If

are displayed for the SpO2/Pleth module, perform the
following actions:
6WHS
Make sure there is a transducer connected to the module. If no transducer is con-
nected, connect one.
6WHS
Make sure the SpO2/Pleth parameter is turned on. Turn it on, if it is not.
6WHS
Make sure the SpO2/Pleth numeric is turned on. Turn it on, if it is not.
6WHS
Make sure you don’t have too many SpO2/Pleth module plugged into the module
racks you are using. If too many SpO2/Pleth modules are plugged in, you get two
status messages: “Too many modules of the same type connected” and “Currently
ignored module in rack position x.x”. The last message enables you to identify the
supernumerary module.
These modules are ignored and should be removed.
6WHS
Check the connection on the module and the rack interface.
Unplug and re-plug the SpO2/Pleth module and check if the green LED on the
SpO2/Pleth module lights up after re-plugging. If it does not, proceed with the
following:
Put the SpO2/Pleth module into another slot and check the LED once again. If
it lights up now, the connector for the previous slot is faulty and the rack needs
to be replaced. If it does not, proceed with the following:

Replace the cable from the Satellite Rack to the function box. Again unplug
and re-plug the SpO2/Pleth
module and check if the LED lights up. If it does
not, proceed with the following:
Plug any other (not faulty) module into the same slot and check if the LED
lights up. If the LED of the alternative module lights up, the SpO2/Pleth
module is defect and has to be replaced. If it does not, either the rack or the
rack interface card is defect. Proceed with the following:
Replace the rack and plug in the SpO2/Pleth module into the new rack. If the
LED on the module does not light up, replace the rack interface card in the
function box.
