Battery Replacement
The 3V, coin type lithium battery (PN 69290) 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, onboard
database information, and setpoint configuration.
Use
iRev
to store a copy of the indicator configuration
on a PC before attempting battery replacement. If any
data is lost, the indicator configuration can be restored
from the PC.
Note
Memory option card data is also protected
by a lithium battery. All database
information stored on a memory card is lost
if the memory card battery fails.
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.
See Figure 2-7 on page 11 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.
