COMPUTER BATTERIES
The PowerTap SL has batteries in the hub and computer. Computer batteries
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 battery
cover), exchange the battery, and replace the cover as shown below (FIGURE
29).
