If you ordered a left side or dual PRECISION 3 or PRECISION 3+ powermeter, and are in the United States, starting in April 2024 your powermeter may have come with a safety clip protecting the battery cap. This safety clip is a solution to ensure compliance with the recently introduced Reece's Law in the United States.
Due to the recently introduced Reese’s Law (P.L. 117-171) in the United States, we have had to modify the PRECISION 3+ powermeter to ensure compliancy with the new law. The US Consumer Product Safety Commission introduced this new law to increase child safety around products using coin cell or button batteries, which our power meters operate on.
Please see the below instructions for removing and reinstalling the battery cap with the safety clip.
