2.2 Remove Battery Tab
The backup battery on the LP3500 has a plastic tab to protect the battery against discharg-
ing before the LP3500 is placed into service.
Figure 6. Remove Battery Tab
NOTE: Rabbit recommends that the battery tab not be removed until you are ready to
place the LP3500 in normal service with regular power connected through header J2.
The backup battery protects the contents of the SRAM and keeps the real-time clock
running when regular power to the LP3500 is interrupted. If you plan to use the real-time
clock functionality in your application, you will need to set the real-time clock once you
remove the plastic tab. Set the real-time clock using the onscreen prompts in the demon-
stration program. Alternatively, you may set the real-time clock using the
SETRTCKB.C
sample program from the Dynamic C
folder. The
SAMPLES\RTCLOCK
RTC_TEST.C
sample program in the Dynamic C
folder provides additional exam-
SAMPLES\RTCLOCK
ples of how to read and set the real-time clock.
