Description Here's how it works
Routine Troubleshooting for YL-99 Digital Lock
1. De-energized
(1) Inspect whether the plug falls off or plugged in oppositely;
(2) Inspect whether AAA alkaline batteries are installed;
(3) Inspect whether the positive and negative electrodes of the batteries are opposite;
(4) Inspect whether the wire and power line of the battery holder are broken.


2. Incapable of nlocking with New Installation and Charging
(1) Enter the correct password and press “#”, then rotate the handle and open the door before the unlocking beeping stops. (Please note the key words: 1. Enter the correct password; 2. Unlock before the beeping stops.)
(2). Set the password correctly: the management code is combined with 2-15 numbers headed with “0”, but the second number can’t be “0”; The user code can be a random combination headed with “1” to “9” and followed by “2” to “15”.
(3). Distinguish the correctness of the password. There will be a beeping of 2.5s if a correct password is entered ended with “#”. If not, that means the password is wrong. Please reset the password. (The password can be reset to the factory defaults as management code of 0123.)


3. Broken Down in a few Months after Using
(1) It must be caused by the use of bad batteries. Good alkaline batteries like carbon-zinc batteries work for about 1 year. The issue could be fixed by changing the batteries.
(2) How to judge the under-voltage of batteries: when continuous beeping (10 times) is heard after the door is unlocked with the correct password, it means the batteries are under-voltage. Please change the batteries in 15 days after the first beeping is heard.
