Troubleshooting

This appliance has delicate electronic components. This
means that if it is placed near an object that transmits radio
signals, it could cause interference. If interference occurs,
move such objects away from it.
Electrostatic discharge could lead to functional errors. If
such functional errors occur, remove the battery briefly and
replace it again (see fig. A).
Cleaning and storage
Only use a dry and fluff-free cloth for cleaning.
