Electro-Voice R300 User Manual page 21

keyboards, digital lighting controllers, CD and DVD players, and computers, all emit RF energy that can
adversely affect the performance of your wireless system. It is always best to place the receiver as far
away as possible from these devices to minimize potential problems.
Analog and Digital Television stations can also interfere with your wireless system. The R300 is
designed to operate over 16MHz of RF bandwidth, which covers 3 US TV stations. If two of the three
stations are used in your area, it will severely limit the number of systems that will operate together and
you should be using a different band.
Battery Recommendations
Fresh AA alkaline batteries from a quality manufacturer will yield the best performance from your R300
transmitters. If sound quality degrades during use, it may be the result of a weakening battery.
Receiver and Antenna Placement
Do not place the receiver near a large metal object or surface. Locate the receiver as close as possible
to the area where the transmitter will be used. Ideally, position the receiver/antennas are within sight of
the transmitter. When using multiple systems, do not allow antennas to cross or touch each other.
Transmitter and Antenna Distance
Keep all transmitters at least 3 meters (10ft) away from the receivers and antennas for best operation.
If possible, mount the receive antennas 3 meters (10ft) above the stage so transmitters can not come
too close.
