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.
