1. Product Features
(1) Product function overview:
The vehicle-mounted hand-held cell phone jammer is a wide-band transmitter with transmission frequencies of 870～880MHz, 930～960 MHz, 1805～1920MHz, 2010～2145MHz, 2400～2500MHz, 2300～2370MHZ, 2555～2655MHZ (excluding GSM, DCS, PCS, 4G uplink operating frequency), is a wireless device used to intercept the signal between the transmitter (base station) and the mobile phone, and can shield 2.4 wireless signals.
This product can effectively shield the microwave signal between the transmitter (base station) and the mobile phone, so that the mobile phone in the area that needs to be shielded (including GSM, CDMA, DCS, PHS, 3G, 4G) can be disconnected from the outside world. This product is small in size and easy to use. It can be applied to a variety of environments with different areas through separate and distributed placement.
2. Installation and use instructions
2.1 Installation steps and methods
2.1.1 Take out the jammer host from the box;
2.1.2 Screw the antennas of the vehicle-mounted handheld mobile phone signal jammer into their respective antenna holders, otherwise it will be invalid;
2.1.3 Hang the jammer on the wall or corresponding position, the best installation height is 1-1.8 meters;
2.1.4 First connect the 5V output of the power supply to the host, then plug the AC input of the power supply into the mains socket, and then turn on the power switch, the work indicator on the power supply is on to indicate the start of work
Three, matters needing attention
3.2.1 The antenna must be installed according to the corresponding mark on the host first, and then the host must be powered on.
3.2.2 The effective coverage of the shield is a circular area centered on the shield, so when using it, pay attention to the correct placement of the shield to avoid shielding blind spots.
3.2.3 The shield should be placed in a well-ventilated place, avoid large objects as much as possible, and avoid strong electromagnetic sources of strong heat sources to ensure the shielding effect and long-term stable operation.
3.2.4 When the shield is working, it is not allowed to stack other objects and disassemble the antenna, so as not to affect the shielding effect and damage the machine.
3.2.5 When the vehicle-mounted handheld mobile phone signal jammer is not in use, the power supply should be cut off in time to avoid affecting the normal use of the mobile phone.
3.2.7 When using the shielding device outdoors, pay attention to waterproofing.
3.2.7 When the area of the site used is larger than the effective shielding range, it is recommended to use multiple shields for honeycomb installation to ensure the shielding effect.
3.2.8 Since the power supply and antenna are dedicated to the host, and are debugged one-to-one during factory debugging, please try not to interchange them to ensure the best results.
3.2.9 Please stay away from corrosive gases and liquids, and do a good job of preventing dust and moisture, so as not to accelerate the aging of the internal components of the equipment.
3.2.10 When placed outdoors or in the wild, pay attention to adding protective devices in the environment where destructive animals such as rats and ants are infested.
