Hello,
Your Tocky is in protection mode. Protection mode begins only when the battery is approaching a low state at the same time when Tocky endures a drop to the floor. During Tocky's drop to the floor, a big voltage drop can occur which can damage some internal software. In order to prevent any damage to the software, we created protection mode. In protection mode, the USB drive will not be recognized, and no sound will be heard (or read from the USB flash drive), and all recording will be disabled. However, your product will continue to roll, and will continue to show the time display.
In order to take Tocky out of protection mode, you will need to 1. Remove the batteries for 5 minutes. 2. Then, install brand new batteries. 3. Press the toggle for 3 sec to reset the product. While AAA Alkaline batteries can be used, we highly recommend Lithium batteries to prolong Tocky's battery life.
