-  * Although the `Timer` can be manually set, using `Reset` is the better way to default the initialization timer to the correct amount.
-  * An external script will be necessary to operate the actual initialization countdown.

-  * The `Timer` must be set (or reset) (or countdown) to 0 to be `Ready` and then it must be activated.
