5 Care
Before cleaning, switch off the power supply. A soft cloth moistened with a mild
cleaning agent can be used for cleaning the housing. For cleaning the screen it is
better to use a soft paper towel moistened with a mild household cleaning agent. For
cleaning the surface do not apply the cleaning liquid directly but use a moistened
paper towel. Please avoid getting liquid into the housing.
6 Troubleshooting
6.1 General
Points
Attention:
The Preh Touch / Screen Commander does not contain any electronic components
that can be replaced or repaired by the user. Consequently you should not try to do
your own repair work. Moreover, you would lose all warranty claims for this product.
Activating the touch sensor surface must not be done with a sharp object, such as
credit card, long finger nails, ring, etc. Sharp or pointed objects will cause damage to
the touch sensor and are not covered under warranty
If the Touch/Screen Commander must be returned for service, it must be packed in
it's original packing material. If this is not done, the sender will be made responsible
for possible transport damage.
6.2 Diagnostic
Program
The diagnostic program COMDUMP is located in the path D:\TOUCH\MONTEST. It
is started in DOS mode or command prompt whereby the COM connection must be
stated; the baud rate is optional.
COMDUMP <number of COM port 1 or 2> [baudrate]
COMDUMP will then show you the data coming from touchscreen to COM port in
hexadecimal data on the screen. If you now contact the touch sensor the sent data
should be seen on the display.
