F45 LionHeart HRM Armband User Manual — Model HW852 F45, Version v1.0
Thank you for purchasing an official F45 LionHeart Heart Rate Monitor (HRM). Your LionHeart HRM connects you to our in-studio gamification platform, relaying real-time heart rate information to the in-studio F45 LionHeart TV leaderboards.
Before wearing your device for the first time, you must:
- Register it via the F45 Training app from the iOS or Android app store.
- Remove the plastic covering on the backside of the device protecting the sensor. This will avoid inaccurate heart rate readings.
Wearing Your Armband
The suggested place to wear the armband is on the upper portion of the forearm. The sensor should be on the inside or top of the forearm. It should be worn snug enough not to move on your arm, but NOT so tight that it restricts arm blood circulation.
Function and Operation
Turning the device on
- Press the device button once.
- The LED light will pulse blue when the heart rate is detected.
Turning the device off
- Hold the device button for a few seconds.
- The LED light will flash red, vibrate, and then turn off.
Heart Rate Zones & Alerts
The default Max Heart Rate (MHR) is set to 180. The LED color indicates your current heart rate zone:
| Zone | Color | Range (Default) |
|---|---|---|
| Zone 1 | Pale Blue | Below 65% MHR |
| Zone 2 | Blue | 65% ~ 75% MHR |
| Zone 3 | Purple | 75% ~ 85% MHR |
| Zone 4 | Pink-Red | 85% ~ 95% MHR |
| Zone 5 | Red | Above 95% MHR |
Heart rate alert: If the heart rate exceeds the maximum value, the sensor will vibrate three (3) times consecutively.
