Device Components & Functional Introduction
The VS-AJ120's design prioritizes both performance and usability, with clearly labeled components and intuitive controls. Below is a detailed breakdown of its key parts and their functions:
Three-Side Signal Transmitting Terminals: Located on the front, left, and right sides of the main unit. These terminals emit ultrasonic signals to block recording devices (e.g., smartphones, voice recorders) within the shielding range. For optimal results, align terminals directly with potential recording sources.
LED Display Screen: A high-visibility screen that shows real-time statuses, including:
Air quality level (indicates indoor air purity)
Power level (battery or AC power status)
UV lamp status (on/off/timer)
Working mode (auto/manual for air purification)
Anion function status (on/off)
Fan gear (1/2/3 for manual mode) and fan working status
Function Buttons:
"M" Button: The core control for air purification modes and anion function (short press for mode switching, long press for anion activation/deactivation).
Light Button: Controls the night light (short press) and UV sterilization lamp (long press).
UV Lamp Switch: A dedicated physical switch for emergency shutdown of the UV lamp (complementary to the Light Button).
Air Purification Power Off Switch: Cuts power to the air purification module independently (does not affect anti-recording jamming).
Power Adjustment Knobs: Three knobs (one for each signal transmitting terminal) to fine-tune jamming power:
Clockwise rotation: Increases power (extends shielding distance).
Counterclockwise rotation: Decreases power (reduces energy consumption).
Labeled for direction (front/left/right of the main unit) for precise control.
Power Adapter Interface: Connects to the included AC adapter for continuous power supply.

1st short press: Auto Mode. The fan automatically adjusts its gear (1/2/3) based on real-time air quality (higher gear for poorer air quality).
2nd short press: Manual Mode 1 (low fan speed, energy-saving for mild air purification).
3rd short press: Manual Mode 2 (medium fan speed, balanced purification).
4th short press: Manual Mode 3 (high fan speed, maximum purification for polluted air).
5th short press: Shuts down the air purification module (anti-recording jamming remains active if enabled).
Anion Function (Long Press "M"):
1st long press: Turns on the anion generator (improves air freshness, ideal for dry environments).
2nd long press: Turns off the anion generator.
Anti-Recording Jamming Operation
Activate and adjust the jamming function via the remote control and power knobs:
Turn On Jamming: Press the Remote Control Boot Button (labeled "ON"). The LED screen will display a "Jamming Active" indicator (varies by screen design).
Adjust Jamming Power:
Use the three power adjustment knobs to match the environment. For example:
Increase power for large rooms (up to 5m shielding distance).
Decrease power for small spaces (2m minimum distance) to avoid unnecessary energy use.
Align the signal transmitting terminals directly with potential recording devices (e.g., a visitor's smartphone on the table) for the best shielding effect.
Turn Off Jamming: Press the Remote Control Shutdown Button (labeled "OFF"). The "Jamming Active" indicator will disappear.
Additional Functions
Night Light: Short press the Light Button to turn on/off the soft night light (ideal for low-light environments like evening meetings).

On-Site Installation & Layout Guidelines
The VS-AJ120's shielding effectiveness depends on proper placement. Follow these scenario-specific guidelines to protect confidential conversations:
Scenario 1: Face-to-Face Meetings with a Table (e.g., Offices, Reception Areas)
Application: Protects corporate leaders or key speakers from being recorded by visitors.
Layout:
1.Place the VS-AJ120 on the table between the leader (left seat) and visitors (right seats, 1~2 people).
2.Align the front signal transmitting terminal toward the visitors (to block their recording devices).
3.Adjust the front power knob to ensure the visitors' seats are within the 2~5m shielding range.
Goal: Prevent recording of the leader's voice (recording of the visitors' own voices is irrelevant and does not impact privacy).
Scenario 2: Sofa Conversations (e.g., Living Rooms, Small Meeting Rooms)
Application: Casual confidential talks between hosts and guests.
Layout:
1.Place the VS-AJ120 on the coffee table between the host and guest.
2.For targeted protection: Align the signal transmitting terminals toward the guest's seating area (if the host's voice needs shielding).
3.For general protection: Position the device in the center of the coffee table to cover a 180° range (matches the VS-AJ120's function angle).
Recommendation: Use 1 unit of VS-AJ120 for small sofa areas (up to 4 people).
Critical Installation Tips
No Obstacles: Ensure no objects (e.g., books, cups, laptops) block the signal transmitting terminals-obstacles reduce shielding range.
Test First: After placement, use a test recording device (e.g., smartphone) to verify shielding effectiveness. Adjust the power knobs if recording is still possible.
Multiple Units for Large Spaces: If the VS-AJ120's 2~5m range is insufficient (e.g., large conference rooms) or shielding is ineffective for some devices, use 2+ units or pair with other SZ Vodasafe anti-recording products.
