Remove and clean the power meter and chainrings using a mild soap and water solution.
Check all bolts for correct torque values. The crank arm retention bolt on a DUB crank set should be torqued to 54nm. Crank arm retention bolts on other crank sets should be torqued to 48-54nm. The chainring bolts should be torqued to 10-12nm (steel SRAM bolts), 12-16nm (Shimano bolts), or the manufacturer’s specifications for 3rd party bolts.
Torque the battery compartment bolt (2mm or T10) to 1nm.
Lastly, gently bend up the 6 battery contact points to ensure good contact with the battery.
Install a brand new CR2032 battery.
Pair the power meter to the SRAM AXS App for all DZero power meters or to Qalvin Legacy (windows/Mac) for legacy power meters. Ensure the power meter is on the latest firmware version. If not, perform the update now.
Perform a Zero Offset. This should be done prior to every ride if you are on a firmware version older than version 10.
Firmware 10 introduced MagicZero, enabling your power meter to perform the zero offset while you ride.
You can now get right back to riding!
