Morpheus doesn't see the M3 when I try to connect to it

If you're not seeing the M3 show up in your Bluetooth devices list when trying to connect to it, then it's generally caused by one of three things:

  • You don't have the M3 in the correct place across your chest and/or you don't have good skin contact
  • You have paired the M3 directly to the phone or to another app
  • The battery needs to be replaced

Start by making sure you are wearing the band in the correct placement across your chest and you have good skin contact by ensuring the electrodes are moist. You can also unsnap the sensor and then snap it back in.

Open Bluetooth settings in your phone or device and make sure it's not paired directly to the phone. Also, check to see if you have any other apps open that might have automatically paired to it.

If you still aren't able to detect the M3, open the battery compartment and make sure the battery is seated properly.  If this does not fix anything, then follow the instructions below to change the M3 battery.


Replacing the battery

The M3 uses a standard CR2032 3V battery that is commonly used in watches. You can find a replacement battery at almost any drug store.

To replace the battery, use a coin to twist the cover counter clockwise until it opens. You can then remove the old battery and inset the new one.

Make sure that the battery is inserted with the + side facing up.

You can also adjust the small metal clip underneath the battery by gently pulling up on it before inserting the battery to ensure it fits snugly in the case.

My heart rates seem inaccurate

Inaccurate heart rates are almost always caused by poor skin contact and placement, or wearing the sensor upside down.  Follow the steps listed above to impact skin contact and make sure that the Morpheus logo is facing right side up so that someone facing you could read it.

Inaccurate heart rate can also be caused by a battery that is too low power or a battery that has become dislodged inside of the transmitter casing.

We have 3 recommendations for improving connectivity, HR accuracy, and battery life.

1) Open the battery compartment by using a coin.  Cut a small piece of a paper towel or napkin (or something similar) and fold it multiple times so that it fits in the circular compartment.  Place it on top of the battery and then place the cover on and push down hard and then twist to close the cover.  That will hold the battery down and in place and in contact with all of the side metal brackets, which is needed tor accurate readings.  Without doing that it is possible that over time, the battery can come loose inside the compartment, such as the picture below.  This can happen even with the cover screwed on.  It's a very common issue with chest strap transmitters.

2) When you are done using your M3, fully disconnect the transmitter from the strap and wipe off the two metal pegs on the back of the transmitter with a towel and then rinse the strap in under warm water and then wipe it dry (once over) with a towel and then let it hang dry.
Keeping the transmitter connected to the strap all the time does two things that you don't want - it drains the battery faster and it can corrode the metal pins over time with contact from salt from sweat, such as the picture shown below.

3) From removing the M3 transmitter over and over again, the horizontal bars that hold the M3 transmitter on the strap could be bent which would not allow the M3 to be fully in contact with the inside of this port.   Picture below.


I'm losing connection during my workout

The most likely causes for the M3 to lose connection to your phone or other device are that either the strap is losing skin contact, or your device is out of range.

Tighten the strap to ensure that it will not move around during your workout.  Add water or electrode gel to the strap to improve connectivity.

Make sure that your phone or other Bluetooth device is within 30ft of the M3.  It can begin to lose connection if this range is exceeded, or if there are objects in the way of the signal.


I'm having trouble syncing the M3 to Morpheus after a workout

Please note that this only applies to M3 devices purchased before October 2019.

If Morpheus shows no saved data when trying to Sync to the M3 after a workout, first make sure that the M3 was NOT connected to any Bluetooth devices during the workout. 

If it is connected to anything via Bluetooth, it will not record.

To make sure that the M3 is working and recording data, it's recommended to check your heart rate using a piece of compatible cardio equipment or ANT+ device that displays heart rate. You should see the M3 sending heart rate data. This indicates it's on and recording data properly.

You can also confirm the M3 is working by connecting to Morpheus as long as you disconnect it by turning Bluetooth off in your phone before you want to start recording. If you do not disconnect it from Morpheus, it will not record your workout data.
