4. Setup
Battery Installation:
- Locate the battery compartment cover on the back of the Irfora FY8817 device.
- Slide or unclip the cover to open the compartment.
- Insert one 9V battery (not included), ensuring the positive (+) and negative (-) terminals align correctly with the markings inside the compartment.
- Close the battery compartment cover securely until it clicks into place.
The device is now ready for operation.
5. Operating Instructions
Powering On/Off:
- To turn the device ON, press the red power button located on the front of the meter. The LEDs will briefly illuminate.
- To turn the device OFF, press the red power button again.
Taking Measurements:
- With the device powered on, hold it in the area you wish to test for electromagnetic fields.
- Move the device slowly around the area or object.
- Observe the 5 LED lights on the display. The illuminated LEDs indicate the strength of the detected electromagnetic field.
The Irfora FY8817 is suitable for detecting radiation from various household and office appliances.

6. Understanding Readings
The Irfora FY8817 uses a 5-LED display to visually represent the intensity of electromagnetic radiation. Each LED color corresponds to a specific range of milliGauss (mG) and indicates a relative risk level.
Figure 6.1: Detailed explanation of the LED indicators and their corresponding EMF levels and risk categories.
Radiation Display Metrics:
- Green (0-1.5mG): Normal level.
- Blue (1.5mG-2.5mG): Low risk level.
- Yellow (2.5mG-10mG): Medium risk level.
- Orange (10-20mG): High risk level.
- Red (20+mG): Ultra-high risk level.
Note: Scientists generally agree that long-term exposure to electromagnetic radiation below 2 mG is considered the safest level.

7. Maintenance
Cleaning:
- Wipe the exterior of the device with a soft, dry cloth.
- Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the casing or internal components.
Storage:
- Store the Irfora FY8817 in a cool, dry place, away from direct sunlight and extreme temperatures.
- If the device will not be used for an extended period, remove the 9V battery to prevent leakage and potential damage.
Battery Replacement:
Replace the 9V battery when the device no longer powers on, the LEDs appear dim, or readings become inconsistent. Refer to the 'Battery Installation' section for instructions.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is dead or incorrectly installed. | Check battery installation. Replace with a fresh 9V battery. |
| LEDs are dim or flicker. | Low battery power. | Replace the 9V battery. |
| Inconsistent or unexpected readings. | Interference from other electronic devices; device not held steadily. | Move to a different location away from strong electronic sources and retest. Hold the device steadily during measurement. |
| No LED indication when detecting. | Device is off; no significant EMF detected; battery issue. | Ensure the device is powered on. Test in an area known to have EMF (e.g., near a running microwave). Check/replace battery. |
