hello,this is my first post,i have a arrow 500 year 97 and when i start up the control it ask to reset the time and date and wont load any further ,it times out after about 10 minutes,and it goes to the normal screen ,when i go and try to access time and date it wont let me in becouse of a security password is needed to acess it .i recently bought the machine so i dont have the old password,does anyone have any experiance with this,i hope i have explained the problem clearly ,thank you
