Key Transitions

Key transitions are similar to background transitions. You can perform key and background transitions simultaneously.

Selecting Keys

Selecting a key allows you to configure the key type and select a source for that key.

To select a key:

›AUTO SEL, or CHR KEY — selects Key 1 and sets the key type.

›KEY 2 SEL — selects Key 2.

›KEY 3 SEL — selects Key 3 (KM-H 3000 only).

Note:

•If you select Key 1, you are selecting a key and key type simultaneously.
