8.1 Cleaning the touchscreen
Clean the unit's touchscreen at regular intervals. Use a damp cloth to do this.
NOTICE
Make sure the unit is switched off before cleaning it. This prevents you from
accidentally triggering functions when you touch the touchscreen.
Cleaning agents
Only use water and washing­up liquid to dampen the cloth. Never spray the cleaning agent
directly onto the touchscreen – spray it onto the cleaning cloth instead. Never use aggress­
ive solvents or abrasive cleaning agents.
