Wireless PowerTap Ant+ Updater Instructions:
1. Unscrew the plastic battery cover using the cap tool included with the PowerTap hub.There are O-ring seals that can
cause the cover to resist the start of motion.Turn the cap counter-clockwise to unscrew.
2. Remove the battery assembly from the hub by grabbing the tabs on the ends or the blue wire and pulling away from
the hub. A gentle side to side rocking motion may assist the removal.
3. Check that the electrical connector tab on the inside of the hub is perpendicular to the bottom of the battery pocket. If
the tab is bent, gently press it back into place with a blunt tool.
4. Insert the updater onto the electrical connector tab. Ensure the updater is fully seated into the battery pocket.
