U SING THE OMP-MODL 6-9
The MC-XX memory cards utilize an internal lithium cell (Panasonic BR-2325, 3V or
equivalent) for power when not installed in the OMP-MODL or the PD-1 drive at the
PC location. This lithium cell should be replaced yearly for maximum data integrity.
Data in memory will be maintained for up to 2 hours with the battery removed from
the compartment, however it is highly recommended that any valuable data in the
card be downloaded before replacing the battery.
To replace the cell:
1. Locate a clean area to work.
2. Visually locate the battery access door and lock located on the
end of the memory card opposite the connector end.
1. Using a paper clip or other small probe, slide the Lock pin away
from the embossed LOCK mark.
2. Swing open and remove the battery compartment door . The
lithium cell can then be removed.
3. Slide the new cell into the compartment insuring the positive (+)
side of the cell is toward the top of the card.
