What to do if the Doortec DOORMAN SDO1 wall button works but the transmitter doesn’t?

If the wall button for your Doortec Door Opening System works but the transmitter does not, it's likely that the transmitter program is lost or the transmitter battery is flat. You can re-code the transmitter, referring to section 6.4, or replace the transmitter battery with a new one.
