jquery ui map no geolocation default position

Question

I was wondering how to set the position of the map if there is no available geolocation or if it is disabled in the browser.

Find an example here : http://jquery-ui-map.googlecode.com/svn/trunk/demos/jquery-google-maps-geolocation.html/

                $('#map_canvas').gmap({ 'disableDefaultUI':true, 'callback': function() {
                    var self = this;
                    self.getCurrentPosition(function(position, status) {
                        if ( status === 'OK' ) {
                            self.set('clientPosition', new google.maps.LatLng(position.coords.latitude, position.coords.longitude));
                            self.addMarker({'position': self.get('clientPosition'), 'bounds': true});
                            self.addShape('Circle', { 'strokeWeight': 0, 'fillColor': "#008595", 'fillOpacity': 0.25, 'center': self.get('clientPosition'), 'radius': 15, clickable: false });                                                              self.option('zoom' ,8);
                        }
                    });   
                }});
            }).load();
        });
    </script>
