4. Setup
4.1 Charging the Device
The Neoteck RD670 comes with a built-in 1200mAh rechargeable battery. Before first use, or when the battery indicator shows low power, charge the device using the provided Type-C USB cable.
- Connect the Type-C end of the charging cable to the charging port on the side of the detector.
- Connect the USB-A end of the cable to a standard USB power adapter (not included) or a computer's USB port.
- The battery indicator on the screen will show charging status.

4.2 Powering On/Off
- To power on, press and hold the Power button (
) until the screen illuminates. - To power off, press and hold the Power button again until the screen turns off.
5. Operating Instructions
5.1 Basic Measurement
Upon powering on, the device will immediately begin measuring Electric Field (EF), Magnetic Field (MF), and Radio Frequency (RF) radiation. Readings for all three fields are displayed simultaneously on the backlit LCD screen.

5.2 Understanding the Display
The screen is divided into three main sections for EF, MF, and RF readings. Units are displayed next to the numerical values.
- EF (Electric Field): Measured in V/m (Volts per meter). Range: 1-1999 V/m.
- MF (Magnetic Field): Measured in mG (milligauss) or µT (microtesla). Range: 0.1-999.9 mG / 0.01-99.99 µT.
- RF (Radio Frequency): Measured in mW/m² (milliwatts per square meter) or µW/cm² (microwatts per square centimeter). Range: 0.1-999.9 mW/m² / 0.01-99.99 µW/cm².
5.3 Unit Switching (MF and RF)
- To switch MF units between mG and µT, press the mG/µT button.
- To switch RF units between mW/m² and µW/cm², press the mW/m²/µW/cm² button.
5.4 3-Axis Magnetic Field Detection
The device can detect magnetic fields along the X, Y, and Z axes, allowing for identification of the magnetic field's direction. The display will show the current axis being measured or a combined reading.
- X-axis: Represents the width direction of the detector.
- Y-axis: Corresponds to the height direction of the detector.
- Z-axis: Perpendicular to the detector's screen.

5.5 Visual and Audio Alarm
The detector provides immediate feedback on radiation levels through a tri-color LED and an audible buzzer.
- Green LED: Low radiation levels.
- Blue LED: Medium radiation levels.
- Red LED & Rapid Beeps: High radiation levels, exceeding safety thresholds.
Alarm Thresholds:
- EF: 250 V/m
- MF: 5 µT / 50 mG
- RF: 50 mW/m² / 5 µW/cm²

To mute the audio alarm, press the Mute button (
).
5.6 Intelligent RF Recognition
The detector can identify and display specific types of RF signals:
- When a Wi-Fi transmission source is detected, the screen shows "WIFI/PHONE".
- When a microwave source is detected, it displays "MICROWAVE*".
- For mixed signals, it shows "MIXED".

5.7 Data Hold Function
To freeze the current readings on the screen, press the HOLD button (
). Press it again to resume live measurement.
5.8 Auto Power-Off (APO)
The device has a 15-minute auto-shutdown function to save battery. To disable this feature for continuous measurement, press and hold the APO button (
) until the APO indicator on the screen disappears. Press and hold again to re-enable it.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
- Storage: Store the detector in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided storage bag for protection.
- Battery Care: Recharge the battery regularly, even if the device is not in frequent use, to maintain battery health. Avoid fully discharging the battery for extended periods.
- Avoid Impact: Protect the device from drops and strong impacts, which can damage internal components.
