Need Help - Becker CDR 210 Code Reset

[motolz]

I had to disconnect my battery and obviously, my Becker CDR 210 is looking for a Code.
Using a code generator, I tried code 4818 but after entering the code, nothing happens but the first number blinks. Is there something else I have to do or is this the incorrect code?

If anyone has a generator, I would appreciate if you could look up
CDR 210
MO = BE2282
SN = W5021438
EC = 106

If not, I will contact becker directly.

I appreciate any advice or help.

Thanks,
Tom

Just an FYI to anyone interested. After entering the code, you must push the down arrow on the right hand control. The code generator on line worked, but like a previous suggestion, I had to go up two numbers.
