2.10 Battery Replacement
CAUTION
Risk of explosion if battery is replaced with incorrect type.
Dispose of batteries per manufacturer instructions.
The lithium battery on the CPU board maintains the real-time clock and protects data stored in the system RAM
when the indicator is not connected to AC power. Data protected by this battery includes time and date, IDs, and
configuration information. If any data is lost, the indicator configuration can be restored from the PC. Watch for the
low battery warning on the LCD display and periodically check the battery voltage on the CPU board. Batteries
should be replaced when the indicator low battery warning comes on, or when battery voltage falls to 2.2 VDC.
Life expectancy of the battery is 10 years. Use Revolution to store a copy of the configuration before attempting to
replace the battery.
For best results, replace the battery while in weigh mode and with AC power applied. use care not to bend the
battery retaining spring.
