# Disable or deregister from Kaltura

*Applies to: Pearl-2, Pearl Mini, Pearl Nexus, Pearl Nano.*

You can disable CMS using the Admin panel and still select Pearl device as a resource using Kaltura MediaSpace. However, the events schedule won't synchronize on Pearl device and any events that are scheduled to start while CMS is disabled do not start on Pearl device. If CMS is re-enabled on Pearl device before the event is scheduled to end, that event will start automatically after the events schedule is refreshed on Pearl device.
Existing events that are already associated with the device do not lose their association when CMS is disabled. As soon as you re-enable Kaltura CMS on Pearl device, you can record and stream events as usual. CMS is disabled by default.
Deregistering removes Pearl device from Kaltura's list of resources and any existing events that were associated with that resource lose their association. You must select a new resource for those events using MediaSpace.
Content Management Systems (CMSs) can change channel settings automatically. After disabling CMS on Pearl device, check your channel settings or apply a configuration preset to restore your channel to known values.
**Important considerations**
- You cannot start ad hoc (manual) Kaltura events when CMS is disabled or when Pearl device has been deregistered.
- When CMS is disabled or Pearl device is deregistered, existing scheduled events that are associated with the device do not record or stream.
- If Pearl device is deregistered, existing events associated with that device lose the association. You must select a new resource for those events.
- Ensure the deregistered Pearl device entry in the list of encoder devices on Kaltura disappears before registering again if using the same device name.
- Do not disable CMS while an event is in progress.
After disabling or deregistering from Kaltura, the recording file size limit for the channels reset to 64 GB. Check to ensure this value does not exceed the maximum recording space allowed for the installed SD card and change the value to avoid unintentionally overwrite existing recordings.
**Disable Pearl device as a resource or deregister from Kaltura using the Admin panel**
