How can I reset the grand total on my BA374E Timer or Clock?

[VonJack]

To reset the grand total on your BA374E Timer or Clock, follow these steps: First, press and hold the buttons for approximately ten seconds until "CLr. no" appears on the display. Next, use the appropriate button to change the display to "CLr. YE5". Finally, press the button again. This sequence will reset the grand total to zero. Keep in mind that if the "Glr gtot" sub-function is enabled within the LoC r5Et configuration function, the grand total might reset to zero if the buttons are held for an extended period. For comprehensive details on configuration options and functions, always consult the complete instruction manual for the BA374E.
