Although the M5 was primarily designed to measure HRV, it can also be used with the M7 during your workouts.
This gives you the ability to see your live heart rate and zones even when you’re training without the Morpheus mobile app. That means it’s easy and convenient to use Morpheus during any type of training.
Note: While optical heart rate monitor technology typically provides the best estimate of a user's heart rate, there are inherent limitations with the technology that may cause some of the heart rate readings to be inaccurate under certain circumstances, including the user's physical characteristics, fit of the device, and type and intensity of activity.

Using the M5 with the M7
To pair the M7 to the M5, put the M5 on and navigate to TRAIN by tapping on the screen and then pressing the side button to choose this mode.
Note: because the M5 is receiving heart rate from the M7, you can wear it wherever you feel is the most comfortable. You don't even need to wear the M5 in this case, you could have it next to you or in your pocket, for example.
Once you’ve selected TRAIN, the M5 will give you the option to choose between using its own sensors (M5) or an ANT+ Device (M7 or other compatible HRM).
Tap the screen to select “ANT+ Device” and then press the side button to confirm.
When the M5 finds the M7 (or other compatible HRM), it will return an ID# highlighted in white on the screen. The M7 ID number is located on the back of the transmitter that snaps onto the strap.
Press the side button to confirm.
After you have confirmed your M7, you will see your heart rate displayed on the M5. This means you’re ready to train!
Note that when you’re training with the M5 and M7, both devices will record your workout in their memory. To avoid duplicating workouts in the Morpheus app, you should only sync the workout from the M7 directly.
Use the touchscreen to toggle to Cardio, Mixed, or Strength.
Press the side button to confirm your choice.
If your workout will primarily consist of cardiovascular (cardio) type exercises, choose CARDIO. If your workout will only include strength training, select STRENGTH. For any workout that will include both types of training, select MIXED.
Note: Personalized heart rate zones (colors) will only be displayed for CARDIO and MIXED workouts. Heart rate training is not necessary or beneficial when the workout does not include any cardio type exercises.
When you are in one of the 3 heart rate zones you will see the live heart rate number change colors to reflect the zone you are in. In the upper left corner you will see the total time you have been in that zone. In the upper right corner you will see your connection type (ANT or BLE) and the signal strength. You will also see the battery life indicator icon for your M5.
When you are ready to end your workout, press the side button on the M5 to see the screen shown below...this is a "pause" screen. To end the workout, press the side button again while "End Workout" is highlighted. Or to return to the workout, tap the M5 screen to highlight "Return" and then press the side button to confirm.
After confirming you want to end the workout, you will see the total training time. You can use the touchscreen to toggle through the zones to see the amount of time spent in each of the 3 zones.
Press the button to return to the digital clock screen.
The M5 screen will eventually turn off on it's own.
FAQ & Troubleshooting
Q: Can I train with the M5 without connecting it to the M7?
Yes, the M5 can be used by itself during a workout, but in order to ensure the highest accuracy, it should only be used with low-to-moderate intensity workouts.
This is because all optical sensors, like the ones used in the M5 and all wrist and arm-based devices, become less accurate at higher heart rates and movement speeds.
For any type of training that includes high intensities and rapid movements, it’s recommended to use the M7 together with the M5 or by itself.
Q: Can I connect other chest straps to the M5 to workout?
Yes, the M5 can connect to any ANT+ chest strap and display heart rate. Use the same process to pair to a different device.
Because the M5 will record all workouts, you can sync any workout done with other chest straps using the process described in the last lesson.
Q: Why isn’t the M7 ID showing up on the M5?
If you’re not seeing the M7 ID when you search for ANT+ devices, make sure that you’re wearing the M7 so that it’s turned on and reading heart rate.
The M7 will beep three times when it turns on and the LED light will blink blue when it’s reading HR. As long as it’s on and reading heart rate, it will show up in the M5.
