1991 300d Need help with radio

Hello Guys
Today I had to put a new battery the the 300d first one since I got it 3 years ago.
Radio did not power up, I pushed the power on button. I expected it to come up wanting the code.
Which I have, but no it just flashes wait-wait-wait-wait this goes on for ever, So tell me my friends
what have I done wrong. Thanks to all..............Norm

You triggered the anti-theft function. You need to put in the 4 digit security code to re-activate the radio.

Crazy, Becker Anti Theft Logic

Recoding Sequence:
To recode a radio, follow this procedure:
1.Turn ignition key to lock position one.
2. Turn on the radio. The word CODE appears on the display.
3. Enter the first digit of the radio's antitheft code as it appears on the code card.
The word CODE will disappear and the first number that you have entered will be displayed.
4. Enter the rest of the antitheft code. Each number will be displayed when it is keyed in.
5.When all four antitheft code numbers have been correctly entered, radio operation will resume.
The station stored at push-button 1 FM will play.

Incorrect Code:
If an incorrect antitheft code digit is entered,continue to enter numbers until four are displayed.
The word CODE will appear again. The system allows two more recoding attempts.
After the third incorrect attempt, the word WAIT is displayed.
A period of 15 minutes must pass and the word CODE must again be displayed before recoding can be successful.
The radio must be left on during this period.
This measure is meant to prevent a thief from recoding the radio by randomly entering numbers.
If the correct antitheft code has not been entered after three separate attempts-
and therefore after two 15minute wait intervals - the radio will lock for 24 hours to prevent any further recoding attempts.
The radio must be left on during this period in order for it to re-enter the code mode
