Thank you for viewing! Power-on, software loading, basic operation, and sound confirmation have been tested. - The POWER button is difficult to use when turning off the power. - There is some blue corrosion on the battery compartment. Please understand and consider purchasing. Batteries are not included. Please check the condition in the images. If you would like to see other areas, I will try my best to accommodate your request, so please feel free to ask. I have other items for sale as well. Please take a look! I offer discounts for combined purchases, so please consider it.
