Care and Maintenance
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 washing-up liquid to dampen the cloth. Never spray the
cleaning agent directly onto the touchscreen - spray it onto the cleaning
cloth instead. Never use aggressive solvents or abrasive cleaning agents.
Protective membrane
WARNING!
Protective membrane may not be used due to the potential for electrostatic
discharge.
