Safety instructions
Intended use
The SilverCrest STL 1.5 A1 multi-function speaker is used in accordance with its intended purpose when it is used exclusively for playback of audio files stored on microSD cards or if it is connected to an audio source with the 3.5mm audio cable. Any other use is not as intended.
The manufacturer does not assume any liability if:
The multi-function speaker is not used as intended.
The multi-function speaker is damaged, incomplete or modified prior to connection and use.
This is an electronic entertainment device. It may only be used for private purposes, but not for industrial or commercial purposes.
General safety information
Keep electric devices away from children or persons with mental or physical limitations! Never let such persons use electric devices without supervision. They cannot always recognise possible hazards.
Small parts can be fatal if swallowed. Also note that there is a risk of suffocation if air passages are blocked by the plastic packaging.
If smoke is produced, or there are any unusual sounds or smells, turn the multi-function speaker off immediately. In these cases the device should not be used until it has been inspected by authorised service personnel.
Operational safety
Never use any adapter plugs or extension cables which are damaged or which do not comply with valid safety standards.
To disconnect a cable always hold the multi-function speaker and pull the plug, not the cable. Ensure that the cable is not kinked and does not cause an obstruction.
If the multi-function speaker is exposed to extreme temperature fluctuations, condensation can lead to the accumulation of moisture which can cause a short circuit. In this case wait until the multi-function speaker has reached ambient temperature before use.
Operating environment/Environmental conditions
Protect the multi-function speaker against moisture, vibration, dust, heat and direct sunlight. It could otherwise become damaged.
