(ReadyNASOS-6.9.0-arm.zip) The administrator page has no menus, so nothing can be done from there. - Backup is not possible through the Administrator page - Configure NAS 102 and its features - Retrieve information from logs The NAS 102 must now be manually switched off with the (On / Off) button on the NAS.
