OLYMPUS Linear PCM Recorder LS-100 Easy-to-understand button operation, I used it for work, but I haven't had a chance to use it lately, so I've been storing it. Only the main unit, batteries, and the included case are included, as shown in the photos. The battery (LI-50B) can be replaced when it runs out. USB cable and SD card are not included, so please use your own. I think the condition is good. Please consider if you understand that this is a used item. If you have any concerns, please feel free to ask. Immediate purchase is welcome. Thank you very much.
