3.9 Uploading Data In A Docking Station
The Combo Docking and Quad Docking peripherals allow your hand-held to link to an
Ethernet network. They are typically used to upload transaction data to a server computer
when a radio link is not available. When a 7545 is properly inserted in a docking station, a
dock icon is displayed in the taskbar at the bottom of the unit screen. The hand-held also
detects the presence of the Ethernet network. Review the documentation provided with the
user application installed in your 7545 before preforming data uploads.
3.10 General Maintenance
3.10.1 Caring For The Touchscreen
The touchscreen is covered with a thin, flexible polyester plastic sheet with a conductive
coating on the inside. The polyester can be permanently damaged by harsh chemicals and is
susceptible to abrasions and scratches. Using sharp objects on the touchscreen can scratch or
cut the plastic, or crack the internal conductive coating. The chemicals listed below must not
come into contact with the touchscreen:
• mustard, ketchup
• sodium hydroxide,
• concentrated caustic solutions,
• benzyl alcohol, and
• concentrated acids.
If the touchscreen is used in harsh environments, consider applying a disposable screen pro-
tector (P/N HU6110). These covers reduce the clarity of the display slightly but will
dramatically extend the useful life of the touchscreen. When they become scratched and
abraded, they are easily removed and replaced.
3.10.2 Cleaning The 7545
• Use only mild detergent or soapy water to clean the hand-held unit.
Important: Do not immerse the unit in water. Dampen a soft cloth with mild detergent
to wipe the unit clean.
To prevent damage to the touchscreen, use only the stylus (pen) supplied
with your 7545.
