If You Run Into Problems
One useful way to find the source of problems is to isolate your system to the smallest size
wherea the problem still occurs and then note all the symptoms. This serves to eliminate areas
not involved in the problem and make finding the problem easier.
Once you’ve noted problem symptoms, look through the following table and see if any of the
symptoms are listed. If so, check the items listed. If you later need to call for customer service,
let them know all of the things you’ve tried and when and how the symptoms appeared.
