Features
Multi-Band Signal Shielding
Targets three widely used remote control frequencies (315MHz, 434MHz, 868MHz) that are commonly employed in car remotes, electric vehicle remotes, access control systems, remote-controlled doors, remote weighbridges, and various wireless cheating devices. The device effectively blocks both ASK and FSK modulation signals, ensuring comprehensive coverage of potential interference sources.
Adjustable Shielding Control
Equipped with dual independent switches for precise frequency management:
Green Power Switch: Activates 868MHz signal shielding (blue indicator light on); press again to deactivate.
Red Power Switch: Activates 315MHz and 434MHz signal shielding (red indicator light on); press again to deactivate.
This design allows users to tailor the shielding range to specific needs, conserving battery life and avoiding unnecessary interference.
High Power & Reliable Performance
Built with a high-power FSK/FM wireless transmitter, the VS-RC03A maintains stable signal blocking even in complex environments. The 1600mAh rechargeable lithium battery provides long-lasting operation, while the included DC9V/1A power adapter ensures convenient recharging (2-3 hours for a full charge from 50% factory power).
Compact & Durable Design
Crafted from premium ABS plastic, the device is lightweight, impact-resistant, and designed for long-term use. Its compact dimensions (130×130×35mm) make it easy to place discreetly in any environment, while the external antennas (screw-on design) ensure optimal signal transmission and shielding efficiency.
Customizable Frequency Options
In addition to the default 315/434/868MHz frequency range, SZ Vodasafe offers customization services to adjust the operating frequencies according to specific customer requirements. This flexibility makes the VS-RC03A adaptable to unique security scenarios and regional frequency standards.
Applications
The SZ Vodasafe VS-RC03A is engineered for use in a wide range of professional and institutional settings, including:
Examination Rooms: Prevents cheating via wireless remote-controlled devices (e.g., hidden earpieces, signal transmitters) to ensure fair and honest testing.
Conference Centers & Boardrooms: Blocks unauthorized remote access to confidential documents, presentation equipment, or recording devices, safeguarding sensitive information.
Hotels & Resorts: Enhances guest security by preventing remote interference with room locks, electronic safes, or other in-room devices.
Commercial Facilities: Stops fraudulent activities involving remote weighbridges, vending machines, or industrial control systems that rely on wireless remote signals.
Government & Facilities: Provides an additional layer of security by blocking unauthorized remote control of restricted equipment or access points.
Educational Institutions: Secures classrooms, auditoriums, and testing centers from signal-based cheating tools.
Usage Instructions
Step 1: Unboxing & Antenna Installation
Open the package and remove the VS-RC03A jammer, power adapter, and user manual.
Screw the three dedicated antennas firmly into the corresponding antenna sockets on the back of the device (ANT1: 315MHz, ANT2: 434MHz, ANT3: 868MHz - left to right). Ensure antennas are tightened securely to avoid signal loss or abnormal operation.
Step 2: Charging the Device
Connect the included DC9V/1A power adapter to the device's power input port.
Plug the adapter into a standard electrical outlet. Charge the device for 2-3 hours before first use (the factory ships the product with approximately 50% battery power; low battery will impact shielding performance).
Disconnect the power adapter once fully charged. The built-in lithium battery allows for cordless use.
Step 3: Activating the Jammer
Place the device in a central location within the desired shielding area (ensure no obstacles block the antennas, as this may reduce the effective range).
To activate 868MHz shielding: Press the front green power switch. The blue indicator light will illuminate, and the device will begin emitting 868MHz signals to block corresponding remote controls.
To activate 315/434MHz shielding: Press the front red power switch. The red indicator light will illuminate, and the device will begin emitting 315MHz and 434MHz signals.
To deactivate a frequency band: Press the corresponding switch again (green for 868MHz, red for 315/434MHz). The indicator light will turn off, and signal transmission will stop.
Step 4: Optimal Placement
The effective shielding range is a circular area centered on the device. Position the VS-RC03A at a height of 1-2 meters (e.g., on a table, shelf, or mounting bracket) for maximum coverage.
Avoid placing the device near metal objects, walls, or other signal-blocking materials, as these may create "blind spots" in the shielding range.
For large spaces (e.g., conference halls), multiple units can be deployed to ensure full coverage.
Precautions for Safe & Effective Use
Use Dedicated Power Adapter Only: Never use a non-SZ Vodasafe power adapter, as this may damage the device, cause electrical hazards, or void the warranty.
Do Not Open the Device: The internal components carry electrical current. Opening the back cover may result in electric shock and will invalidate the warranty.
Power Management: Turn off the device and unplug the power adapter when not in use for extended periods (e.g., overnight, during travel) to conserve battery life and reduce energy consumption.
Environmental Considerations: Use the device in a well-ventilated, dry environment. Avoid exposure to direct sunlight, rain, water droplets, high temperatures (above 40°C/104°F), or high humidity (above 85%), as these conditions may damage the internal components.
Rational Use: The VS-RC03A will shield legitimate remote control signals (e.g., car remotes, access control systems) within its range. Use the device only in authorized areas and ensure it does not interfere with emergency services or critical infrastructure (e.g., medical equipment, fire alarms) - compliance with local regulations is the user's responsibility.
Warranty Information: SZ Vodasafe provides a standard warranty for the VS-RC03A (terms and conditions apply). Contact customer service for support, repairs, or replacements.
