Care and cleaning instructions
• Never spray the phone with liquids as the penetrating fluids can lead to mal-
functions or may damage the device.
• Clean the phone with a soft and slightly damp cloth.
• Do not use substances such as alcohol, chemicals, household cleaners or sol-
vents, as these substances can lead to surface damage or cause the coating
