• Only remove new electronic components from the ESD packaging (tinted plastic bag) after putting on
the wrist grounding strap.
• Do not walk around with electronic components in your hand if they are not in ESD packaging.
Access to exchangeable device components
You can access the storage media (1), the fan cartridges (2) and the battery (3) via the rear side of the panel
PC. The components are located on the top of the connection block under covers (see Fig. 26). Depending
on the selected display size of your device, the storage media and battery are either located together under
one cover (A) or under separate covers (B). The procedure for replacing the components is the same
regardless of the arrangement on the device (see upcoming chapters).
