has always recognized that there are features and functions that our
products don't have. In response we've created a manual detailing the
in-field customization of our units to do some of the more
frequently requested functions. Called the "Modification Manual"
and now in it's fifteenth year, it has been an invaluable source of
knowledge for in field technicians. It is available free of charge for the
first time here.
All modification are in PDF format and are broken down into 5 levels, based on their difficulty: Level 1 - Easy - Wire Connection
Only Please note that modifying a unit will not void it's warranty unless while doing the modification you damage the unit. Aiphone is not liable for any damaged caused during modification. Modifications should only be performed by a person with the skills and knowledge necessary to successfully complete the modification. | |
