I will include a printout if needed. (Please let me know in the transaction message after purchase if you need the manual.) ☆ I do not have an environment to check the functionality at the time of listing, so the operation is unconfirmed. * As shown in the photo, power has been confirmed. ☆ Please understand that this is a used item before purchasing. ☆ The coaxial cable was purchased separately for my home. (If you do not need it, please let me know in the transaction message after purchase that you do not need the cable.) ☆ Cancellations and returns after purchase are not accepted. Thank you for viewing.
