Overview and Specifications:

1. Remove the antenna installed on the GPS device.
2. Insert the cigarette lighter corresponding to the car.
3. After the device is powered on, it works normally.
4. Remove the GPS signal masker directly during use. Monitor the speed of the platform, keep it in the unshielded position or move to 0. Note: When using the onboard GPS screen, please note the following:
1. The shielded antenna is intact.
2. Tighten the interface between the antenna and the instrument.
3. Whether the inserted instrument is in good contact with the cigarette holder of the cigarette.

Maintenance: 1 This guard is maintenance-free and requires no maintenance. 2 When wiping the surface, please cut off the use of chemical solvents to avoid water accumulation in the machine. 3 When the shield is useful, store it in a dry, well-ventilated area to avoid prolonged exposure to salt spray and harmful gases.

Product introduction:

The car GPS series signal shielding device is the third generation green GPS signal shielding device, which only shields the receiving signal of the on-site GPS terminal, and has no negative influence and interference on communication and transmission of other electronic devices around. This machine adopts dual output and can cover all kinds of GPS signals such as all positioning terminals within the range of 15-50 meters (depending on the strength of satellite signals), so that all GPS positioning terminals within the shielding range are completely connected with the outside world. Interrupted. The rated working voltage of this product is 12-24V. Both the cart and the trolley can be used directly, the working frequency bandwidth is 20MHz, the frequency range is: 1560-1580MHz; 1150-1250MHZ
