COMPATIBILITY
The receiver and transmitter must be on the same UHF frequency to operate together. Because of the specialized equipment required to adjust these units properly, users cannot change the fre- quencies or make any internal adjustments.
If two or more R200 and/or other VHF/UHF wire- less systems are being used in the same location, proper frequency coordination is necessary to avoid interference. Frequency mixing and spacing must be factored along with local TV stations to determine if conflicts will result from a specific group. Contact your dealer or Electro-Voice for frequency-selection assistance if you are planning to add more wireless systems to be operated si- multaneously in the same location.
POTENTIAL SOURCES OF INTERFERENCE
There are many potential sources of interference for your wireless system. Any electronic compo-
nent 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 affect the performance of your wireless sys- tem. It is always best to place your receiver as far away from these devices as possible to minimize this potential source of problems.
BATTERY RECOMMENDATIONS
Fresh 9-volt alkaline batteries from a quality manufacturer will yield the best performance from R200 transmitters. 8.4-volt ni-cad batteries can be used but will yield much shorter operational time. When the transmitter switch is turned on, the bat- tery light will flash one time 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.
