Sony MZ-N10 NetMD MiniDisc Recorder

Sony MZ-N10 MiniDisc player/recorder (grey). Quantity 1. Used.
* Player/recorder only. No other items, batteries, or accessories are included in the sale *

Summary:
Tested and functional. Almost perfect cosmetic condition. However, the built-in battery only holds enough charge for approximately 160 minutes of playback.
Also, for full transparency, while an inline remote control is not included in the sale, the display of the inline remote control used during testing was erratic and would sometimes display as expected and sometimes not display at all.
As such, we did most of the testing with earphones connected directly to the device.
** Device is shipped with the Built-In Battery switch set to OFF. This is to prevent the device being accidentally activated during shipping, and to preserve the battery. It will need to be set to ON before the device can be used **
*** This model requires a dedicated battery charging stand (BCA-WM21U) and power supply, or external AA battery pack EBP-N10 and power supply, to charge the built-in lithium-ion battery ***
