4. Periodic Maintenance
4.1. Real-Time Clock Battery
The CPE330 is shipped with a real time clock (RTC) battery
installed (see Figure-3). Over time, this battery will need to be
replaced. No action is required during initial installation.
Should the RTC battery fail, the CPU date and time will be
reset to 12:00 AM, 01-01-2011 at start-up. The CPU operates
normally with a failed or missing RTC battery; however, the
initial CPU time-of-day (TOD) clock information will be
incorrect.
There are no diagnostics or indicators to monitor RTC battery
status. The RTC battery has an estimated life of 5 years and
must be replaced every 5 years on a periodic maintenance
schedule.
For complete procedure, refer to Replacement of Real-Time
Clock Battery on CPE330 in PACSystems RX7i, RX3i, & RSTi-EP
CPU Reference Manual, GFK-2222V or later.
