SETUP AND SAFETY
-
Please note the following instructions:
-
The hi-fi system is designed for the playback of audio signals. All other uses are expressly prohibited.
-
If you want to set up the hi-fi system on wall shelves or in cupboards, please ensure that it is adequately ventilated. There must be at least 10 cm of space at the side, above and behind the hi-fi system.
-
Do not cover the hi-fi system with newspapers, table cloths, curtains, etc.
-
When setting up the hi-fi system, remember that furniture is often coated with various types of varnish and plastic, which often contain chemical additives. These additives may cause corrosion to the feet of the unit. This may leave stains on the surface of the furniture which can be difficult or impossible to remove.
-
If the hi-fi system is exposed to sudden changes in temperature, for example when taken from the cold into a warm room, wait at least two hours before using it.
-
The hi-fi system is designed for use in dry rooms. If you do use it outdoors, make sure it is protected from moisture such as dripping or splashing water.
-
Only use the hi-fi system in a moderate climate.
-
Do not place the hi-fi system close to heating units or in direct sunlight, as this will impair cooling.
-
Do not place any vessels containing liquids, such as vases, on the hi-fi system.
-
Do not insert any foreign objects in the CD compartment.
-
Do not place any objects such as burning candles on the hi-fi system.
-
If malfunctions occur due to brief mains overloads or static electricity charges, reset the device. To do this, pull out the power plug and connect it again after a few seconds.
-
Do not open the hi-fi system casing under any circumstances. Warranty claims are excluded for damage resulting from improper handling.
-
Attention should be drawn to the environmental aspects of battery disposal.
DO NOT INGEST THE BATTERY, CHEMICAL BURN HAZARD. -
Thunderstorms are a danger to all electrical devices. Even if the hi-fi system is switched off, it can be damaged by a lightning strike to the mains. Always remove the power plug during a thunderstorm.
-
Do not expose the battery to extreme heat, such as example sunlight, radiators, fire, etc.
-
The remote control contains a battery (AAA,1.5V). Please always keep the remote control and the battery (AAA,1.5V) out of reach of children.
-
If the battery (AAA,1.5V) is accidentally swallowed, it can lead to burns and even death within two hours. You should therefore see a doctor immediately.
-
Keep new and used batteries out of reach of children. If the battery compartment cannot be closed safely, do not continue to use the device and keep it out of reach of children.
-
CAUTION: Danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type.
-
Prolonged listening with the headphones at loud volumes can damage your hearing.
-
The MAINS plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable.
This lightning flash with an arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of non-insulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock.
WARNING: To reduce the risk of electric shock, do not remove cover (or
back) as there are no user-serviceable parts inside. Refer servicing to
qualified personnel.
