This article will go over how to calibrate the touchscreen of your device, without the need to access the feature in the display's menu. This is useful whenever the screen seems unresponsive and accessing the menu is not possible. The following applies to Zen Tour, Goliath and Goliath HD devices.
Press down the following buttons until the calibration procedure appears on the display. Make sure to tap the points carefully. The procedure can always be retried in order to ensure maximum responsiveness.
Zen Tour - Gain and Antelope buttons
Goliath & Goliath HD - Mono and Antelope buttons
