This manual provides instructions for setting up, pairing, charging, and using the Polar OH1 optical heart rate sensor for training.
The Polar OH1 is a compact optical heart rate sensor designed to measure heart rate from the forearm, upper arm, or temple during swimming. It serves as an alternative to chest straps and wrist-based devices, transmitting real-time data via Bluetooth and ANT+ technology to compatible watches, smartphones, and fitness applications.
The device features a built-in memory capable of storing up to 200 hours of training sessions, allowing users to start workouts independently without a connected watch. Users can sync their data using the PolarFlow app or FlowSync software on a computer for detailed analysis and community sharing. This manual is written in Chinese.
