'95 Accent Radio

Hi,
Can anyone please tell me how to re- enter the radio security codes. I
believe that I need to disconnect and reconnect the battery and then punch
the code in but If I use the numbered radio buttons nothing seems to happen
e.g. if I press 5732 in order , I get no response.
Thanks
John

 

Once you've made three unsuccessful tries, you need to leave the radio on
for a half hour. Then you have three more tries. You enter the code by
pressing it in by the number keys on the radio. If your code were 5632,
you'd press 5, then 6, then 3, then 2.

 

Thank you very much,
I didn't know about the half hour , I'll do that now. Thanks again
John
