When replacement parts are required, be sure the service technician has used replacement
parts specified by Sennheiser or those having the same characteristics as the original part.
Unauthorized substitutions may resul t in fire, electric shock, or other hazards.
Danger due to high volumes
This is a professional device. Commercial use is subject to the rules and regulations of the
trade association responsible. Sennheiser, as the manufacturer, is therefore obliged to
expressly point out possible health risks arising from use.
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.

Preparing the transmitter for use
You can set up the SR 2020 D transmitter on an even surface or
mount it into a 19“ rack.
Note:
Do not fit the rubber feet when rack mounting the transmitter.
Setting up the transmitter on an even surface
To ensure that the transmitter cannot slip on the surface on
which it is placed, four self-adhesive soft rubber feet are
supplied.
Risk of staining of furniture surfaces!
Some furniture surfaces have been treated with
varnish, polish or synthetics which might cause
stains when they come into contact with other
synthetics. Despite a thorough testing of the
synthetics used by us, we cannot rule out the
possibility of staining.
Do not place the transmitter on delicate
surfaces.
Ensure that the base of the transmitter is clean and free from
grease before mounting the rubber feet.

Rack-mounting
Risks when rack mounting the transmitter!
When installing the device in a closed or multi-rack
assembly, please consider that, during operation,
the ambient temperature, the mechanical loading
and the electrical potentials will be different from
those of devices which are not mounted into a rack:
The ambient temperature within the rack must
not exceed the temperature limit specified in
the specifications.
When installing the device in a rack, take good
care not to affect the ventilation required for
safe operation. If necessary, provide additional
ventilation.
Make sure the mechanical loading of the rack is
even to avoid a hazardous condition such as a
severely unbalanced rack.
When connecting the device to the mains,
observe the information indicated on the type
plate. Avoid circuit overloading. If necessary,
provide overcurrent protection.
When installing the device in a closed or multi-
rack assembly, please note that intrinsically
harmless leakage currents of the individual
mains units may accumulate, thereby
exceeding the allowable limit value. As a
remedy, ground the rack via an additional
ground connection.
