Using the Emergency Battery

1. When Lock Fails to Operate Due to Discharged 

     AA Batteries

If the batteries are not replaced after their replacement time comes, they will be 

completely discharged and the doorlock will not operate.

2. Using the 9V Battery

Buy an emergency 9V battery at the nearest 

store. 

3. Opening the Door Using the Emergency Battery

Place the card or key tag on the card reader, or enter the password, while the 9V battery 

is connected to the external power contact of the outdoor unit.

As the alkaline batteries offer longer life, they are recommended 

than the manganese batteries or rechargeable ones.
