11.6 Cold weather conditions
The Ranger HRC MS system is designed and manufactured to comply
with demanding requirements. The system can be used under the most
challenging weather conditions. In addition to protections such as seal
-
ing, bearings and encapsulation, there are also built-in heaters that pro-
tect the electronics and defrost the lens in low temperatures.
11.6.1 Heating
If the ambient temperature is below freezing point, built-in heaters will
automatically be started before the system is turned on. The heating of the
system takes several minutes – up to 30 minutes if the ambient tempe-
rature is very low. It is recommended to let the whole heating procedure
take its time, but if necessary the heating can be interrupted by pressing
the
PRK
button.
When the heaters are on, the heater indicator on the JCU is lit.
11.6.1.1 Defrosting
If the front lens of the IR camera needs more heating, at this time or later,
the defroster can be activated manually.
