1.3. Intended use
The switching decoder is intended for use in model construction, especially in model railway
layouts, according to the specifications in the manual. Any other use is not in accordance with
the intended use and will result in the loss of the warranty claim. Intended use also includes
reading, understanding and following all parts of the instructions. The switching decoder is not
intended to be used by children under the age of 14.
1.4. Safety instructions
Note:
!
The switching decoder contains integrated circuits (ICs). These are sensitive to electrostatic
charging. Therefore, do not touch these components until you have "discharged" yourself.
For this purpose, e.g. a grip on a radiator is sufficient.
Improper use and non-observance of the instructions can lead to incalculable hazards. Prevent
these dangers by carrying out the following measures:
Only use the switching decoder in closed, clean and dry rooms. Avoid moisture and splash
water in the environment. After condensation has formed, wait two hours for
acclimatisation before use.
Disconnect the decoder from the power supply before carrying out wiring work.
Supply the decoder only with extra-low voltage as specified in the technical data. Use only
tested and approved transformers.
Only plug the mains plugs of transformers into properly installed and fused earthed sockets.
When making electrical connections, ensure that the cable cross-section is sufficient.
Heating of the decoder during operation is normal and harmless.
Do not expose the decoder to high ambient temperatures or direct sunlight. Observe the
information on the maximum operating temperature in the technical data.
Regularly check the operational safety of the decoder, e.g. for damage to the connection
cables.
If you notice damage or if malfunctions occur, disconnect the connection to the power
supply immediately. Send the decoder in for inspection.
