Product Description

  SZ Vodasafe AJ11 Anti-Recording Device
The SZ Vodasafe AJ11 is an advanced anti-recording device designed to protect sensitive voice information from unauthorized recording. Adopting the industry-leading acoustic interference technology, it differs from traditional electromagnetic interference models and is harmless to the human body. By emitting inaudible sound waves that mix high and low-frequency sound sources, the device effectively interferes with digital recording equipment, preventing post-recording data recovery and safeguarding your confidential communications against illegal recording via mobile phones, voice recorders, and other devices.
Features
360-Degree Protection: Offers maximum 360° anti-recording coverage, ensuring all-around shielding without blind spots.
Acoustic Interference Technology: Emits human-inaudible sound waves to disrupt recording devices, avoiding harm to the human body while ensuring reliable protection.
Multiple Output Modes: Equipped with three toggle switch options to activate different output hole combinations (front & upper, right & upper, left & upper), adapting to various usage scenarios.
Large Battery Capacity: 8000mAH/12.6V high-capacity battery provides long-lasting usage time, meeting the needs of extended meetings or outdoor activities.
Intuitive Power Indication: Four middle working indicators show remaining power (100% for 4 lights, 75% for 3 lights, 50% for 2 lights, 25% for 1 light), with a quick four-blink then off prompt when the switch is turned on.

Technical Specifications

Quick Start Guide
Power Activation: Toggle any of the three switches (1.Front & upper output holes, 2.Right & upper output holes, 3.Left & upper output holes) to turn on the device.
Power Check: Observe the middle working indicators to confirm remaining power after the four quick blinks.
Optimal Placement: Place the device in an unobstructed location, ensuring the output direction is not blocked.
Charging Operation: Connect the charging cable to the charging port; the red and blue lights will illuminate during charging, and only the red light remains on when fully charged.
Important Notes
1.The device is not waterproof; always place it in a dry environment.
2.Do not block the output direction during use. Placing it in a bag or pocket will reduce shielding effectiveness.
3.When the anti-recording function is activated, it may interfere with phone calls and microphones. Maintain a distance of over 5 meters from such devices.
4.Avoid using the device directly facing individuals wearing hearing aids.
5.Do not use the device while charging for extended periods, as this may cause overheating and equipment failure.
6.Suboptimal usage scenarios include operating beyond the effective range, having obstructions, incorrect angles, or placing the device too close to the audio source.

FAQ for AJ11
1. How does the SZ Vodasafe AJ11 achieve anti-recording?
It adopts acoustic interference technology, emitting inaudible high and low-frequency mixed sound waves that disrupt digital recording equipment. This prevents the recording of clear voice information and blocks post-recording data recovery.
2. Is the device harmful to the human body?
No. Unlike traditional electromagnetic interference models, the AJ11 uses acoustic interference that is inaudible to the human ear and harmless to the human body.
3. How do I check the remaining power of the device?
After turning on the device via any toggle switch, the four middle working indicators will show the power level: 4 lights for 100%, 3 lights for 75%, 2 lights for 50%, and 1 light for 25%. Note that the indicators will blink four times quickly and then turn off after switching on.
4. What should I do if the shielding effect is poor?
First, ensure the output direction is not blocked (avoid placing it in a bag or pocket). Then, check if the device is within the effective range and free from obstructions. Adjust the placement angle to ensure 360° coverage and avoid being too close to the audio source.

5. Can I use the device while charging?
It is not recommended for extended use while charging. Long-term simultaneous charging and usage may cause the device to overheat, leading to malfunctions.
6. Why does the device interfere with my phone calls?
The acoustic interference technology used by the AJ11 may affect phone microphones. Maintain a distance of over 5 meters between the device and your phone when using the anti-recording function.
7. What is the effective range of the anti-recording function?
The device provides 360° maximum coverage, but for optimal results, use it within a reasonable range and avoid operating beyond the specified effective distance (refer to product actual performance).
8. How long does the battery last on a full charge?
The battery capacity is 8000mAH/12.6V, and the usage time depends on the working mode and frequency. Under normal conditions, it can support extended periods of use to meet daily needs such as meetings and outdoor activities.
9. Can I use the device outdoors?
Yes, but ensure it is placed in a dry environment (the device is not waterproof) and avoid exposing it to rain or moisture. Also, ensure there are no obstructions blocking the output direction.
10. What should I do if the charging indicators do not light up?
First, check if the charging cable and power adapter are functioning properly. Then, confirm the charging port is connected securely. If the issue persists, contact SZ Vodasafe customer service for assistance.
