Installation & Operation Guide
Step 1: Unboxing & Inspection
Carefully open the packaging and retain the box for future transportation or storage.
Inspect all components (jammer unit, control panel, antennas, cables, battery) for completeness and damage. Contact SZ Vodasafe or your supplier immediately if any parts are missing or defective.
Step 2: Connection Setup
Antenna Installation: First, securely fix all antennas in place (ensure stable mounting to avoid signal loss or damage). Use the coaxial cable to connect each antenna to the corresponding CH1-CH13 RF Output Port on the jammer (one-to-one connection).
Critical Warning: Never start the jammer without connecting all antennas. Operating the device without antennas will cause severe damage, and all resulting costs and consequences are the responsibility of the user.
Remote Controller Connection: Connect the remote control box to the jammer's RCU Port. Align the red dot on the cable plug with the red dot on the port socket for proper insertion (incorrect alignment will prevent connection).
Power Connection: Plug the AC 110-220V power cable into the jammer's power input port.
Step 3: Power On the Jammer
Toggle the orange power switch on the front panel of the jammer to the "ON" position (top position).
The jammer defaults to 25% output power upon startup. Adjust the power level as needed based on on-site requirements (see Step 4 for power adjustment).
Step 4: Operation & Control
All operations of the VS-VJX8 are performed via the remote control box, which features function shortcuts and an on-screen menu for comprehensive control.

Shielding Performance & Working Principle
Working Principle
Wireless communication relies on a sufficient carrier-to-interference ratio (SNR) for successful signal reception. The VS-VJX8 generates interference signals with the same frequency as target wireless devices (e.g., mobile phones), disrupting their ability to receive base station signals. This severs the communication link between the device and the base station, achieving effective signal shielding without affecting other electronic equipment.
The shielding radius is determined by the jammer's output power, antenna gain, path attenuation, and base station signal strength, calculated using the formula:
Pch + Gat - L0 ≥ Prx
Pch: Minimum channel output power of the jammer
Gat: Antenna gain
L0: Path attenuation (L0 = 32.4 + 20logd + 20logf + FAF; d = distance in km, f = frequency in MHz, FAF = 6 dB path loss increment)
Prx: Base station signal strength
Distance & Attenuation Reference Table

Distance (m)	900 MHz Attenuation (dB)	1800 MHz Attenuation (dB)	Distance (m)	900 MHz Attenuation (dB)	1800 MHz Attenuation (dB)
1	38	44	40	70	81
2	44	50	50	72	83
3	47	53	100	78	89
5	52	58	200	84	90
10	58	69	300	87	93
15	61	70	500	92	98
20	64	74	1000	98	104

Typical Test Results
Tested with professional equipment (ADVANTEST U4941 Spectrum Analyzer, Safety Certification TEST Road Tester, MOTOROLA V8088 Test Phone) in environments with base station signal levels of RxLev -50dBm to -70dBm, the VS-VJX8 consistently achieves a maximum shielding radius of 300 meters, effectively blocking GSM, CDMA, and other common wireless signals.
Safety Warnings & Precautions
Mount antennas vertically in the direction of the ground for optimal signal coverage.
Always connect antennas before powering on the jammer; do not disconnect antennas during operation.
Place the jammer in a well-ventilated area, avoiding obstruction by large objects that may block signal transmission or heat dissipation.
For outdoor use, ensure the device is protected from water and fire. Do not operate in humid, high-pressure, high-temperature, or strong magnetic field environments.
If the jammer malfunctions (e.g., no power, abnormal indicators), contact SZ Vodasafe or your authorized dealer. Do not disassemble or repair the device yourself.
SZ Vodasafe is not responsible for free repairs or replacements due to damage caused by improper operation, unauthorized disassembly, or neglect of safety precautions.

Frequently Asked Questions (FAQs)
Q1: Will the VS-VJX8 interfere with other electronic devices?
A1: No. The electromagnetic signals emitted by the jammer are strictly limited to the legal working frequency bands of mobile phones and target wireless devices. It only shields specific communication signals and does not affect the normal operation of other electronic equipment.
Q2: Is the jammer harmful to humans or mobile phones?
A2: No. The electromagnetic signal strength of the VS-VJX8 is extremely low, far below the safety limits specified by international health standards, and poses no harm to human health. Additionally, the jammer only blocks base station downlink signals, preventing mobile phones from establishing connections-this does not cause any physical or functional damage to mobile phones.
Q3: Is there a difference in shielding distance between indoor and outdoor use?
A3: Yes. Outdoor environments typically have stronger base station signals, which may slightly reduce the effective shielding distance compared to indoor use. In general, the shielding range depends on the local electromagnetic environment, distance from the base station, and installation location. The VS-VJX8's 100-300 meter range is tested under standard conditions; adjust power output as needed for optimal performance.
Q4: Does the jammer work equally well for GSM and CDMA phones?
A4: CDMA phones have stronger anti-interference capabilities than GSM phones. As a result, the effective shielding distance for CDMA phones may be slightly shorter than for GSM phones. The VS-VJX8's high output power and precise frequency tuning minimize this difference, ensuring reliable shielding for both types of devices.
Q5: Is it normal for the jammer's casing to heat up during use? Will long-term operation damage the device?
A5: Casing heating is a normal phenomenon. The VS-VJX8 uses a metal casing with excellent thermal conductivity to assist in heat dissipation, a key design feature for stable long-term operation. The heating does not affect the device's performance or lifespan-rest assured to use it continuously as needed.
