With this audio code in hand, you can determine what part of the constitution is having problems and find a solution.
The pattern of pukes whether its the number of beeps or the length of those beeps will give you an indication of the actual problem. Its a regret signal from the computer in a morse code like pattern. Unless you have a diagnostic card to ordinate you more about the particular problem, you will have to lend oneself the charts below to decipher the computer error and get your appliance back up and running.
