Symphony single slot cd (front loading) player in a fabia 2001

I have the security codes.

Stereo went into safe mode for no apparent reason, no battery issue, fuses intact including the fuse on the back of the unit.

Made an incorrect attempt to enter the code, so I should get attempt 2 after 1.5 minutes.

Unit is stuck on displaying

2 SAFE

meaning I guess 2nd attempt, however i never get to enter the codes, the unit just sits there, waiting 24 hours even made no difference.

Puilled the unit from the car to discharge, pulled the battery, it wont allow me to re-enter the code.

All fuses verified as intact, no functional issues leading up to the problem.

Any suggestions.

Cheers

as an aside does anyone know (assuming I get it up and running) where i can get a manual from pdf perhaps.

Hammer???

If you don't have the manual can I ask what method you're using to enter the code?

PREPROGRAMMED radio buttons 123456

assume 1234 as the code

press button 1 once

button 2 twice

etc

then >> more than 2 secs

worked fine when installed.

Been working for over a year.

The reason I am after the manual if any is can't get the bugger out of tp mode.
