DTS Systems or older (black boxes)- The most common problems are with address and mode settings. Try to isolate the problem by setting up the components one at a time in a controlled environment. Start with all of the components powered off, then turn the Timer on. Slowly go through the options checking the mode and the address. Then power on the other units one at a time (checking addresses) until the system setup is complete and working or the problem has been reproduced. Once the problem has been isolated, refer to the trouble shooting guide for instructions on fixing the problem.
