The 7500E calculates totals and prints IN and OUT punches in the columns. If the 7500E is showing an E-52 Error, the button function setting may be set improperly. To correct the problem:
1. Verify the button function setting.
2. Adjust the setting to either Optional or Disabled.
If it is preferred to have this setting as required, employees must press the IN or OUT button before inserting the card.
