Package Content:

1. take out the device

2. screw the antenna to the right position according to the main unit indicated and put on the DIP switch (otherwise the jammer can not work)

3. switch on the electricity, the red light on, the jammer is working.

4. when the jamming range coming to dwindle, it shows the battery is going to out of work, should be charged. 

(When charging, the charging indicators on the AC charger and the device will light red; After fully charged, the charging indicators will turn green).

5. since the valid scope covered by the jammer is a round area with the jammer as the center, put the jammer in the center place if possible to achieve a better shielding effect.

6. please keep away strong electromagnetic sources with heat sources to ensure good shielding effect and stable operation for a long time.

7. please don’t use it for a long time by continuous charging, otherwise the battery life will be shorten.

8. after use, please switch off the device in time to avoid affecting the normal use of the phone.

9. while using it outdoors, be sure to keep it away from water or damp.
