Configuring and Using Hearing Assistance

The Hearing tab of the Universal Access pane enables you to have your Mac display an on-screen visual alert when it needs to get your attention (see Figure 9.5). To set this, open the tab and check the "Flash the screen when an alert sound occurs" check box. When your Mac plays the alert sound, it will also flash the screen. Click the Flash Screen button on the Hearing tab to see what the flash alert looks like.

Figure 9.5. If you prefer your Mac to flash the screen when it needs your attention, use this check box to make it so.
