CHANGED BATTERY IN 93 SAAB 900 NOW MY RADIO WON'T WORK

Someone put the wrong security code in the radio. Hold the DNR button down and the code will clear. Be sure you have the correct code to enter after clearing the current one.

Sounds like your Clarion needs its four digit security code reentered! Hopefully you have this..... if not, your SAAB dealer might be able to provide it, given the VIN. Otherwise, you're going to be unlucky. (:

Assuming you have the code, first remove the radio to initialise the sequence. Re-install the radio, turn on th ignition, key in your code number using the station preset switches (1 to 6) and the unit should then operate.

If you make a mistake in entering the number, finish entering all four digits, then press and hold the BAND switch until CODE appears on the display. Then more carefully, enter the correct code.

If you get it wrong for four consecutive attempts, you'll be locked out for an hour of 'radio on' time, after which you press and hold BAND as before etc.. You then get one code attempt an hour until you get it right, to discourage guessing the number!

Good luck!
