OrionC1499; 1499; 2099TXStuck in st/by (timer light?)Fit EPROM Pcb (supplied FOC by Orion) fit 1K res across pins 4&8 of IC1099 (not marked as such on my set but only 8 pin chip close to Cpu and back up batt), Fit silicon diode across pins 1&3 of system reset Ic1002 (again marked differently on my set as T1002). Then carry out checking of EPROM settings via on screen display, Instruction sheet supplied by Orion (DAL). Contact Orion (DAL) on Fax 01923 231597 (you must send set Model/Ser no on company headed paper to get FOC issue of the small Pcb which you then use for other sets with this fault).
