It is recommended that the memory card battery be changed every
2 years. The battery is a lithium commercial CMOS type battery,
part number CR 2016. The minimum lifetime of the battery (under
ordinary conditions) is more than 2 years.
The date that the memory card battery was installed is either
engraved on the side of the memory card or written on a label on the
memory card.
If the memory card does not have a label with the date that the
battery was installed, use the date code engraved on the side of the
memory card. The date code engraved on the memory card consists
of numbers and letters engraved in the black plastic on the side of
the memory card. Refer to Figure 7-1. The rst number indicates
the year, the following two characters indicate the month, and the
following number indicates the week in the month that the memory
card battery was installed. For example, 8OC3 indicates the battery
was installed in the third week in October in 1988.
