How does the Power HR strap work?  

After installing the app from the app store, restart your phone and enable Bluetooth to avoid connection problems.
Once connected to your device using the app, the Power HR strap (a) automatically detects, measures, and wirelessly 
transmits your heart rate (bpm) and your workout intensity output (Watt) in real time to your device (b). 

When the 2 conductive pads (5) are properly moisturized and positioned on your chest, the Power HR sensor will detect 
your ECG (electrical signal) and calculate your current heart rate frequency (beats per minute).

The Power HR sensor calculates your power output using advanced algorithms based on your real time heart rate.

implanted electronic device, consult your physician before using a heart rate monitor. The Power HR strap is intended 
for recreational use only and is not intended for medical purposes. Heart rate and other readings could be influenced 
by interference from external sources.

If you use the Power HR strap with navigation software, always stay aware of your surroundings and do not fixate on 
the screen. Moreover, set destinations and other user inputs prior to your departure to ensure your attention stays on 
task instead of on the device.

The Power HR strap may work with other apps but it may connect differently than the iMaze app does.  Please see the 
other app's website for detailed instructions on installation and use. You must pair and connect the Power HR strap 
separately with each app you use.  You can’t connect in one app and have it recognized in others.
