FAQ:
Why is there still a signal on the phone's signal indicator when it
works?
A: It's just an illusion.In fact, the mobile phone has been unable
to communicate.When you press the pull button, you will find that
there is no signal on the signal indicator.The cell phone signal
shield will not interfere with the normal work of other electronic
devices. The antenna should be installed on the corresponding signs
of each channel on the host, and then connected to the host power
supply.
Are cell phone signal Jammer harmful to people and mobile phones?
A: Please rest assured that the electromagnetic signal intensity
emitted by the cell phone signal Jammer is very weak. The test data
indicates that this signal strength is far from harmful to the
human body.At the same time, the mobile phone signal shield is just
blocking the forward signal of the phone, so that the cell phone
cannot be connected with the base station, so there will be no
damage to the phone itself.
Is the cellular signal shield the same for GSM mobile phones and
CDMA mobile phones?
A: that's a good question.Because CDMA mobile phone's
anti-interference performance is far superior to that of GSM mobile
phone, the effective shielding distance for CDMA mobile phone is
smaller than that of GSM mobile phone, but the difference is not
very large, about 2-4 meters.But it also reminds users to pay
attention to some particularly important sites, and should increase
the number of mobile phone signal blockers when necessary to ensure
the shielding effect of CDMA mobile phones.
After working for a period of time, the mobile phone signal mask is
hot. Will working long hours damage the machine?
A: thank you for your care. This is a normal phenomenon.In the
design, we use the thermal conductivity of aluminum alloy to assist
the heat dissipation.This can guarantee long time stable work.As a
result, the machine will not damage the machine.
