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. 
 

 

 
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. 
 

 
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.
