About channel locking
A channel can be either locked or unlocked. A locked channel is read-only and cannot be modified. An unlocked channel is writable and you can make changes to it, as necessary.
In the table under Image Channel Information, in the Locking row, the state of the channel locking is displayed. You can switch between the Write Locked and Not Locked states by clicking the available button in the row.
