufficiently strong in the wall hole. ⑥The safe must be fastened to the concrete wall. ⑦When the external battery is used for a long time, the battery should be taken out of the battery box.
