SAFETY INSTRUCTIONS
Risk of injury
u
We would like to point out that excessively
high volumes and long listening times may
cause hearing damage. Hearing defects
always constitute an irreversible impairment
of hearing ability. If you suffer from tinnitus,
do not use headphones or reduce the
volume.
u
According to regulations to protect
employees against damages caused by noise
and vibrations, please follow these
instructions:
85 dB SPL for max. 8 hours
88 dB SPL for max. 4 hours
91 dB SPL for max. 2 hours
94 dB SPL for max. 1 hour
97 dB SPL for max. 30 minutes
100 dB SPL for max. 15 minutes
u
When connecting the headphones, please
ensure that the volume is turned down to
minimum. Adjust the volume after putting
on the headphones.
Danger to life
u
Headphones drastically reduce perception
of external sounds. Using headphones in
road traffic can be potentially dangerous.
The user's hearing must not be impaired to
the extent that it causes road safety risks.
Please also make sure that you do not use
the headphones in traffic, especially within
an area of potentially dangerous machines
and tools.
u
Furthermore, avoid using headphones in
situations where hearing must not be
affected, especially when crossing a
railway crossing or at a construction site.
Liability / intended use
u
Do not use the product for any application which is
not described in this product information.
u
beyerdynamic is not liable for improper use of the
product and its accessories.
DESIGN FEATURES
The DT 990 PRO is an open dynamic headphone. The
weight of the diaphragm and moving coil of this
headphone is approx. 20% compared to other current
models. As a result, the DT 990 PRO offers similar pulse
characteristics as electrostatic headphones. The
cushion systems and light weight allow the DT 990 PRO
to be used in complete comfort for long periods.
APPLICATION
u
The transducers are fitted to adjustable yokes
which should be positioned to fully enclose the ear.
This will provide the optimum ear / speaker position
for accurate sound monitoring.
u
The coiled cord can be extended to a maximum of
3 m and is terminated with a high quality gold plated
mini-jack and a 1/4" stereo jack adapter.
u
Caution:
Connect the jack connector of the headphone
cable to a headphone socket only! If you connect
the headphones to any other jack socket, the head-
phones could be damaged.
MAINTENANCE
u
As with any equipment which will be used in close
proximity to sensitive areas of the body, it is essential
that the ear pads and headband are kept clean.
Use a damp cloth for cleaning using warm water
only taking care not to allow any water drops into
the ear cups or transducers.
u
If necessary, you can carefully remove the ear pads
and headband pad and clean them with mild soapy
water.
u
WARNING: Never use any solvent cleaning agents!
Furthermore, the pads must be completely dry
before they are attached to the headphone again.
u
WARNING: Never use a vacuum cleaner for cleaning
the headphones, as this may cause irreparable da-
mage.
u
Should it become necessary to replace the ear pads
or the headband pad, refer to "Replacement parts
and Accessories". You can easily do this yourself.
u
If other components have to be replaced, please
contact your local beyerdynamic representative.
