Blinking of the left red indicator when you dial a code shows that it is necessary to replace batteries. From the begining of battery dischage indication to lock turn-off the lock can be unfastened with a code no more than 100 times.
To replace the batteries needs to make the following actions:
On the internal keyhandle, in its bottom side, open the cover and turn the cover screw with a screwdriver, no more than 4 mm wide, counter-clockwise. Because of a spring the cover will open.
Put out four batteries and insert new ones according to the picture on the keyhandle internal part.
Close the battery case cover backward.Make sure that the lock operates correctly both with a code and with a mechanical key.At the correct function entering the right light-emitting diode of the keyhandle indicator will blink oft-reccuringly.
At the wrong entering there is prolonged lightening for a second.
