Important safety instructions

• Danger due to high volumes

This device is capable of producing sound pressure exceeding 85 dB(A). 85 dB(A) is the

sound pressure corresponding to the maximum permissible volume which is by law (in

some countries) allowed to affect your hearing for the duration of a working day. It is used

as a basis according to the specifications of industrial medicine. Higher volumes or longer

durations can damage your hearing. At higher volumes, the duration must be shortened in

order to prevent hearing damage. The following are sure signs that you have been

subjected to excessive noise for too long a time:

– You can hear ringing or whistling sounds in your ears.

– You have the impression (even for a short time only) that you can no longer hear high

notes.
