2.4. Connect the coolant tubes connectors to the PATHWAY front panel that fits the
Thermode you are using.
2.5. See Figure 107: CHEPS fMRI filter front view, for description of the fMRI Thermode
components:
2.5.1. Coolant tubes unit connectors (gray connectors).
2.5.2. fMRI CHEPS Thermode sensor connectors (pair of blue connectors).
2.5.3. fMRI Thermode main plug connector (black plug).
2.5.4. Hollow passage for COVAS and Response unit accessories. Note: This is not the
passage for the emergency button. You must transfer the emergency button to the
fMRI room through another passage.

2.6. Connect the printer cable to the laptop.
2.7. Connect the main power cord to the PATHWAY system.
3. Connect the required devices and accessories, as described in section 4.6.
4. Conduct a Grounding conductivity test: using a DVM measure resistance between the
ground pin of the power cord, fMRI filter body and ground pin of fMRI penetration panel.
The measured resistance must be less than 0.150 Ohm.
5. Conduct three phantom tests:
5.1. Conduct the test, when the Pathway is OFF,
5.2. Conduct the test, when the Pathway is ON and software is OFF,
5.3. Conduct the test, when the Pathway and software are ON and software test is running.
6. The installation is finished if all three tests are passed successfully.
