The Thor VM2 uses an 8A time delay (slow blow), fuse that is externally accessible and user replaceable. The fuse is located on the back of the Quick Mount Smart Dock. The fuse is accessed by unscrewing the cap as indicated.
Should it need replacement, replace with same size, rating and type of fuse:
• Littelfuse 0215008.MXP
• Cooper Bussmann
• Bel Fuse 5HT
or equivalent.
Fuse has voltage on it even when power is off. Always disconnect input power before changing the fuse.
Power Management ModesThe Thor VM2 supports the standard Microsoft Windows CE power management modes: On (D0), Backlight Off (D1), Display Off (D2) and Suspend (D3).
On Mode (D0)When the Thor VM2 is attached to either vehicle power or an external power supply or is operating from the UPS battery and the power button is pressed, the Thor VM2 is in the On mode. In this mode, the keypad, touch screen and any attached peripherals such as a scanner function normally. The display remains on until the backlight timer (if enabled) expires.
User Idle / Backlight Off Mode (D1)Backlight is dimmed, but display is readable. The Thor VM2 transitions to this mode from On after the User Idle timeout period has passed without a primary even occurring.
System Idle / Display Off Mode (D2)Backlight and display are off. The status LED is solid green. The Thor VM2 transitions to this mode from User Idle after the System Idle timeout period has passed without a primary event occurring.
Suspend mode (D3)All devices that are not configured as wakeup events are powered off. The status LED is blinking green if external power is connected and off if external power is not connected. The Thor VM2 transitions to this mode from System Idle after the Suspend timeout period has passed without a primary event occurring.
By default power is turned off to the USB port when the Thor VM2 is in Suspend. The Thor VM2 can be configured to provide power to the USB port in Suspend using the Options (page
Additionally the power button can be used to enter or exit Suspend mode:
•If the Thor VM2 is On, pressing the power button immediately transitions the unit to Suspend.
•If the Thor VM2 is in Suspend mode, pressing the power button transitions the unit to On.
Shutdown / Off Mode (D4)The Thor VM2 shuts down when the Thor VM2 is operating on power and the UPS battery becomes critically low regardless of the current power management state. The Thor VM2 remains Off until external power is applied. The Thor VM2 may restart automatically when external power is applied or may require the user to press the Power button depending on installation and configuration.
The Thor VM2 transitions to Off mode from Suspend after the Shutdown timeout period has passed without a primary event occurring. If the Thor VM2 has external power applied or a sufficiently charged UPS battery the Thor VM2 may restart automatically or may require the user to press the Power button depending on installation and configuration.
A Real Time Clock (RTC) powered by an internal battery maintains the date and time while the Thor VM2 is off.
