If the sequence starts with no errors but stalls check that the Pause Mode is set to Manual Only. To check this: Abort the program and press the (S3)<Setup> key, press the (S4) <Pause Mode> key until you see Manual Only.
If the sequence starts with an error (i.e.: Line: 1 Program Error: -4 Zero length sequence) then there is no sequence program loaded in that slot. To load a sequence program press: (S3)<Setup> (S1)<Load From Disk> and select the .prg file that you want to load using the up/down arrow keys, press (S1)<Pick> to load the file. When done loading press (S8)<Return> and (S1)<Start> to restart the sequence.
