How to change the EHS mode

To change these settings, programming mode on the base station must be activated. To do this, move all the DIP switches into the down position. Please note that the images below demonstrate this procedure on a DW base station. On an SD base station, the DIP switches and reset button are located on the underside. 

Once all the DIP switches have been moved into the down position, pressing the reset button will cycle through the different setting options. The various settings can be recognised by the different flashing LEDs, as can be seen on the graphic below.

Once the correct setting has been chosen, return DIP switches 2 through 6 back to the up positon. The base station will then undergo a reset and upon completion will now be programmed to the new EHS mode.
