Telemetered characteristic monitor system and method of using the same

An external telemetered characteristic monitor transmitter device for use in a system with a remotely located characteristic monitor and a sensor producing a signal indicative of a characteristic of a user, the transmitter device comprising:

• a housing;
• a sensor connector coupled to the housing and that is connectable to the sensor outside a body of the user to receive the signal from the sensor;
• a processor within the housing coupled to the sensor connector to process the signal from the sensor for delivery to the remotely located characteristic monitor;
• and
• a transmitter coupled to the processor for wirelessly transmitting the processed signals to the remotely located characteristic monitor worn on a body of the user and concealable within clothing, wherein the remotely located characteristic monitor utilizes the received processed signals to determine a display a characteristic reading of the user, wherein the transmitter device has a unique ID code and the transmitter transmits the processed signals to the remotely located characteristic monitor in pseudo-randomly selected time windows based on the unique ID code of the transmitter such that the transmitter is synchronized with the remotely located characteristic monitor.
