Shielder basic knowledge installation and use instructions
1. Take out the main shield machine from the packaging box;
2 Screw the antennas into their respective corresponding antenna
seats, otherwise they will be invalid;
3 Hang the shield on the wall or the corresponding position, and
the best installation height is 1-2 meters;
4 Turn on the switch of the power supply, and the working indicator
light on the power supply indicates to start working. If it is a
built-in lithium battery, please make sure it is fully charged
before use.
Matters needing attention
1 the antenna must be installed according to the corresponding
identification on the host before turning on the host power supply.
2 The effective coverage area of the shield is a circular area
centered on the shield, so pay attention to correctly selecting the
placement position of the shield to avoid shielding dead angle; If
it is a directional antenna, the alignment direction can be
adjusted according to the standard sector angle of the antenna.
3 Shielders should be placed in well-ventilated places, avoiding
large objects and strong electromagnetic sources with strong heat
sources as far as possible to ensure shielding effect and long-term
stable work.
4 When the shielding device is working, it is not allowed to stack
other articles and disassemble the antenna, so as not to affect the
shielding effect and damage the machine.
5 When the shield is not in use, the power should be cut off in
time, so as not to affect the normal use of the mobile phone.
6 When using the shield outdoors, attention should be paid to
dustproof and waterproof. Please keep away from corrosive gases and
liquids, and do a good job of dustproof and moistureproof, so as
not to accelerate the aging of internal components of the equipment
7 When the area of the site used is larger than the effective
shielding range, it is recommended to install several shields in
honeycomb to ensure the shielding effect.
8 Since the power supply and antenna are used exclusively with the
host, and they are debugged in one-to-one correspondence during
factory debugging, please try not to use them interchangeably to
ensure the best effect.
