2.8 Fuse Replacement
Fuses for the desktop and universal models of the 920i
are located under a cover plate on the outside of the
enclosure. Remove the cover plate, replace the fuses,
and reinstall the cover plate (see Figures 2-12 and
2-13).
To protect against the risk of fire,
replace fuses only with same type and
rating fuse.
See Section 10.13 on page 107 for complete fuse
speciÞcations for the desktop and universal units.
Interface board and fuse access cover
plates must be in place for use in
NEMA 4X/IP66 applications.

2.9 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, onboard
database information, and setpoint conÞguration.
Use iRev to store a copy of the indicator conÞguration
on a PC before attempting battery replacement. If any
data is lost, the indicator conÞguration 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 2-4 on page 8 for CPU board battery
location and orientation (positive side up).
