TROUBLESHOOTING

envisaged. Given that the malfunctioning may have various underlying causes, it is necessary to first of all examine the apartment unit or
front door unit where the problem has arisen, then moving on - if necessary - to the other system components.
If all the following checks produce a positive result, but the problem persists, try replacing the device where the malfunctioning occurs.
