Steps
1. If you are not already grounded, properly ground yourself.
2. Open the air duct:
a. Press the locking tabs on the sides of the air duct in toward the middle of the controller module.
b. Slide the air duct toward the back of the controller module, and then rotate it upward to its completely
open position.
3. Locate, remove, and then replace the RTC battery:
a. Using the FRU map, locate the RTC battery on the controller module.
b. Gently push the battery away from the holder, rotate it away from the holder, and then lift it out of the
holder.
Note the polarity of the battery as you remove it from the holder. The battery is marked
with a plus sign and must be positioned in the holder correctly. A plus sign near the
holder tells you how the battery should be positioned.
