Light Flashes on Third PIN Digit
From X10Wiki
[edit]
Question
Why does my light turn on and off when the phone rings and the TR16A is plugged in?
[edit]
Answer
The TR16A Telephone Responder can flash a selected light or lights anywhere in your home when the phone rings (useful for the hearing impaired). Any Module(s) set to the same number as the third digit on the security code dial (on right) flashes on and off when the phone rings. If you do not want any modules to come on, you will need to set the third digit to a Unit Code that you do not have any modules set for.
