4 Guidelines/Recommendations for best performance
Compatibility
The receiver and transmitter must be set to the same channel
to operate together.
Using Multiple Wireless Systems
If two or more N/DYM Wireless and/or other VHF/UHF wire-
less systems are being used in the same location, proper fre-
quency coordination is necessary to avoid interference. The
following N/DYM System channels will work together:
Channels 0,1,2,3, & 4 or Channel 5,6,7,8, & 9
Contact your dealer or Electro-Voice for assistance, if you are
planning to add more wireless systems to be operated simul-
taneously in the same location.
Potential Sources of Interference
There are many potential sources of interference for your
wireless system. Any electronic product that contains digital
circuitry including digital signal processors (reverb/multi-
effects units), electronic keyboards, digital lighting controllers,
CD players and computers, all emit RF energy that can
adversely affect the performance of your wireless system. It
is always best to place your receiver as far away from these
devices as possible to minimize this potential source of prob-
lems.
Battery Recommendations
Fresh 9-volt alkaline batteries from a quality
manufacturer will yield the best performance from
your N/DYM transmitters. Rechargeable 8.4-volt
Ni-cad batteries can be used, but will yield much shorter
operational time.
When the transmitter switch is turned on, the red
battery light will flash once if the battery is good. If
the light does not flash or stays lit continuously, the battery is
weak or dead. If the light comes on during use, the battery is
weakening and should be replaced as soon as possible.
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 user will be working. Ideally, position the
receiver so that the transmitter is within site of the receiver.
When using multiple systems, do not allow antennas to cross
or touch each other.
Multiple System Setup & ClearScan
TM
ClearScan
TM
is most useful for finding operating fre-
quencies for situations where no more than 2 systems
will be used simultaneously. When setting up more
than 2 systems, use ClearScan
TM
to choose the first
channel of operation. Set up subsequent systems fol-
lowing the channel groupings listed above in the “Using
Mulitple Wireless Systems” section.
