phone jammer will protect the examination room

 phone jammer is also used in the prison, detention house, court, police station and so on which have requirements for the secrecy.
The test software using Chinese interface design, easy operation, either a complete base station, repeater complete automated testing and test results of the project output, can also be an indicator of the individual tests. Switching between the test system, test path selection and establishment of communication link, through software control instruments and radio interface unit automatically, without manual connection. Plastic parts due to the stress or the top of the imbalance caused by the plane variant. As the plastic parts of the package tight force (large local density), the top ejector region by powerful white printed output produced or raised (by reducing the pressure of the solution). Injection pressure due to insufficient or poor mold cavity exhaust and other reasons, the molten resin can not reach the cavity caused by a corner shot of inadequate material phenomenon. Plastic resin in the surface along the flow direction by showing the silver stripes. Products leaving the surface of the gate emerged as the center of the ring-like stripes. Plastic surface in the local black plastic coke. Injection pressure is too large or because the cavity is not smooth, the edges of the mold caused by abrasion. Due to stress or mechanical damage caused by the product of small cracks or cracks. Lighting: 100W cool white fluorescent light source from the measured surface 500 ~ 550mm (illumination to 500 ~ 550Lux). Check the quality of the appearance of the parts to meet the requirements; lenses correct mounting location, no warping and loose, and left and right tilt is not greater than 3 °; from the front of the lens area, face 90 ° ± 15 ° (left and right rotation) should not see the screen washer; when not in 90 ° ± 15 ° of visual display within the scope allowed to see the washer, but the washer to tidy; visual display up and down so do not see the offset, can not see the boot screen shows obvious tilt. (Requiring the display of the centerline and the centerline of the lens up and down between the offset of less than 0.2mm, left and right sides of the tilt is not greater than 3 °). phone jammer will protect the examination room and meeting room environment.
Power test display brightness uniformity and color consistency; shell before and after the shell gap between the uniform, and less than (design decorative line width +0.2 mm), uniform and less poor segment (segment design poor +0.15 mm); after the shell the gap between the battery cover and uniform, and less than (design decorative line width +0.2 mm), uniform and less poor segment (segment design poor +0.15 mm); and on the flip, the flip with a uniform gap between the shell , and less than (design gap +0.2 mm), uniform and less poor segment (segment design poor +0.15 mm); lens, with a keyboard with the gap between the shell evenly; the keys are functioning properly, and feel uniform; antenna must be tightened, the gap junction to close and uniform; the flexibility of the normal battery snaps, battery easily removable
