You are advised to move the device to cooler
surroundings. If the device is switched on in
this condition, there is a risk that device
temperature will rise significantly over time as
a result of the waste heat generated and
become critical.
For handheld operation, you can generally
assume that all parts of the device surface are
below 43 °C and that the device can therefore
be held for at least 5 minutes without the risk
of injury/damage from heat.
Reducing the display brightness can improve
the situation as this generates less heat.

You are urgently advised to move the device
to cooler surroundings. If the device is
switched on in this condition, there is an
imminent risk of the device temperature rising
rapidly and significantly as a result of the
waste heat generated, and becoming critical.
For handheld operation, you can generally
assume that all parts of the device surface are
below 60 °C and that the device can therefore
be held for at least 1 minute without the risk of
injury/damage from heat.
Reducing the display brightness can improve
the situation as this generates less heat.

Power off the device immediately. The device
cannot immediately be switched on. If the
device is off, check whether the ambient
conditions are suitable for storage of the
device.
There is an immediate and serious risk of
injury from hot surfaces.

On the non-arctic HMI device, the "TEMP" LED comes on both when the temperature is too
low and when it is too high.
