1.2 RR420 (with integrated interface, behind display)
Important: the plastic case manufactured by 3D printing does not withstand the temperature
that can be found in a closed car, under a windshield, in the summer sun. Therefore, if your
car must stay parked in the sun, we advise you:
- remove the RR420 from the vehicle or place it in a cooler place (trunk ...),
- if this is not possible, turn off the RR420 and use a solar ray reflector (metallized accordion
placed under or better on the windshield) and leave the windows open,
- in last resort, turn off the RR420, place a white cloth on the RR420 and leave the windows
open,
- do not leave the cloth on the RR420 during use.
