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 770 PRO is a closed dynamic headphone and was
designed for critical music and sound monitoring in an
open environment. It has a bass reflex system to give
low-frequency response down to 5 Hz and is equalised
to the diffuse sound field. The weight of the diaphragm
and moving coil of this headphone is approx. 20%
compared to other current models. As a result, the
DT 770 PRO offers similar pulse characteristics as electro-
static headphones. The cushion systems and light weight
allow the DT 770 PRO to be used in complete comfort for
long periods.
APPLICATION
u
The DT 770 PRO is ideal for control and monitoring
purposes. .
u
Due to the movable yokes and the adjustable head-
band made of spring steel, it can be ideally adapted
to any head size.
u
The connecting cable is single-sided and fitted with
a 3-pole gold-plated mini jack plug (3.5 mm) and
screw-on gold-plated adapter for 1/4" jack sockets
(6.35 mm).
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
damage.
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.
