Replacing the Primary Battery

Backup clock data uses a Supercapacitor (electric double-layer capacitor) for power. When the voltage from the Supercapacitor is low, clock data is lost*1 when this product is turned OFF. The average period for backup is as follows:

Initial: approximately 100 days

After 5 years: approximately 30 days (when used with an ambient temperature of 25 °C [77 °F])

*1 If clock data is lost, a clock data error message appears when starting up this product. When this happens, please set up the clock again. Refer to your screen editing software manual on how to set up the clock.

By connecting the optional backup battery (part number: HMIZGBAT) for clock data backup, you can maintain a backup period of up to 5 years or more (when used with an ambient temperature of 25 °C [77 °F]). However, as the battery expires after 5 years, we recommend regularly changing the battery every 5 years.

NOTE:
  • Because the battery for clock data backup is a lithium battery, its performance degrades based on the temperature. As a result, when the battery's ambient temperature is higher, the backup period is shorter.

When the voltage of the Supercapacitor drops at the same time as the voltage in the battery, clock data is lost when power is disconnected. If the clock data error message appears while the battery is connected, the battery is low and requires replacement.
