Radio Considerations

The TeleMyo 2400T radio system operates in the 2400 MHz ISM (Industrial, Scientific and Medical) radio
band reserved for use in most countries of the world. The radio transfers data digitally using the
IEEE802.11b standard (commonly referred to as WiFi). This is the same protocol used by many wireless
computer network systems. Other devices operating in this frequency band include computer networks,
microwave ovens, cordless phone sets and BlueTooth enabled devices.
Despite all this competing radio activity the TeleMyo 2400T System is able to discern its particular
information from all the surrounding radio traffic. Reliable transmission depends on good signal quality.
Signal quality will fall with extended distances between the transmitter and the PC card or TeleMyo 2400R
receiver. Obstructions (walls, metal structures, trees, etc.) between the transmitter and receiver will also
lower the signal quality.
As the signal quality decreases, the radio transmission is automatically modified to ensure reliable data
flow. This can mean either slowing down the rate of data delivery or re-transmitting any data that was
improperly received.
While the TeleMyo 2400T is quite immune to interference, it does transmit a deliberate radio signal that
could effect nearby sensitive equipment. Users should always be aware of this possibility. In a similar
manner, although the energy level of the radio is considered harmless to human beings, it is still prudent to
minimize exposure.
Finally, although available worldwide, each country places certain restrictions on the operation of radios in
the 2400 MHz ISM band. These restrictions include allowable transmitter power levels and broadcast
frequencies.
Never operate the TeleMyo 2400T within 1 meter of any critical medical
device.
When in use for extended periods of time, position the transmitter's
antenna away from any exposed parts of the body, especially the face or
eyes.
Do not operate the transmitter unless the antenna is connected. If the
antenna is not connected, the radio may be damaged.
Do not change or modify the transmitter antenna. This can increase the
output power level beyond what a certain country may allow.
Never change the radio channel setting without first contacting Noraxon.
Operation on unapproved radio frequencies is not allowed.
