CAUTION: Damage through electrostatic discharge!
▶ Never touch a PCB if you are not wearing an earthed
wristband.
CAUTION: Equipment damage due to electrostatic
discharge!
▶ Never touch a PCB if you are not wearing an earthed
wristband.
CAUTION: Damage through electrostatic discharge!
▶ Never touch a PCB without an earthed wristband.
Temperature sensors TH6 and TH7 form a single unit and
must, therefore, be replaced together ( “Replacing
outside temperature sensor TH7”).
CAUTION: Equipment damage due to electrostatic
discharge!
▶ Never touch a PCB if you are not wearing an earthed
wristband.
Temperature sensors TH6 and TH7 are a single unit and
must be replaced at the same time ( “Removing
outside temperature sensor TH6”).
CAUTION: Equipment damage due to electrostatic
discharge!
▶ Never touch a PCB if you are not wearing an earthed
wristband.
