REPLACING THE BATTERY
Follow these steps to change-out a Pit MIU’s internal Battery:
1. Unscrew the Hi-Lo fastener holding the Main Housing to the Mounting Adapter.
2. Remove the seal wire or seal clip from the Seal Holes at the bottom of the Main Housing.
3. Punch the Seal Pin out of the Terminal Screw Cover.
4. Remove the Terminal Screw Cover.
5. Remove the wires from the Terminal Screws. (optional)
6. Using a flat-head screwdriver, gently pry open the clip on the bottom of the Main Housing.
When the clip clears the tab on the Mounting Adapter, pull the Main Housing away from the
Mounting Adapter.
7. Remove the Main Housing by lifting and unhinging it from the Mounting Adapter.
8. Remove the Battery from the Main Housing by pressing in on the right end of the Battery until it
releases and comes free from the Main Housing.
9. As close to the Battery as possible, cut the battery connection wires one at a time.
Note:
Cutting the battery connection wires one at a time prevents shorting.
10.Use Skotchloks to splice the wires from the new Battery to the wires that connected to the old
Battery.
Note:
Insure the Pit MIU’s black wire is connected to ground (-) and the red wire is connected to
the positive (+) wires of the new battery.
