Power Management Modes
On Mode (D0)
When the Thor VM3 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 VM3 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 VM3 transitions to this mode
from On after the User Idle timeout period has passed without a primary even occurring.
Warning: Improper replacement or repair could damage the battery,
cause overheating, risk of explosion, and result in injury. The
battery should be disposed of properly. The battery should not
be disassembled or crushed. The battery should not be heated
above 212 ˚F(100 ˚C) or incinerated. The battery must be
recycled or disposed of separately from household waste.
