Key Guard mode prevents buttons on the device from being inadvertently pressed. The hiptop enters this mode whenever you hold back for three seconds, select Jump--Menu--Key Guard, or after a user-configurable idle time (to configure, Jump--Menu--Settings--Key Guard & Security). Power-Saving mode turns off the screen to save power, but blinks the wheel periodically to remind you that the device is on and to indicate battery status (green means good, yellow means recharge soon, orange means recharge immediately). The only way the device enters this mode is after a user-configurable idle time in Key Guard mode. To change this time or disable this mode entirely, Jump--Menu--Settings--Battery & Backlight.
