3.3 Lithium battery maintenance
The SDR2-CF's real-time clock uses a small lithium battery to maintain time
when external power is unavailable. The life of this battery should exceed 5
years.
If you find your SDR2-CF is not keeping time correctly or that the time is
displayed with a question mark (
?
) after it when you power up, you may
need to replace the battery. If necessary, replace the battery with a
Panasonic CR2032, or equivalent, making sure the positive (+) face is in
contact with the battery clip. After replacing the battery be sure to reset the
SDR2-CF’s time and date.
