Changing the Administrator Password
The default administrator user name and password of CTP18 and MeetingBar A20/A30 are "admin"
and "0000" respectively. Only the administrator can configure the network settings, log settings, re-pair
MeetingBar A20/A30 with CTP18, and modify the administrator password. For security reasons, we
recommend that you change the default administrator password as soon as possible.
