Comosystems CMO MP24 Easycall

Use a CMO when exposed to EMFs

CMO stands for Magnetic Compensation Oscillator. A CMO reacts to electromagnetic fields (EMFs). A CMO itself produces a weak electromagnetic field when exposed to artificial EMFs.

Comosystems CMO technology

Comosystems makes CMOs by dissolving ions in water. This solution is exposed to electromagnetic fields and has a 'memory' of them. This ion solution is protected by a sturdy aluminium housing.

Passive protection

The CMO creates an electromagnetic field by exposure to an electromagnetic field. This is a property of the ion solution and does not require a source of energy. The CMO will also not 'run out'.

No interference with electronics

The CMO signal is very weak compared to other artificial electromagnetic fields emitted by electronics. So the CMO will not disturb electrical devices.

MP24 Easycall: CMO for smartphones and small electronic devices

The MP24 Easycall is a very small CMO for mobile phones, smartphones, tablets and other small electronic devices. Attach to the device or case with the included sticker.

  • Shape: coin with sticker
  • Weight: 2,5 g
  • Thickness: 4,3 mm
  • Diameter: 25 mm
  • Effective area: 1 person

Types of EMFs to which the MP24 Easycall reacts

The MP24 Easycall compensates for the effects of:

  • GSM 900 / GSM1800
  • EDGE
  • GPRS
  • UMTS / 3G / 3G+ / 4G / 5G (when available)
  • Bluetooth
  • Wi-Fi
  • CDMA
  • iPhone / iPad
  • GPS
  • baby phones
  • DECT phones combined

Other CMOs for personal or specific purposes

Each CMO compensates for specific types of EMFs and has its own area of operation. Combine personal and specific CMOs for the most complete compensation.



Stick the MP24 Easycall on the electronic device that gives off EMFs for which you want to compensate.

Do not expose the CMO to temperatures above 60°C or prolonged direct sunlight. This may interfere with the ion solution and reduce the CMO's effectiveness.


The CMO is effective for at least 2 years. The manufacturer expects the CMO to remain effective for a long time thereafter, but has not yet been able to confirm this.

Made in France.
