Important safety instructions

Danger due to high volumes

This is a professional transmitter. 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 transmitter 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.

Intended use

Intended use of the SR 300 IEM transmitter includes:

• having read this instruction manual especially the chapter “Important safety instructions”,

• using the device within the operating conditions and limitations described in this

instruction manual.

“Improper use” means using the device other than as described in these instructions, or

under operating conditions which differ from those described herein.



CAUTION! 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.

왘Make sure that the ambient temperature within the rack does not exceed the permissible

temperature limit specified in the SR 300 IEM specifications.

왘Ensure sufficient ventilation; if necessary, provide additional ventilation.

왘Make sure that the mechanical loading of the rack is even.

왘When connecting to the power supply, observe the information indicated on the type

plate. Avoid circuit overloading. If necessary, provide overcurrent protection.

왘When rack mounting, 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.

Putting the transmitter into operation

왘Connect the antenna. You have the following options:

– You can connect the supplied rod antenna to the rear of the transmitter (see

page 8). In this case, insert the two blanking plugs into the holes of the blanking

plate (see diagram on page 9).

– You can use the AM 2 antenna front mount kit (optional accessory) and mount the rod

antenna to the blanking plate .

– You can use a remote antenna, if necessary in conjunction with the AC 3 antenna

combiner.

왘Slide the transmitter with the mounted blanking plate into the 19” rack.

왘Secure the rack mount “ear” and the blanking plate to the 19” rack.
