Preface
The purpose of this manual is to support the user during the installation, application, and modification of the
hardware/software described in the following sections. The processes are explained from various technical aspects to
simplify the individual steps.
In case of problems, it is helpful to try to identify the error in a reproducible way, and to compare the settings of all DIP
switches, jumpers, and connector pin assignments, as well as all parameter settings (software), etc., with the
specifications in this manual, before you call us.
The product you purchased is versatile and complex, and even a small oversight can affect overall performance.
Although the information in this document has been carefully reviewed, ROTEC does not warrant it to be free of errors or
omissions. In this case, we apologize and would greatly appreciate correction proposals.
ROTECreserves the right to make any changes to the hardware or software to improve functionality or simply operation.
These changes will not be documented in all instances.
No part of this manual may be reproduced, translated into other languages, or stored in data or word processing systems
without the express written permission of ROTEC.

2. Important Safety Information
This section contains:
Important safety information
Battery information
This display has been tested for conformance to safety regulations and requirements, and has been
certified for international use. Like any electronic device, however, the display should be used with
care. To protect yourself from possible injury and to minimize the risk of damage to the display, read
and follow these safety instructions.
General Guidelines
Read all of these instructions.
Save these instructions for later use.
Follow all warnings and instructions marked on the display.
Except as explained elsewhere in this manual, do not attempt to service the display yourself.
Opening or removing covers might expose you to dangerous voltage points or other risks.
Refer all servicing in marked compartments to service personnel.
If for any reason the cabinet cover needs to be removed, then the instructions given in this
manual must be closely followed.
Installation Restrictions
Do not use the opened display near water.
Do not place the display on an unstable cart, stand, or table. The display might fall and be
seriously damaged.
Do not block or cover the ventilation slots on the cover or cabinet of the display. Air must be
allowed to circulate through these slots in order to ensure that the display operates properly
and does not overheat.
Install the display near an electrical outlet for ease of access. Use the plug on the power cord
as the power disconnect device for the display. When your display is switched off, be aware
that it still carries full line voltage, and consumes some electrical energy. To completely
remove all voltages from the display and the auxiliary outlet, you must unplug the power cable
from the wall outlet.
Do not place the display near or over a radiator or heat register or in direct sunlight. Place the
display in a small enclosure only if providing proper ventilation.
To prevent fire, never place any type of candle or flames on the top or near the display.
Do not permit anything to rest on the power cord. Do not locate the display where people can
walk on its power cord.
