7.1 Maintenance
7.1.1 Cleaning the Housing
The housing of the 8585 is best cleaned with a damp cloth.
Do not use compressed air, a high-pressure cleaner or vacuum cleaner, as this can damage the surface.
Using a high-pressure cleaner poses the additional risk of water entering the device and damaging the elec-
tronics or display.
7.1.2 Touchscreen Cleaning
Use neutral detergent or isopropyl alcohol on a clean soft cloth to clean the panel surface.
Prevent using any kind of chemical solvent, acidic or alkali solution.
7.2 Troubleshooting
7.2.1 Data Transmission via LAN/Ethernet
If problems occur during data transmission over LAN/Ethernet (e.g. data is lost or not detected), the cause
of these problems may be a cable which is too long.
Depending on the cable layout and interference from the environment, it may be impossible to use the
cable length of 100 m given in the specification (IEEE 802.3 standard).
The solution here is the use of a shorter cable.
7.3 Common Mistakes in Usage
7.3.1 Power Supply
• Do not connect 8585 computers to an AC power supply.
• Observe correct voltage ranges.
7.3.2 Powering Up/Down
• Please note that the function of the 8585's [Power] key varies depending on how the device is
configured.
• Only disconnect the computer from the power supply after the computer has been properly shut down
and switched off. Otherwise file errors may occur on the storage device (in operating systems that
have no activated write protection filter).
7.3.3 Cable Cover
• The supplied cable cover for the external ports must be installed prior to using the 8585.
• In order to comply with protection class, please use the assembly kit from Psion.
7.3.4 Mounting/Installation
• Only use suitable mounting brackets and screws permitted by Psion.
• Ensure that ball-and-socket bases and fastening arms are securely attached.
• Follow the instructions carefully when attaching all outgoing cables to the strain relief rail.
• The WLAN antenna should not be used as a handle when turning the terminal.
• All fastening brackets and mounting parts supplied by Psion are only intended for use in the mounting
of terminals and peripheral devices and may not be used for other purposes.
