12. Maintenance and Cleaning
Apart from an occasional battery change, the system components do not contain
any serviceable parts. Therefore, never open the system’s components.
Always unplug the power supply unit from the monitor before cleaning.
A clean, dry and soft cloth is sufficient to clean the outside of the monitor and the
remote control.
Clean the monitor and the remote control very carefully, otherwise you may scratch
them. Do not use any aggressive cleaning agents.
