Beyerdynamic DT 109 - Manual (Page 13)

The microphone should be positioned to the side of the mouth,
about 20 - 30 mm forward. This will keep it within the direct
sound path, but out of the breath stream, therefore minimising
any ‘pop’ sounds.
Important
Please note that there have been two versions of ear cup
connecting cables used during production. The older DT 100
models have a cable with screw terminal contacts whereas later
versions have soldered connections. Please make sure the
correct cable version is requested when ordering.
Maintenance
To keep the headband and earpads clean use a damp
cloth with a gentle cleansing agent (such as washing-up liquid).
Make sure not to allow any water to enter the transducer
elements. Do not use any solvent cleaners.
The microphone pop-shield of the DT 108/109 headset can be
easily removed and washed in warm water. Please take care
that the pop-shield is completely dry before it is replaced.
The fully modular design of the DT 100/102 and the DT 108/109
allows field replacement servicing without the need for specialist
tools. The order numbers of the spare parts are listed under
“Spares”.
In the unlikely event of equipment failure, the product should
be returned to your beyerdynamic dealer.
Safety
We strongly recommend that the headphone or headset
is plugged into the drive amplifier before you put them on. This
will give the technician the chance to check that the volume
levels are not too high.
Be aware that the very low levels of distortion can make
listening levels higher than is perceived. Please take into
consideration, that too high level hearing may lead, after
considerable time, to irrevocable hearing damage.
