If

are displayed for the ECG/RESP module, perform the
following actions:
6WHS
Make sure there is a trunk cable with lead set connected to the module. If not, con-
nect one.
6WHS
Make sure the ECG and RESP parameters are turned on. If they are not, turn them
on.
6WHS
Make sure the ECG (HR) and RESP numerics are turned on. If they are not, turn
them on.
6WHS
Make sure you don’t have more than one ECG/RESP module plugged into the
module racks you are using. If more than one ECG/RESP module is plugged in, the
supernumerary modules are ignored and should be removed.
6WHS
Check the connection on the module and the rack interface.
Unplug and re-plug the ECG/RESP module and check if the green LED on the
ECG/RESP module lights up after re-plugging. If it does not, proceed with the
following:
Put the ECG/RESP 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 ECG/RESP
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 ECG/RESP
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 ECG/RESP module into the new rack. If the
LED on the module does not light up, replace the rack interface card in the
function box.
