PowerTap SL 2.4 - Manual (Page 35)

COMPUTER BATTERIES
The PowerTap SL2.4 has batteries in the hub and computer. Computer bat-
teries typically need to be changed every 400 hours of use. The computer
will also say “low bat” when the computer battery needs to be changed. This
message is displayed after a “clr” is performed. To replace computer battery
(Type CR2032), remove the computer from the mount. Remove the battery
cover on the back of the computer (use a cone wrench to remove the bat-
tery cover), exchange the battery, and replace the cover as shown below
(FIGURE 29).
