Installation instructions:

1. MP-3000 cellular signal shielding system can be directly installed on the wall or the ceiling.

2. Install the antenna (install the longer antenna at the left "LONGER" side, and the shorter antenna at the right "SHORT" side).

3. Turn on the power switch, the "IN USE" LED will become lit. One minute later, your mobile phone will display "No signal" or "No network".

Note: Do not turn on the power switch until the antenna is well installed, otherwise the system will be damaged.

4．The RF power of MP-3000 has been properly adjusted before shipment, it is no need to adjust any more. If you think it necessary to adjust the scope of mobile signals for blocking, you can adjust the potentiometer on the back of MP-3000. (For details, please refer to User's Manual).
