Quick Defrost Application
The Omnii XT15f is a freezer capable hand-held computer that has integrated heaters that are designed to
improve the functionality and operation of the hand-held device in extreme cold environments. The Arctic
variant has two heaters; one for the display, and one for the scan window. The Chiller variant has only one
heater, which is located on the scan window. The "Quick Defrost" application is the nerve center of the
heater-related information. The
Settings
tab allows the user to configure the suspend time of the heating
system, as well as the scan window power setting. The
Heater Info
tab provides instantaneous heater infor-
mation for each individual heater and the overall heating system. For environmental specifications for this
computer, see “Hardware Specifications” on page F-4.
To ensure proper operation of the hand-held device in a freezer environment, the surface temperature is
managed by the heating system to prevent the formation of external/internal condensation on critical mod-
ules. The heating system consists of two heating elements; one for the display and one for the scan window.
Quick Defrost Settings
The individual heaters for the computer modules can be monitored, and the duration of time for them to
remain on during Suspend mode can be configured.

Suspend Threshold
The
Suspend Threshold
option allows you to maintain heat for a limited time when the computer enters
Suspend mode. Once the threshold is reached, the heater will stay off while the computer is in suspend.
•
To set the time, slide the trackbar to the desired time and click
OK
. Values range from 0 to 5 minutes.
Note: A longer suspend threshold will reduce your overall battery shift life.
