    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.

    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,

    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

    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.
