indicates a "check adaptor" alarm. A fast blinking red light indicates the adapter

needs to return to zero (see section 10.1.2).

Note: The adapter needs to be preheated for 2-3 minutes (until the red light

extinguishes) to prevent condensation on the optical analysis window from affecting

the measurement results.

10.2 Proper Connection

For the mainstream module, the adaptor should always be kept in the correct

position, as follows:

The mainstream ETCO2 module needs to be pre-heated before use. Preheating time

takes about 3 minutes, depending on the ambient temperature. For example, the

preheating time in a colder room will take about 3 minutes where as a warmer room

may take as little as 1 minute. The purpose of preheating is to prevent condensation

from building up in the adapter. When condensation occurs, the monitor will prompt

the "check adaptor" alarm. When a new probe is connected to the monitor, the red

light will always be on, which means the module is in a preheated state. When the

red light goes out, the module is preheated and no lights will be on. When the probe

is in a normal measurement state, the green light will turn on when exhalation is

detected and will turn off when inhalation is detected. If the module has a slow

flashing red light, it is in a "check adapter" state. The user should check to ensure the

adapter is connected properly and the optical analysis window is clear. If the module

has a fast flashing red light, it is indicating "return to zero". Disconnect the module

from the patient, ensure no respiratory gases are in the adapter, then disconnect and

reconnect the adapter to the module. The module will automatically return to zero

without entering the monitor set up software.

When the mainstream ETCO2 module is being used for a long period of time, it is

recommended to periodically check to whether the optical analysis window is

contaminated by respiratory secretions. If the optical analysis window is found to be

dirty, it is necessary to clean the adapter window or replace with a new adapter. If the
