Safe & Sound Pro II RF Detector User Manual
Model: Pro II | Brand: Safe Living Technologies
1. Introduction
The Safe & Sound Pro II RF Detector is an advanced instrument designed for measuring electromagnetic radiation (EMF) and high-frequency radiation. It utilizes state-of-the-art measurement technology to detect EMF emissions across a sensitive range, starting from 0.001 µW/m² and covering frequencies up to 8 GHz. This device is suitable for assessing various sources of radio frequencies and microwave radiation, including those from televisions, computers, and cellular towers. Its design prioritizes user-friendliness, energy efficiency, and compliance with stringent building biology guidelines for healthy living and working environments.
2. Setup
2.1 Battery Installation
The Safe & Sound Pro II requires 3 AAA alkaline batteries for operation. To install the batteries, locate the battery compartment on the back of the device. Open the compartment cover, insert the batteries according to the polarity indicators, and then securely close the cover. The device is ready for immediate measurements once batteries are installed.

LED indicators for signal strength (Slight, Moderate, High, Extreme) are visible at the top. Controls for audio (On 4x, On, Off) and sensitivity (High, Med, Low) are located below the display, along with a 'Max Reset' button.
3. Operating Instructions
3.1 Powering On/Off
To power on the device, press the designated power button. The high-resolution OLED display will illuminate, showing current readings. To power off, press and hold the power button until the display turns off. The device is designed to be energy-efficient, contributing to longer battery life.
3.2 Display Modes
The device offers flexible display options. Users can select between units of volts per meter (V/m) and microwatts per square meter (µW/m²) for measurement readings. The self-illuminating OLED display ensures clear visibility in various lighting conditions.
3.3 Audio Feedback
The Safe & Sound Pro II includes high-quality, adjustable audio output. This feature, combined with a 3.5 mm headphone jack, allows for more precise identification of RF signal sources through audible cues. The audio can be set to different sensitivity levels (High, Med, Low) or turned off.
3.4 Measurement Interpretation
The device provides real-time readings for Peak, Max, and Average electromagnetic field strengths. Four color-coded LEDs (Slight, Moderate, High, Extreme) offer a quick visual indication of the detected signal strength, helping users understand the level of EMF exposure in their environment.
3.5 Max Reset Function
A 'Max Reset' button is available to clear the maximum recorded reading, allowing for new peak measurements to be captured from a specific point in time.
