tric shock.

replacement parts specified by the manufacturer or those having the same char-
acteristics as the original part. Unauthorized substitutions may result in fire, elec-
tric shock, or other hazards.
Safety check

to perform safety checks to determine that the device is in safe operating order.
Danger of hearing damage due to high volumes
This is a professional system. Commercial use is subject to the rules and regula-
tions of the trade association responsible. Sennheiser, as the manufacturer, is
therefore obliged to expressly point out possible health risks arising from use.
This system 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 med-
icine. Higher volumes or longer durations can damage your hearing. At higher vol-
umes, 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:
y You can hear ringing or whistling sounds in your ears.
y You have the impression (even for a short time only) that you can no longer hear
high notes.

Intended use of the devices includes:
y using the device for professional purposes,
y having read these instructions, especially the chapter see „Important safety
instructions“ on page 5,
y using the device within the operating conditions and limitations described in
this instruction manual.

tions, or under operating conditions which differ from those described herein.
