Replacing the MMC Battery
Follow the procedure below to replace the MMC battery when the “P” light is flashing.
1.
After DC power has been applied to the MMC for at least five minutes, turn off
power. This ensures that the contents of memory will not be lost while the battery
is removed. Disconnect the input power connector from the MMC.
2.
Remove the MMC (including any optional modules) from the cabinet.
3.
Use a static-free work surface if possible. Ground yourself using a properly
grounded wrist strap before you open the case. These are standard precautions
before handling any electronics component.
4.
Lay the MMC system on the work surface. If there are no optional modules
attached, remove the cover by removing the five screws, two on top, two on the
bottom, and one on the right side of the MMC.
If there are one or more optional modules attached, remove the four screws that
attach the first optional module and remove the MMC from the optional modules.
