### `Rx.Observable.prototype.observeOn(scheduler)`
[Ⓢ](https://github.com/Reactive-Extensions/RxJS/blob/master/src/core/linq/observable/observeon.js "View in source")
 
Wraps the source sequence in order to run its observer callbacks on the specified scheduler.
 
This only invokes observer callbacks on a scheduler. In case the subscription and/or unsubscription actions have side-effects that require to be run on a scheduler, use subscribeOn.
 
#### Arguments
1. `scheduler` *(`Scheduler`)*:  Scheduler to notify observers on.
 
#### Returns
*(`Observable`)*: The source sequence whose observations happen on the specified scheduler.
 
#### Example
```js
/* Change from immediate scheduler to timeout */
var source = Rx.Observable.return(42, Rx.Scheduler.immediate)
    .observeOn(Rx.Scheduler.timeout);
 
var subscription = source.subscribe(
    function (x) {
        console.log('Next: ' + x);
    },
    function (err) {
        console.log('Error: ' + err);
    },
    function () {
        console.log('Completed');
    });
 
// => Next: 42
// => Completed
```
