Hi, I'm an electrician, and I'm trying to program a customer's Doorking 1812 keypad. It's used for a gate, and when somebody drives up to the gate, they press 'call', which dials the phone at the house. The customer needs to be able to press a number (usually '9'?) to open the gate.
I'm having trouble programming this number. Any ideas? I have the owner's manual, but it's not real clear. Any help is appreciated.
Thanks!
Andrew
