Very confusing directions in the 1200 manual. 4* on for unit code 4. Ok, makes sense. Then the manual states: 16# to turn off for unit code 16. So I'm thinking they just chose two different unit codes as examples and since mine are set at 2, for the key chain remotes, 2 should work. I call, enter (after PIN) 2*, and nothing. Try it again with 4* and it replies "lights on". Of course nothing happened since my code is 2. Then I enter 4# and it replies "lights off". So two questions: If I'm going away do I need to set the modules to 4 and why the heck do they even mention 16 or am I missing something here? Thank you!
