5. Don’t put the antennas (outdoor and indoor) too close to each other. Recommended distance is 10-20 m. Be
sure to point them to the opposite directions to avoid the risks of malfunctions such as self-oscillation or
interference. It's also recommended that they are not placed in direct vision to each other (use metallic
obstacles, wall, ceiling, slab, etc).
6. Plug the power supply into the Signal Booster input (carefully, to avoid damaging the center pin) and then
into a wall outlet.
Note:
It is recommended to plug all AC power supplies for home electronics into a Surge Protector Power
Strip.
7. Switch the booster on only after having positioned the antennas correctly, according to the instructions
above.
8. Using multiple Signal Boosters in one installation could cause interference to the base station (except for the
In-Line Signal Boosters).
