Buffer Battery
The exchangeable buffer battery ensures, that the clock time (RTC) and SRAM data of the
HZS 772 is preserved in the absence of a supply voltage. A lithium battery is installed at the
manufacturer.
After delivery of the HZS 772 and storage of one year, the lifespan of the battery reaches
10 years, if you make sure, that the device mainly is in operation (supply voltage is on).
We recommend however, that the battery be replaced every 8 years to ensure optimal
performance.
ATTENTION: If the device is not supplied for 2 years, the battery is empty.
