WHAT’S IN THE BOX

AMPLIFIER PLACEMENT

RECOMMENDATIONS

• Install the ampliﬁer indoors.

• Make sure there is an AC (mains) outlet nearby.

• To avoid interference, keep other wireless equipment 1 – 3 ft (0.3 – 0.9 m) away

from the ampliﬁer.

• For optimum performance, place the ampliﬁer in a well-ventilated area.

• Place the ampliﬁer on a shelf, or mount it on a rack or wall.

• When mounting on a rack, make sure the rack mount arrow and four tabs are

facing the front of the rack (see page 55).

• When mounting multiple ampliﬁers on a rack, use a separate rack mount for

each ampliﬁer.

• When mounting on a wall, make sure the wall mount arrow and four tabs are

facing up (see page 57).

CAUTIONS:

• Place the ampliﬁer in an area where the maximum ambient temperature is less than

104°F (40°C).

• Keep the back side of the ampliﬁer at least 3 – 6 in (7.62 – 15.24 cm) away from any

other surface. Do not block airﬂow from the back of the ampliﬁer.

• Do NOT place the ampliﬁer in a completely enclosed area. Doing so may result in

poor performance.
