Install a new CR2032 coin cell battery into the battery compartment,
positive side facing outward.
⚠ WARNING
Keep the battery out of reach of children. Do not put the battery in
your mouth. If ingested, seek medical attention immediately. Do not
disassemble, damage, or puncture the battery. Consult the battery
manufacturer for safe handling instructions.
Install the battery compartment lid until it is handtight. Watch for the
LED to blink on; green for DZero™ power meters, and red for Legacy

If the LED blinks on, connect the power meter to the appropriate Qalvin™ version and update the power meter firmware, if needed.

If the LED does not blink on and the power meter will not pair to a head unit or Qalvin:
DZero™ Power Meter: Contact Quarq® customer support or your Quarq® dealer.
Legacy Power Meter: Perform the Spider Inspection steps in the following section.
This completes the troubleshooting for the Power Meter Reboot service.
