Four, installation and use instructions
4.1 installation steps and methods
4.1.1 remove the shield machine from the box.
4.1.2 turns the antenna into its respective antenna pedestal,
otherwise it will not be effective.
4.1.3 put the shield on the wall or the corresponding location, the
best installation height is 1-2 meters.
4.1.4 first make sure that the shield machine is full of
electricity, then turn on the power switch. The power indicator on
the power supply indicates that it is starting to work.
4.2 matters of attention
4.2.1 must first install the antenna according to the corresponding
identification on the host, and then connect the main power supply.
The effective coverage of the 4.2.2 shield is a circular area with
the center of the shield, so it is careful to choose the placement
position of the shield in order to avoid the shielding dead angle.
The 4.2.3 shield should be placed in a well ventilated place,
avoiding the shielding of large objects and avoiding the strong
electric and magnetic sources of the strong heat source, so as to
ensure the shielding effectiveness and long stable work.
4.2.4 shields should not stack other items and dismantle the
antenna when they work, so as not to affect the shielding effect
and damage the machine.
When the 4.2.5 shield is not in use, it should cut off the power in
time, so as not to affect the normal use of the mobile phone.
4.2.7 should pay attention to waterproofing when using shields
outside.
4.2.7 when the area of the site is larger than the effective
shielding range, it is recommended to adopt multiple shielding
honeycomb installations to ensure shielding effectiveness.
4.2.8 because the power supply and antenna are matched with the
main engine, they are debugged one by one when they are debugged.
Please try not to use them interchangeably, so as to ensure the
best effect.
4.2.9 please keep away from corrosive gases and liquids and do well
in dust prevention and moisture prevention, so as not to accelerate
the aging of internal components of equipment.
When placing 4.2.10 outside or in the wild, we should pay attention
to adding protection devices to rats and ants.
Five. Maintenance and maintenance
5.1 the spacetime shield is a maintenance free device without
maintenance.
5.2 when surface cleaning is done, chemical solvents should be
banned and water inflow should be avoided.
5.3 shields should be stored in dry and ventilated places when they
are useful, so as to avoid prolonged exposure to salt spray and
harmful gases.
5.4 shields warranty period of one year, life-long maintenance.
Six. The answer to the problem
6.1 when the signal jammers work, why do some cell phone signals
still indicate signals?
Answer: This is just an illusion. In fact, the mobile phone is
already unable to communicate. When you press the pull button at
random, you will find that there is no signal indication on the
signal indicator.
6.2 will the signal shield interfere with the normal operation of
other electronic devices?
Answer: No, no. This is because the electromagnetic signals emitted
by the signal shields fall entirely within the prescribed mobile
phone working frequency band, which only blocks the communication
of mobile phones. This signal is always in a relatively static
state, and will not affect any electronic device.
6.3 is the signal shielding device harmful to human body and cell
phone?
Answer: please feel relieved that the intensity of the
electromagnetic signal emitted by the blooad space-time signal
shield is very weak, and has passed the Guangdong Provincial Health
Bureau, the microwave radiation test certification, and the test
data show that the intensity of this signal is far from harm to the
human body. At the same time, the signal shield is only blocking
the forward signal of the mobile phone, so that the cell phone can
not contact the base station, so it will not cause any damage to
the phone itself.
6.4 is there any difference in the distance between the signal
shields when used indoors and outdoors?
Answer: Yes. The effective distance of the signal shield (1-40
meters, depending on the distance between different environments)
generally refers to the indoor distance. In outdoor open areas, the
effective distance of shielding can reach several hundred meters.
It should be pointed out that, whether in indoor or outdoor use,
the effective distance of the shield is related to the environment
conditions at that time, such as the distance from the base
station, the location of the place and so on. Therefore, when using
the signal shield, we should give full consideration to this factor
and avoid shielding dead angle, thus affecting the shielding
effect.
6.5 does the signal shield have the same effect on GSM phones and
CDMA phones?
Answer: this question is a good question. Because the
anti-interference performance of the CDMA mobile phone is far
superior to the GSM mobile phone, the effective shielding distance
of the signal shield for the CDMA cell phone is less than that of
the GSM cell phone, but the difference is not very large, about 2-4
meters. But it also asks the user to pay attention to some
particularly important places, and should increase the number of
field signal shields when necessary in order to ensure the
shielding effectiveness of the CDMA mobile phone.
6.6 when the signal shield is working for a period of time, the
shell is hot. Will it damage the machine for a long time?
Answer: Thank you for your careful, this is a normal phenomenon. In
design, we use the thermal conductivity of aluminum alloy wire
drawing shell to assist heat dissipation. It can guarantee long
time stable work. As a result, the machine will not be damaged by
the heat of the shell.
