 Most Telephone Entry Systems can be programmed from the front keypad or remotely from an off-premise location using any touch-tone phone. TES Remote Programmer streamlines the often cumbersome remote programming process by providing data entry screens and automated dial-in options.

-By default, TES Remote Programmer is configured to work with the [DoorKing (DKS) 1802, 1802-EPD, 1803, 1808, 1810 and 1819](http://www.doorking.com/telephone/) systems, additional [configurations](#configurations) can be created for most systems supporting remote programming.

+### Directory Code

 Please note that all default configurations are set for 3-digits directory code length. If your system is setup differently, you will need to modify the [default configuration](app/src/main/res/raw/) and re-import it. Look for all `Directory Code` fields and modify their `size` attributes accordingly.
