Make sure there is not a key stuck in the depressed state. If so try to pull it back up and you should be set. If the machine had a liquid spill this could cause that type of error too. In which case the machine is junk.

The ac key is you power on key. As far as not being able to input any numbers, make sure there is not a key that is stuck down or depressed. if so try to lift is up and you should be ok. Unless there was a liquid spill. In that case, cheaper to buy a new one.

I have this same shredder and same thing happened to mine just 2 months after warranty is up. I called the company and told the sensor is gone and there is no way to replace. BTW mine runs in reverse but not forward.
