At present, mobile phone signal jammers have been widely used in examination rooms, prisons and other places. To be honest, I really don’t know how long this thing will last, but doing the following points can greatly extend the service life of cell phone jammer:
1. The antenna must be installed before turning on the power.
2. The shield should be placed in a well-ventilated place, avoid large objects as much as possible, avoid strong heat sources and strong electromagnetic sources, so as to maintain the effect of the shield and work for a long time.
3. If the power supply of the mobile phone signal jammer is not industrial grade, remember not to use it without disconnecting it for 24 hours, otherwise the power supply and the machine life will be shortened.
4. Because the product does not have a power switch, it is recommended to use a power socket with a switch.
5. When wiping the surface, do not use chemical solvents and avoid water entering the machine.
6. When the shield is not in use, it should be stored in a dry and ventilated place to avoid prolonged exposure to salt spray and harmful gases
7. When the jammer is working, do not put other objects on it and disassemble the antenna, so as not to affect the effect of the jammer and damage the host
8. The mobile phone signal shielding antenna of the external antenna must not be screwed up wrongly, and screwed up corresponding to the frequency
9. The installation location of the mobile phone signal jammer should be far away from high temperature and humid places. When using the jammer outdoors, pay attention to waterproofing
10. Do not use a completely sealed box to cover the cell phone signal jammer for hiding, as this will affect heat dissipation and cause damage to the machine.
