Please read this instruction manual carefully and completely before
using the products.
Make this instruction manual easily accessible to all users at all
times. Always include this instruction manual when passing the
products on to third parties.
Do not use the products in situations which require special attention (e.g. when performing skilled jobs).
Always keep the products dry and do not expose them to extreme
temperatures.
Use the products with care and set them up in a clean, dust-free
environment.
Varnish or furniture polish may degrade the feet of the transmitter,
which could stain your furniture. You should therefore place
the transmitter on a non-slip pad to avoid potential staining of
furniture.
Always maintain a distance of at least 3.94“ (10 cm) between the
ear cups and the cardiac pacemaker or implanted defibrillator since
the product generates permanent magnetic fields.
This stethoset receiver allows you to set higher volumes than
conventional headphones. This can cause hearing damage in
persons with healthy hearing and especially in children.
Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way, such
as power supply cord or plug is damaged, liquid has been spilled or
objects have fallen into the apparatus, when the apparatus has
been exposed to rain or moisture, does not operate normally, or has
been dropped.
WARNING: To reduce the risk of fire or electric shock, do not expose
the products to rain or moisture.
Use only the supplied mains unit.
Disconnect the mains connector from the wall socket
– to completely disconnect the products from the mains,
– during lightning storms or when unused for long periods of time.
Ensure that the mains unit is
– always readily operable and easily accessible,
– properly plugged into the wall socket,
– not covered or exposed to direct sunlight for longer periods of
time in order to prevent heat accumulation,
– only operated within the permissible temperature range (see
“Specifications” on page 32),
– not operated near heat sources.
Safety instructions
Intended use
Intended use includes
• having read this instruction manual, especially the chapter “Safety
instructions” on page 2,
• using the products within the operating conditions and limitations
described in this instruction manual.
“Improper use” means using the products other than as described in
this instruction manual, or under operating conditions which differ
from those described herein.
Safety instructions for the Lithium-Polymer rechargeable battery
The BA 300 is a Lithium-Polymer rechargeable battery. If abused or
misused, this rechargeable battery may be damaged. Please understand that Sennheiser does not accept liability for damage arising from

your specialist dealer.
When not using the
rechargeable battery for
extended periods of time,
charge it regularly (every
6 months for about 1 hour).
Do not short-circuit.
Only charge rechargeable
batteries at ambient
temperatures between
10°C/50°F and 40°C/104°F.
Do not mutilate or
dismantle.
Do not charge the rechargeable battery if the device is
obviously defective.
Store the devices/
rechargeable batteries in
a cool and dry place at
room temperature.

operation
Setting up the transmitter
왘
Choose a suitable place near your sound source (e.g. TV).
왘
Do not place the transmitter close to metal objects such
as shelf bars, reinforced concrete walls, etc. as this can
decrease the transmitter’s range.
It is not necessary that the transmitter and receiver are in
the same room, so you can move around freely in the home
or outside in the garden.
When the receiver leaves the range of the transmitter, it
produces warning signals and then automatically switches
off after 3 minutes.
One transmitter can be used to transmit to several
receivers on the same frequency.

Compression (settings 1 and 3)
Deterioration of the ability to hear quiet sounds as well as loud ones is
a typical symptom of old age. Compression compensates for these
volume differences by boosting the volume of quiet sounds and
reducing the volume of loud sounds if necessary.
Compression seems to put the speech in the foreground, making it
easier to understand.
Compression is self-regulating; once it has been activated, it is not
necessary to make any other settings.
Treble boost (settings 2 and 3)
Another typical age-related phenomenon is the deterioration of the
hearing with regard to high frequencies. However, high frequencies are
important for the intelligibility of speech.
The treble boost makes the speech clearer and easier to understand.
With the treble boost (settings 2 and 3), additional fine adjustment is
possible using the treble boost control G at the rear of the transmitter.

Additional technical information
왘 Use a screwdriver to turn the treble
boost control G to the left or right
until the sound can be heard very
well.
The position “0” corresponds to a
minimum boost, the position “MAX”
corresponds to a maximum boost, and
the control is factory-preset to the
medium position.
G
Function of the treble boost control
By means of the transmitter’s steplessly adjustable treble boost
control G, the audio signal is boosted as shown in the diagram.
The treble boost control G allows you to select one of the curves
shown in the diagram below.
