4.1 installation steps and methods

4.4.1 blockers hosts out of the box;

4.1.2 antenna screwing in respective of the corresponding antenna, otherwise is invalid;

4.1.3 the shielding device on the wall or the corresponding position, the best installation for 1 to 2 meters high;

4.1.4 determine blockers host has been charged, and then open the power switch, power indicator according to begin to work on the work

4.2 matters needing attention

2 must first install the antenna according to the corresponding identification host, to host the power is connected.

4.2.2 immobilizer is effective coverage of immobilizer centered round area, so pay attention to when using correct selection of the location of the immobilizer lest produce block corner.

Holdings blockers should be placed in ventilated good place, as far as possible to avoid large objects block, to avoid the strong heat source of the strong electromagnetic source, to ensure that the shielding effect and work stably for a long time.

4.2.4 blockers, shall not pile up on the other items and remove the antenna, lest affect shielding effect and damage the machine.

4.2.5 blockers when not in use, should be timely cut off power supply, so as not to affect the normal use of mobile phones.

4.2.7 the outdoor use blockers, waterproof should be paid attention to.

4.2.7 when using the site area is greater than the effective shielding range, the proposal USES more than one blockers cellular installation, to ensure that the shielding effect.

4.2.8 due to power supply, antenna is matched with the host is special, and the factory is one to one correspondence debugging when debugging, please do not used interchangeably, as far as possible to ensure the best results.

4.2.9 please far away from the corrosive gas and liquid, and make dust prevention, so as not to accelerate the equipment aging of the internal components.

4.2.10 placed outdoors or field when, should pay attention to rats, ants and other destructive added in the environmental protection of animals.

Five, the maintenance

5.1 the immobilizer belong to free maintenance equipment, without maintenance.

5.2 to wipe on the surface, cut the use of chemical solvents, and avoid the water in the machine.

5.3 blockers useful, should be stored in dry and ventilated place, avoid prolonged contact salt fog and harmful gas.

5.4 the immobilizer warranty for a year, life-long maintenance.

Six, problem solving

6.1 signal shielding device is working, why some cell phone signals instructions still have instructions?

A: it's just an illusion. In fact, at this time of mobile phone has been unable to communicate. When you press the draw button, you will find, no indicator on the signal indicator.

6.2 signal blockers will not interfere with other electronic equipment to work normally?

A: no. This is because, the signal shielding electromagnetic signals completely fall within the provisions of the state of working frequency band, will only have blocking effects on mobile communication. And the signal is still a relatively static state, will not affect any electronic equipment.

6.3 signal shielding and mobile phones are harmful to human body?

Answer: please rest assured that the launch of the electromagnetic signal strength is very weak signal shielding device, test data show that the signal strength far will not pose a harm to human body. Just stop at the same time, the signal immobilizer to signal before mobile phone, cell phone can't contact with the base station, therefore do not have any damage on the phone itself.

6.4 signal blockers in the indoor and outdoor use range is there a difference?

A: there are. The effective distance signal shielding device (30-40 meters) generally refers to the interior. In outdoor open terrain, shielding the effective distance of a few hundred meters. It should be pointed out that both indoors and outdoors, the effective distance of the block and the environmental conditions at that time have a certain relationship, such as from the base station near and far, placed, etc. When using the signal shielding device, therefore, should fully consider the factor, avoid to produce shielding corner which affect shielding effect.

6.5 signal shielding effect as the function of GSM mobile phones and CDMA mobile phone?

A: that's a good question. Because of CDMA mobile phone anti-jamming performance is much better than the GSM mobile phone, as a result, signal shielding device for effective shielding distance less than CDMA mobile GSM mobile phone, but the difference is not very big, about 2 to 4 m. But also to remind users are especially important in some places, when necessary, should increase the number of field signal shielding device, to ensure that the shielding effect of CDMA mobile phone.

6.6 after working for a period of time of the signal shielding casing hot, working long hours can not damage the machine?

A: thank you for your careful, this is a normal phenomenon. Design, we use the thermal conductivity of the aluminum alloy wire drawing chassis to aid cooling. Able to ensure to work stably for a long time. Therefore, casing hot won't damage the machine.
