How to use
Install the lock on the door or gate following the manufacturer’s fitting instructions and ensure correct orientation and secure mounting. Set or change the access code according to the supplied procedure, then operate the lock by entering the code sequence through the mechanical controls. After entering the correct code, rotate or actuate the handle or knob to open; relock by returning the mechanism to its secured position. Periodic inspection of mounting fasteners and lubrication of moving parts will help maintain reliable operation.
