Clock

±60 seconds per month (deviation at room temperature and power is OFF). Variations in operating conditions and battery life can cause clock deviations from -380 to +90 seconds per month.

For systems where this level of precision is insufficient, the user should monitor and make adjustments when required.

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, leave this product ON for at least 5 minutes, and then set 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 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.
