EM-50: Initializing the EM-50
The following procedure will clear the internal memory and reload the factory settings.
Caution: All User information will be lost when you reinitialize the EM-50. Be sure to first back up any information you wish to preserve.
1. Turn the EM-50 off.
2. While holding down the WRITE button, turn the EM-50 back on.
Note: Never turn off the power during a Factory Reset. This can result in corrupted internal data, and prevent you from turning on the EM-50.
