and operational controls. It contains the Upper PCA board which sends the control input
information to the base. The base contains and uses the Lower PCA board to execute
received operational commands. The Lower PCA returns status and error code information to
the Upper PCA for display and diagnostics.

The supported console models include the P10, P20, P30, P80, and P82 models.

All consoles provide user input (keypad functions), user display (LED display / user feedback),
automated control (heart rate program, interval program) and service software routines (tests,

The keypad functions can vary between different console models, however the basic functions
