2.8 Battery Replacement
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 the CPU board battery includes time
and date, truck and tare memory, and onboard database
information.
Use Revolution III
™ to store a copy of the indicator
configuration on a PC before attempting battery
r e p l a c e m e n t . I f a n y d at a i s l o s t , t h e i n d i c a t o r
configuration can be restored from the PC.
Watch for the low battery warning on the LCD display
and periodically check the battery voltage on both the
CPU board and on any installed memory option cards.
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 ten years.
Replacement Procedure
For best results, replace the battery while in weigh
mode and with AC power applied. Use care not to
bend the battery retaining spring.
If the battery must be replaced with power removed, do
the following immediately after restoring power:
1. Place indicator in setup mode.
2. Go to the Version menu and press the RSConfig
softkey. If connected using Revolution III ,
configuration can be reset by using monitor
mode to enter the RESETCONFIGURATION
command followed by the RS command.
See Figure 2-3 on page 9 for CPU board battery
location and orientation (positive side up).
WARNING
Risk of explosion if battery is replaced
with incorrect type. Dispose of batteries
per manufacturer instruction.
