+The Elyra microscope has only one switch that needs to be turned on. The first one is the Main Switch, which is a turn knob. Do not turn any other switches on/off. Next, you will need to switch on the computer under the table. If at any point during your experiment a loud peeping noise goes off, check 1. the CO2 sensor and 2. the cooling system of the Elyra and [refill the cooling liquid](Maintenance/Elyra 7) if necessary.
