Like any electronic device, Mpower pod(s) should be treated with care. The suggestions below will help you fulfill guarantee obligations and enjoy this product for many years to come.

Don't charge the pod(s) when its USB port is wet. Let the USB port dry up by before charging. This way you ensure smooth charging.

Wipe off any moisture before storing the pod(s). Don't store in non-breathable material or in a damp environment like e.g. plastic bag or damp gym bag.

Keep your pod(s) clean. We recommend that you clean and dry your Mpower pod regularly, particularly in areas in contact with the skin. Wipe it dry with a soft cloth or paper towel when needed. Use a clean, dry or damp cloth or paper towel as needed for cleaning. If using Mpower with multiple users, the hygiene can be ensured by wiping with a cloth moistened with disinfection liquid. Never pour any liquid material directly on the pods but always use soft cloth or paper. Do not wash the pods under a faucet. Rough handling may damage the electrodes.

Keep your straps clean. Rinse the strap under running water (detach pod from strap before doing this!) after every use and hang to try. Clean the strap gently with mild soap and water solution when needed. Do not use moisturizing soaps as they can leave residue on the strap. Do not soak, iron, dry clean or bleach the strap.

When you connect your Mpower pod to a computer or a charger, check that there is no moisture, hair, dust or dirt on the pod's micro-USB connector. Gently wipe off any dirt or moisture. Don't use any sharp tools for cleaning to avoid scratching.

Use the pods within specified operating temperature range. Protect the pod(s) from excess weather conditions by covering it under your clothing.

Wearing and caring tips

  • • Clean and dry your Mpower product regularly, particularly in areas in contact with the skin. Use a clean, damp cloth. You may also use disinfecting alcohol on a damp cloth. Do not use abrasive or corrosive cleaners for cleaning. Do not wash the product under a faucet or in any other way.

  • • Use skin care products sparingly on the areas of the skin covered by your Mpower product.

  • • Do not open the enclosure or disassemble your Mpower product.

  • • Substances in this product and its battery may harm the environment or cause injury if handled and disposed of improperly.

  • • Do not place your Mpower product in a dishwasher, washing machine, or dryer.

  • • Do not expose your Mpower product to extremely high or low temperatures.

  • • Do not use your Mpower product in a sauna or steam room.

  • • Do not leave your Mpower product in direct sunlight for an extended period of time.

  • • Do not dispose of your Mpower product in a fire. The battery could explode.

  • • Do not wear your Mpower product while charging it.

  • • Do not charge your Mpower product while it is wet.

  • • Remove your Mpower product if it feels warm or hot.


Single user

sEMG-signal is by its nature characteristic for an individual person and individual muscle depending on the muscle size and how much the muscle has been exercised. The sEMG-signals measured from different individuals and the calculated activation levels may vary substantially between individuals. Mpower is designed to measure and process the personal, muscle specific sEMG-signal by calculating, comparing and storing individual muscle activation levels obtained from the signal. With subsequent measurements Mpower forms the personal muscle specific training, activation and development history.

Multiple users

Mpower can be used with multiple users, which makes it convenient for operating with customers and team members. This is done by establishing a personal account for each user for storing the personal training and measurement data.

Pod placement

Pod is placed on the skin on top of the measured muscle with a strap or an adhesive tape. The recommended place for the pod is in the middle of the measured muscle as this ensures that the captured sEMG-signal is as muscle specific as possible. The best comparable results are achieved when the pod is attached to the same place on the muscle for each measurement. For large muscles it may be difficult place the pods exactly to the same spot for each subsequent measurement, but small location variations (10-20 mm depending on the muscle size) have been noticed to cause in practice insignificant variation to the measured signal levels. The correct pod placement on the muscle can be determined by contracting the muscle and sensing its approximate middle point.

You may also use Mpower to measure the activation of different ends of large muscles. For this purpose place the pod to the desired end of the muscle and use the same pod location with the subsequent measurements. This way you may better discover exercises and techniques, which direct the activation to a desired end of a large muscle.

IMPORTANT: Always activate the Mpower measurement functionality only after the pods are placed on muscles. Never move or adjust the pods when the measurement is active as this may cause signal spikes, which appear as false muscle specific maximum activation levels and distort the subsequent measurement results. Nevertheless, if this happens accidentally, use the “Settings” menu to remove the false calibration values caused by undesired signal spikes.

Impact of fat tissue

sEMG-signal is attenuated by the fat tissue under the skin. If fat tissue is thick enough, it may attenuate the sEMG-signal so much that Mpower cannot detect it. In such case it is recommended to use dietary and training means to lower the thickness of the fat tissue and use Mpower to monitor when the sEMG-signal can be detected


Mpower is splash proof, but it cannot be immersed into a fluid. Therefore, it is not suited for e.g. swimming. Heavy and continuous sweating during long-lasting training may impair Mpower capability to detect the sEMG-signal. This may show as a sudden drop in activation levels. Should this happen it is recommended to stop the measurement, remove the pod from the muscle and wipe away the excess sweat off the pod and the muscle. After that pod is re-attached to the dry muscle and the measurement can be continued.

Battery charging

The Mpower pod has an internal, rechargeable battery. Rechargeable batteries have a limited number of charge cycles. The number of charge cycles also varies according to use and operating conditions. Do not charge the battery in temperatures under 0°C or over +40°C or when the USB port is wet.
