What’s Included
The WVL package includes the following items:
• Wireless Voice Link Handset (1)
• Olympus ME52W Standalone Microphone (1)
• AAA Alkaline Batteries (2)
• Quick Start Guide (1)
How It Works
The WVL is a radio pair that operates in the 2.4 GHz unlicensed radio band. The handset communicates
wirelessly with the base station located inside the simulator. The base station converts the digitized
microphone stream from the handset and outputs it via the base station to the headphone and line out
jacks. The output projects through the head speakers inside the simulator.
To accommodate multiple WVL pairs in close proximity, each WVL is assigned two RF channels on
which to operate. The RF channels divide up the 2.400 – 2.4835 GHz spectrum in 80 single frequencies
to prevent the WVLs from interfering with each other.
Due to the nature of the unlicensed 2.4 GHz band, there may be other devices such as Wi-Fi, microwave
ovens or Bluetooth® radios operating in the 2.4 GHz band as well. Therefore, two channels are used to
transmit the audio stream redundantly to avoid interference. In case there is an interference in one
channel, the other can be used to extract the audio stream.
To operate correctly, both the handset and base station should be set to the same frequency using the
DIP switches located in the devices. If the interference is too high, the WVL firmware has the ability to
change channels automatically to avoid interruption. This process occurs simultaneously in both the
handset and the base station without the need for user intervention. The units revert back to the
original frequency set on the DIP switches when both devices are restarted using the power switch.
Recommendations for Use
To receive the best sound quality from the WVL, please note the following recommendations:
• Do not separate the WVL pair with more than two walls.
• Use channels 0 through 11 for the best sound quality.
• Use channels 12 through 31 if more than 12 simulators are present in one
area.
