How to Install:

• Install this device at the height about 1.5-1.7m will get the best jamming result, keep this device in vertical.
• Never install this device close to the wall; the wall will affect the interference signals. Put this device 30-50cm away from the wall.
• One set of this device can block the GSM/CDMA/3G signals up to 15m radius, covers an individual room of around 700 square meters.
• To cover an area bigger than 700 square meters, please install multiples of this device to ensure better jamming effect, e.g. in an individual space of 900 square meters, you should need to install 2 devices working together.
• This device is not able to cover different spaces divided with walls. Install individual jammers in different partition of a building to ensure the best jamming effect.

How to operate the Pocket Mobile Phone Jammer

• At the very first time to use, if you want to use this device outside, please first use the attached switching power adaptor to charge the built-in rechargeable battery. It will take about seven hours to full charge the batter. If you install this device indoor for long term use, connect the switching power adaptor and you can use this device instantly.
• Before turn on the power switch, always check if the antennas are installed securely. If you turn on the power switch without the antennas installed on this device, it shall heavily damage this device. Never remove the antennas; otherwise you will void the warranty.
• Turn on the power switch, the green LED will light up and this device starts to emit interference signals. When turn off the power switch, the LED will put out and this device stops working.
• After the battery is fully charged, this device can be used for 2-3hrs.

About the Battery

• If the green LED does not light up after turn the power switch, it means the battery runs down. Connect the switching power adaptor to continue the jamming and to recharge the battery at the same time.
• It will take about 7 hours to full charge the battery under power off condition. If recharge under power on condition, it will takes about 36 hours to full charge the battery.
• In long term continuous use, it had better to remove the plug of switching power adaptor from this device once six months. Let this device use battery power for 1-2hrs, and then connect with switching power adaptor again. This will re-fresh the battery and keep the battery in good condition.
• If you are not going to use this device for a long time, please set the On/Off switch at ?Off? and check the battery power once three months.

Notice of Use the Pocket Mobile Phone Jammer:
When the battery runs down, if the switch is kept at ?on?, the battery will be over discharge and will damage the battery. Please set the on/off Switch at ?off? and connect the switching power adaptor to charge this unit for 7hrs. Battery will be over charged if you keep on charging it without using that will also damage battery. The producer accepts no liability for the damage caused by the over discharge or charge. Be sure to connect all the antennas firstly before the power supply is switch on. Please do not take off antennas when the machine is working.
Antennas shall be used vertical to the ground, working more efficiently.
Please don?t put the jammer in the water and fire to avoid using in the bad. Condition of over-wet, over-hot, high-voltage and high magnetism. After charging the cell phone jammer you will see a red LED light, however please recharge the Cell Phone Jammer two more times for full battery charging.
The jamming area is influenced by the location of the cell tower and the obstacles between cell tower & the cell phone jammer. It means that in normal condition if the distance is close between the cell tower & the cell phone jammer, it will have very less jamming area. Likewise, if there are obstacles & walls between the cell tower & the cell phone, the cell phone jammer will give less jamming area.
Any ruin and disrepair caused by incorrect operation and disassembly will exclude from the repair with free of charge.
