Important safety instructions
Overloading
Do not overload wall outlets and extension cables as this may result in fire and electric shock.
Replacement parts
When replacement parts are required, be sure the service technician uses replacement parts specified by Sennheiser or those having the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, or other hazards.
Danger due to high volumes
This product 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.
