How do you change the program on the timer? Right now pre set for 60 seconds and I want to change it to 30 seconds. please can you let me know asap. Thanks John


To program, press and hold the PRINCE CASTLE LOGO for eight seconds, a beep will sound and the CHANNEL/FUNCTION DISPLAY will read SEL CH/LOGO = QUIT. Select and press the timer channel to be programmed. The LED indicator for the selected button will turn yellow and a beep will sound. The CHANNEL/FUNCTION display will read, CKT=COOK TIME with up and down arrows. The current complete cook time (Factory Preset 3:00 M:S) for that channel will be displayed in the TIME display, and the time value will indicate either H:M or M:S. At this point, program in your complete cook time by using the SCAN/UP Arrow or the SCAN/DOWN Arrow button. Once you have reached your desired time press the ENTER button to store your complete cook time. Note: The Enter button must be pressed after any time changes in the cook, duty or hold functions or the the time change will not be stored. Further information can be found in the manual located under the Literature tab of this item. Thank you.

can I program this timer to beep half way through the time to indicate time to flip burgers ?


Hi. This timer can be programmed with 6 different functions, such as total cook time, 1st duty during cook time, 2nd duty, 3rd duty, hold time, and duty during hold time. Please see the manual in the "Literature" tab for more details. Thanks!

can I get timer with voltage 220


We cannot locate a 220 volt timer, but there are timers that are battery operated, like the West Bend 40005X 100 Min - 1 Second Electronic Timer (Item #: 387120) or the Rubbermaid FGR442188 White 3-Function Digital Timer (Item #: 317208). Hope that helps.
