Installing the in your Carson MM-300 MicroBrite Plus 120x LED Pocket Microscope is simple. First, locate the battery door on the side of the microscope and slide it open. Next, insert one AA battery into the compartment, making sure to match the positive (+) and negative (-) ends of the battery with the corresponding markings inside the compartment. Once the battery is correctly placed, securely close the battery door. Remember that a AA battery is required for the microscope's operation, and it is not included with the initial purchase.
