Clock broken won't stop beeping?

Hi ,
I have a rangemaster classic 60 single cooker,
It has 3 button clock which is broken im able to use top oven and hob but it won't stop beeping and I can't use main oven?
Iv searched everywhere for replacement clock even through rangemaster and can't get one.
After reading on here I'd like to know can I disconnect my clock and get all working without it?
Please help
