// Descripton:
// This example shows you how the initscreen or standbyscreen
// works. The initscreen is a hidden menu element (example 004)
// witch it is not displayed in menu. The initscreen is called
// when no action or trigger is set after ...cfg_initscreen_time
// milliseconds. When a other menu function is active, this function
// is stoped stable before initscreen function is started.
