volvo 850 sc700 radio code entry

I have a volvo 850 with an sc700 radio fitted. Today I changed the battery on the car and then went to enter the code into the radio. I entered the code given with the radio 3 times but each time it said 'error'. After the third time the display read 'off'. The owners manual states that you have to wait 2 hours before you can try again to enter the code. After several hours i have tried again but on switching on the radio the display just says 'off'. Any ideas would be appreciated. Many thanks, Roy

The radio needs to be left on ane the ignition needs to be in the acc position. for two hours. Or you could take a nice long drive.

Roy,

You might have to actually leave the radio switched on for two hours after which it will accept input again, but if it's not accepting the code that 'came with radio', then something is wrong, is it the original radio for the car? If the radio is anything like some ford ones I've come across then the next lockout will probably be exponentially longer, i.e. 4 hours.

Hope this helps, Ken

the key must be on for @ least 2 Hours in position 1 then the radio will show code when it is ready I would remove the radio write down the serial # & model # & the Volvo part # a stop by your local Volvo dealer & have them get the correct code for your radio Glenn

Thanks everyone, will try the two hour wait and try again, failing that I;ll get in contact with a volvo dealer. Many thanks, Roy

If the input code message is still there then what about the possibility that when changing the battery you have blown a fuse within the radio itself. Now I dont know about the 850 but I have had this on a 740 with Volvo radio - exactly the same symptoms. I removed radio and inside at the rear is a small fuse - replaced, re-entered code and all was well again.

Just a thought.
