2. The most recent event code is displayed, and the unload button now functions as a scroll button for additional event codes.

   Note: At any time in this procedure, the tape drive returns to normal operation if you perform no scroll action within 15 seconds.

3. Press and release the unload button for the next most recent event code. You can display up to five total events using this method.

4. After you display the final available event code, the next button press causes all LEDs to flash indicating that the next eight hex characters displayed are the detailed error code of the most recent event. The first character is either a hex E (error) or a B (bug check). When you display the last (eighth) detailed error code digit, the next button press returns the tape drive to normal operation. All indications are a four bit hex value.
