module into the new rack. If the
LED on the module does not light up, replace the rack interface card in the
function box.
❏ If a "LQVWHDGRIDQXPHULF and one or more INOP messages are displayed for the

6WHS Perform a module self-test (See “Performing the tcpO2/tcpCO2 Module Self-Test”
on page 5-44). If the tcpO
2
test numeric reads exactly 60 mmHg (8.0 kPa) and the
tcpCO2 test numeric reads exactly 40 mmHg (5.3 kPa), proceed to the next step, if
not, replace the module.
6WHS Enter the tcpO

/tcpCO
2
Task Window by pressing the setup key on the tcpO

/
tcpCO
2
module. The Task Window displays messages dealing with the tcpO
