To configure the touchpanel, it may be necessary to access a series of setup screens
prior to viewing run-time screens that are loaded into the touchpanel for normal
operation. The Opening Screen, shown below, appears when a finger is held to the
touchscreen for approximately three seconds as power is applied. This screen
indicates that you are in "setup mode" and can proceed to configure the touchpanel.

and Settings Menu, shown after this paragraph. All resources to configure the
touchpanel are available from this menu.

The Preferences and Settings Menu displays five buttons: Calibration, Preferences,
Power Management, Advanced Settings, and Return. The Return button saves all
of the setup information to EEPROM and displays the main page that has been
programmed into your system.

Calibration of the touchscreen is required if the active touch area of a button does
not coincide with the button's image. Select the Calibration button to initiate
"calibration mode". The touchpanel prompts you with a message, "Touch Upper
Left Corner". Touch the corner of the screen; be as accurate as possible. Another
message, "Touch Lower Right Corner", appears. Perform the operation to complete
calibration and return to the Opening Screen.
If the Calibration button from the Preferences and Settings Menu cannot be reached,
complete the following steps.
1. Remove power (ST-BTP, ST-DS, and/or external AC power pack).
2. Reapply power while holding a finger to the touchscreen for at least
three seconds. During this short period, the words "SETUP MODE"
