Adding CO2 To MTR-1

1. Unplug your MTR-1 from power and remove the back (board shown is msr-1)

2. Remove the board from the case and orient it like the image below. You will see a black connector on the bottom right, with an 'X' at its lower right corner.

3. Orient the CO2 module so that the white 'X' is on the lower right and the gold dot on the upper left, as shown in the image below. 

4. Align the connector on the back of the CO2 module with the connector on the MTR-1. Once aligned, push down so the CO2 module fully seats itself

5. Put your MTR-1 back in the case and slide the back cover on. Please refer to our CO2 calibration guide to calibrate the CO2 module.
