DLT-V72 Operating Instructions V2.50 Preliminary
15.2. Screen defroster (optional)
The following DLT-V72 devices are optionally available with a screen defroster.
−
DLT-V7210 D with resistive touchscreen
−
DLT-V7212 D with resistive touchscreen
Functional description
As soon as the internal temperature of the DLT-V72 device falls below 5°C, the screen defroster is
automatically activated and heats the front of the device. The front of the device thus thaws more quickly
when leaving cold stores, for example.
In terms of the ambient temperature, this means:
−
The defroster is typically active at an ambient temperature of 0°C to -10°C.
This depends on how quickly the ambient temperature changes or how quickly the DLT-V72 cools.
−
Analogously, the screen defroster is typically deactivated again when the ambient temperature
rises to +10°C to +20°C.
The screen defroster has a heat output of approx. 30 watts.
The screen defroster does not work when the DLT-V72 is running on battery power.
The screen defroster will switch off automatically if the internal device temperature is too high and
cannot be switched on manually using the keys.
Manual operation
The screen defroster can be manually activated and deactivated using the following key combination:
+
<SHIFT>
Important: The temp LED indicates whether the screen defroster is active or inactive, not the touch LED
above this key.
