What do I do if I go to use one instrument, but I end up logging into a different one?

You need to contact us at: info@cns.fas.harvard.edu. For example, if you go to use one SEM, but end up logging into a different one by mistake, you will get hit with two charges: A no-show on one and the actual use on the other. Notifying us in a timely manner as requested will resolve this situation.
