1 Safety instructions
If possible, read the entire operating manual - or at least these instructions and the chapter: "First
commissioning" - before putting the instrument into operation.
For your own safety, be sure to follow the basic precautions described below to avoid the risk of serious
injury or even fatal accidents, electric shocks, short circuits, damage, fire or other hazards.
These precautions include the following points, but they do not constitute a complete list or a final list.
Power supply
1. Use only the correct power supply required for the instrument.
2. Check the power supply with all connectors and the power cord at regular intervals for damage and
contamination.
3. Never place the power supply cables near strong heat sources such as heat eras or the like, do not
bend it excessively, do not place heavy objects on it and do not place it in places where you can step
on it, stumble over it and over it could roll.
4. Always pull the power cord on the plug and never on the cable from the socket to avoid damage.
5. If possible, do not connect the instrument to multiple sockets if other high-performance devices,
such as lighting systems, are already running over it.
6. During prolonged absence or thunderstorms, disconnect the power cord from the power outlet to
avoid damage caused by, for example, surges.
Installation site - Danger from water - Cleaning
Place the instrument in a stable place.
Avoid setting-up locations near strong heat sources or places that are subject to a sharp change in
temperature or humidity.
Ensure that the instrument on its back always has flawless ventilation.
Never place the instrument in close proximity to powerful radios such as fluorescent tubes,
televisions, mobile phones and others to avoid radiation that causes noise and degradation of sound
quality in your instrument can.
Do not place open flames (candles) or drinks on the instrument.
If electrically conductive objects or a liquid enter your instrument, immediately turn off
the instrument and unplug the power plug!
Do not return the instrument to operation until it has been inspected by a qualified WERSI customer service
technician. Never try to open the instrument yourself and make repairs or technical changes yourself.
Never put your instrument into operation immediately if you have just brought it from an unheated
environment (e.g. car) into a warm room. Wait until the instrument reaches room temperature to
avoid electrical damage from condensation and creep currents.
To clean your instrument, use only a soft cloth, at most slightly moistened, and not chemical
detergents or cleaning cloths.
