I purchased this item when it was first released and stored it at home for a long time after using it to some extent. I am selling it to declutter. It is an old item, approximately 25 years old, so there is some color fading and fine scratches on the LCD screen, etc. Also, there is no outer box or instruction manual. It might work if you replace the batteries with new ones, but I have not confirmed its operation. (I do not plan to check the operation myself, as I might damage the screws, etc. Please understand.) Please purchase only if you understand and accept that this is a junk item and that it may not work. Thank you.
