Self timer is an automatic feature that provides a delay after you presses the shutter until the shutter actually opens, to allow you to take a self-portrait, to pose in a family group picture, or to reduce hand-shake. RNS:: TopCameraTimer adds this feature to the built-in Camera application on your Treo. After the installation, a new button becomes available in the Camera's interface. When you press the button, the timer starts to count down to finally take a picture. You may adjust the timer's delay and toggle tick sounds in the 'RNS:: TCT' panel of the system Prefs application. This product was created for Treo 650, Treo 680, Treo 700, and Treo 755p only. It will not work on other devices than Treo 650, Treo 680, Treo 700p, or Treo 755p.
