Changing the Administrator Password
The default administrator user name and password of MeetingBar A20 and CTP18 are "admin" and "0000”
respectively. Only the administrator can configure the network settings, log settings, re-pair the MeetingBar
A20 with CTP18, and modify the administrator password. For security reasons, we recommend that you
change the default administrator password as soon as possible.
About this task
Note: If the system has enabled the lock settings feature, you need to enter the room password
before entering the system settings.
Attention: If you change the administrator password after pairing CTP18 and MeetingBar A20,
the password takes effect to both end. If you change the administrator password on MeetingBar
A20 or CTP18 before pairing, the password of CTP18 will be synchronized with the password of
MeetingBar A20 after pairing.

1. On the idle screen, tap Settings > General > System Settings > Admin Password.
2. Enter the administrator password (default: 0000) and tap Enter.
3. Enter the Old Password, the New Password, the Confirm Password, and save the change.
