Follow these steps to change-out the pit R450 MIU's internal battery:

Removing the Battery

1 Slowly remove the pit lid.
Because the MIU is connected to both the antenna
in the pit lid and the meter in the pit base, take care
not to strain the cable when removing the lid.
2 Remove the transmitter cover by removing the two Phillips head
crews located inside the back cavity of the main housing.
(See Figure 9.)
3 Lift the transmitter cover from the MIU.
4 Remove the battery casing from the main housing by inserting a flat-
head screwdriver and dislodging the battery from the battery com-
partment. (See Figure 10.)
When removing the battery, it may be helpful to press on the connected
end while prying the other end.
