I am having trouble with my new 4iiii power meter. What should I do?

If you are having trouble with your new 4iiii power meter, please try the following steps:

1) Update your cycling computer to the latest firmware.

Connect to the 4iiii app (iOS – 2.4.0; Android – 2.6.0) and ensure you have updated the power meter with the latest firmware (3.2.0). This includes the Chipolo Tracking feature. Ensure that your phone is connected to Wifi.

2) Perform a Factory Reset via the 4iiii App to restore factory calibration values:

  • Connect to your power meter by Adding Device
  • Advance to the Device Settings Page by tapping the power meter field/box
  • Under PRECISION Settings, tap Factory Reset

3) Open your battery cap and gently nudge the two copper battery contacts with your finger to make sure they are well attached. There should be a little one near the edge, and a large rectangular one in the center.

If it looks like the large rectangular one is flat against the bottom, use a jeweller’s screwdriver or similar tool to very gently lift the ends of the prongs 1mm off the bottom of the pod, so that they press against the battery more firmly.

Then, place an upside down (+ terminal down) battery into the pod so that it touches both of the battery contacts for a few seconds before reinstalling the battery in the correct orientation. This will remove any residual charge.

4) Check the battery cap to ensure the metal clip is present:

5) Check locking tabs on body are undamaged:

  • Make sure you are paired to Left ANT+ ID
  • Remove other ANT+ sensors from the cycling computer
