Real Time Clock Battery Low

What does 46 mean?

The voltage of the Real Time Clock (RTC) battery is low, indicating it needs replacement. A low RTC battery can lead to loss of time and date settings upon power cycle, affecting data logging and time-dependent functions.

• The internal Real Time Clock (RTC) battery has reached the end of its service life due to normal aging.
• The drive has been powered off for an extended period, leading to a significant drain on the RTC battery.
• A rare fault in the RTC battery charging or monitoring circuit on the control board.
