enigma 1 run event on timer

Hope someone can help me. Downloaded a new enigma1 image for dm500 with auto bouquet and epg updater. the only other image iv seen to do this is the commando image 14.7 great image but problem with lip sync on this image which was not there on 14.5. But any way I am looking to put a timed event to do the epg update automatically on the pli image as I have just pick up this image and never had any problems with lip sync and with the auto bouquet and epg which has to be done manualy and dose not catch the event that is on at that time.
