NOTE
Damage to USB stick and malfunction due to data loss!
Removing a USB stick while it is still in use and data are being transferred can render the USB stick un-
usable. Open files which can no longer be accessed because the USB stick has been removed can block
the device.
Therefore ensure that all operations are complete before removing the USB stick.
NOTE
Damage to property and malfunctions due to data loss!
The USB interface is protected against overloading (> 0.5 A). In the event of a short circuit during opera-
tion, the control unit may trigger a reset of the system.
Substantial property damage and damage to the USB device may ensue.
Before using a USB device, check carefully its power requirements.
NOTE
Failures and malfunctions will occur if direct connections are made to signal earth!
Use only USB devices that have no direct connection between signal earth and the housing.
The USB interface plug is designed to withstand 1,000 plugging and unplugging cycles.
