Morpheus M7 User Guide

The M7 features the most accurate ECG and sensor in the industry packed into a slim and lightweight design.

It includes 10 hours of built-in memory and up to 200 hours of battery life on a single charge.  The M7 is designed to work with the Morpheus Training system, but it can also be used with:

  • ALL Bluetooth devices and apps

  • ANT+ devices made by Garmin, Suunto, Samsung and more

  • Cardio equipment that accepts ANT+ or Bluetooth heart rate transmission (such as Octane, Woodway, Technogym, and more)

Follow the steps below to start using the M7 to get the most out of your training.  You can also contact support with any questions not covered in the guide by clicking here to send an email to us.

Getting Started with the M7

1. Before you use the M7 for the first time, it may need to be charged before it can be turned on.

2. Please use a standard power adapter to charge the M7

3. The LED shows red when charging, and green when fully charged.

Connect the M7 to the Morpheus Training App

**Note:  Before the M7 can store workout data in its memory, the time must be set by connecting it to the Morpheus Training app.

Until you do this, it will not save workout data.

DO NOT connect the M7 directly to your phone through Bluetooth settings.

1. Put the M7 on to activate the heart rate sensor.

2. Open the Morpheus training app.

3. Press MENU and then SYNC in the Morpheus to connect to the M7 and set its internal clock.

4. Press the blue CONNECT HRM button at the bottom.  You will see a list of any nearby Bluetooth devices.  Choose your M7.  The number in the app will match the number on the back of your M7 transmitter.  Check the box next to your M7 and then press OK.

How to Wear the M7

Making sure that you're wearing the M7 correctly is the most important step to getting consistent and accurate data.  There are three simple keys to wearing the M7 properly: placement, sensor orientation, and skin contact.

Proper placement:

The M7 should be placed directly underneath the pectoral muscles with the sensor over the bottom of the sternum as seen below.

We recommend to put the chest strap on by itself first, then put water or electrode gel on it, and then finally snap the sensor into place before each workout.

Below represents how the M7 should be positioned for men (left) and women (right).  Note that it is also acceptable for women to slide the M7 strap and transmitter under the bottom of a bra.

Note:  Some people may benefit from shifting the transmitter slightly to the left instead of having it centered.  This may place the electrode area of the strap closer to the heart.

It's also possible to place the sensor on your back to the left of your spine.  Just flip the transmitter upside down and it should work just as well as if on your front side.

Important: You will need to turn the M7 on before you can connect it to the Morpheus app. To do this, put the chest strap on as indicated below.

Best steps for putting on the M7:

  1. To get the most accurate heart rate reading, the M7 needs to have good skin contact.  Put the chest strap on your body correctly and tight enough so it doesn't slide down.  It is adjustable to get it just right for you.
  2. Put a fair amount water and/or electrode gel on the skin side of the strap on the rubber sections to the left and right of the middle.  If you do this after you are already wearing the strap then it will be less likely to rub off and will also get on your skin where the strap touches.   Electrode gel will provide the best contact possible, but water works well for most people.
  3. Finally, fully attach the transmitter to the strap by snapping it onto both ports.  You will hear a single audible beep and the LED light will turn on and blink when it's been activated.  It will blink a few times in a white color while searching for HR and then it will blink blue for 10 seconds after it has found solid HR signal.  After that the LED will shut off, but the device remains powered on and active

Sensor Orientation:

Important: In order to read accurately, the heart rate sensor must be snapped into the chest strap so that the Morpheus logo is right side up and could be read by someone facing you.  This means when you snap the sensor into the chest strap, the Left snap should be on the left side of your body and the Right snap should be on the right.  The back side of the sensor also has L and R next to the pins.

**Please note:  all M7s are shipped with a standard size (M-XXL) strap.  Smaller straps are available if you find that you have adjusted the included strap to its smallest size and it's still too loose.  Please reach out to for more info.

Note: When you are not wearing the M7, always fully unsnap the sensor from the chest strap.  Wipe sweat off the back of it to prevent the pins from becoming corroded.  Store it in a location so that the pins on the back of the sensor are not in contact with anything conductive.  It will turn on automatically when you snap it back in and put it on prior to a workout.

If you want an extra strap or a replacement strap you can purchase directly at one of the links below.  Some people choose to have one dedicated to the morning HRV test and they leave it at home.  And the other is used for training.  Other people just rotate through a couple of straps randomly.  An extra strap certainly is not required but is an option.

M7 LED Colors

Once the M7 is worn correctly, the LED will begin flashing white to indicate that it is searching for heart rate.

When it has found your heart rate, it will flash blue for 10 seconds. This lets you know the M7 is working correctly and recording your heart rate.

When you take the M7 off or it's unable to monitor heart rate, it will beep three times to let you know it is no longer receiving or recording heart rate.


The battery life of the M7 is up to 200 hours of activity from full charge to completely drained.  This means you do not need to charge it very often.

Connecting the M7 to your devices


To connect to a phone or tablet, DO NOT pair the M7 to the phone/tablet itself through Bluetooth settings.  Instead, make sure to pair directly to the app that you're trying to connect to.

The M7 connects via Bluetooth using the standard Bluetooth protocols.  You need to first put the chest strap on before connecting to a device or app.

When connecting via Bluetooth, note that the M7 device name will show up including the unique ID number that can be found on the back of the sensor to avoid confusion with other devices that may be in the area.

If you're using the Morpheus Recovery app, you will connect in the “TRAIN” screen prior to your workout.


Many devices like Garmin, Suunto and more use the ANT+ protocol in order to transmit heart rate.  To connect your M7 to an ANT+ compatible device, follow the instructions of your device to find and pair to the M7.

The M7 is capable of connecting via Bluetooth and ANT+ at the same time if necessary.

Using the M7 without the Morpheus app - Syncing Workouts

If the type of training you're doing makes it difficult or impractical to use the Morpheus app, you can use the M7's onboard memory to train and record your workout to sync to Morpheus after it's done.

The M7 can record up to 10 hours of workout data that can be imported directly into the Morpheus app using the SYNC feature.  This is meant only for times when you are training WITHOUT being connected to the Morpheus app.

You can choose to use the M7 by itself, or you can also connect it any heart rate watch or device that is compatible with Bluetooth or ANT (see the section below for details).

The M7 starts recording the moment that you put it on and it starts detecting your heart rate.  It stops recording when you take off the strap and/or remove the transmitter from the strap and it beeps 3 times to power off.  All workouts that you do with the M7 are automatically recorded in this manner.

This makes it quick and easy to SYNC your workouts into the app so Morpheus can track them.

IMPORTANT: To sync a saved workout from the M7 to the Morpheus app, you must first be wearing your M7 so that it is powered on.

Quick tip: you can also place your thumbs directly on the two silver nodes on the back of the sensor to turn it on as well.

Once the M7 is turned on, open the Morpheus app and press SYNC from the main navigation menu and then connect the app to the M7.  This will trigger the syncing process during which the M7 is sending workout data to your phone.  Do not close your app or navigate away from this screen during this syncing process.

This will bring up a list of saved workouts that are stored on the M7.

**Please note:  The M7 records ALL workouts that are at least 10 minutes in length, regardless of whether you are using the Morpheus app in real time or not.  If it's been a while since you have done this sync process and/or you have long workouts or several workouts on your M7, this sync process could take about a minute or so.

Choose any of the saved workouts that you'd like to import by clicking on the box to the left of the workout(s).

Any workout that you do not select will automatically be deleted from the list.  So be sure that you choose every workout that you need.

Since the M7 records all workouts, there may be workouts in the list that you completed while connected to the Morpheus app in real time.  No need to select and import those because they have already been fully recorded and saved.

But if you do select one that has already been recorded live in the app, the synced one will override it and there will not be a duplicate workout.  So there's no harm in doing so, just no reason to do so if you can avoid it.

Press NEXT when ready.

Once you've done this, you will see the workout details appear on the screen.

First, select a workout category (cardio, mixed, or strength).

Then, if needed you can trim any time from the beginning of the workout or the end of the workout using the blue slider bar.  This is not required but is useful in situations where you may have "garbage time" between putting on your M7 and actually starting workout.  Or maybe you completed your workout but you don't take off the M7 right away.  This slider can help you keep only the data that was a part of your actual workout.

Then use the sliders to rate how hard the workout was (RPE) along with your performance.  And enter any workout notes if you want to.  You can also choose to enter notes later from the workout results screen.

When you are finished, tap SUBMIT to complete the process.

DO NOT close the app or navigate away from the screen during the import.

Once the process is completed, you will see a notification that the import process has been completed.  You can choose to view the workout results by tapping YES.  Or you can choose SKIP IT and you'll be redirected to the home screen of the app.

Lastly, when you look at your workout history in the app either on the home screen or by tapping the calendar icon at the top right of any workout results screen, you will notice that all SYNCED workouts have an asterisk * next to the date.  And all workouts that we completed LIVE with the app do not have an asterisk *
