Watch and learn proper calibration and sensor use:

Annotated PSB7‑PRO Overview

Key components UX-design features to note:

• Backlit Display & Flashlight – perfect for low-light investigations

• Sweep Speed & Step Controls – adjust FM/AM sweep timing and granularity

• Trigger Sensors (REM & IR) – toggle for motion-activated responses

• Temperature & Alert Controls – detect ambient changes that might correlate with EVPs

• Mute Mode & Manual Sweep – minimize audio clutter and isolate genuine hits

✅ Calibration Checklist Infographic

1. Power On & Antenna Check

   Hold POWER for 3 seconds, extend antenna fully, switch reception ON.

2. Sensor Setup

   Choose trigger mode: REM, IR, or both; set sweep timer to “00s” for manual entry.

3. Sweep Configuration

   Set FM step size (~40 kHz); choose sweep rate (e.g., 170 ms) for balanced clarity and sweep rate

4. Backlight & Mute Mode

   Activate backlight; use MUTE to silence until sensor triggers, avoiding background noise.

5. Temperature Monitoring

   Enable ambient + deviation display; audible alert on ±1 °C changes helps flag anomalies.

6. Sound & Threshold Settings

   Set volume moderate; enable audible alert for temperature or sensor triggers.

7. Field Test Run

   Sweep forward manually to test clarity; note minimum ghost/noise interference.

8. Capture & Document

   Record results; adjust sweep speed or step size based on clarity and response length.

Why It Matters

“When used by a properly trained individual… the PSB7‑PRO will provide results similar to an EVP recorder, but in real time.”

This calibration method uses Gary’s precise sweep settings and sensor configurations to filter out static noise and focus on voice anomalies. By fine-tuning sweep rates, enabling MUTE mode, and tracking temp shifts, you build a reliable environment for genuine spirit presence.

Pro Tips from Gary

• REM-triggered sweeps allow spirits to “activate” the device silently.

• Use small frequency steps to access overlapping radio “hotspots” for more fluent EVP generation.

• Always extend the antenna fully when sweeping FM to improve reception.

Wrap‑Up

Calibrating your PSB7‑PRO correctly is the foundation of powerful spirit communication. With precise sweep configurations, sensor-triggered modes, and temp monitoring, you're not just scanning frequencies—you’re engineering an invitation for the unseen to speak. Document your setup, test, and refine—because clarity comes from preparation.
