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 breath stream, therefore minimising any
‘pop’ sounds.
Maintenance
As with any equipment which will be used in close
proximity to sensitive parts of the body, it is essential that the
ear pads, the headband and the microphone pop-shield are
kept clean. Use a damp cloth for cleaning the ear-pads and
headband using only gentle cleansing agents (such as washing-
up liquid). Take care not to allow any water drops into the
transducer elements and do not use any solvent cleaners. The
microphone pop-shield of the DT 280 / DT 290 / DT 290 V.11 /
DT 291 PV / DT 294 PV / DT 294 V.11 headsets can be easily
removed and washed in warm water. Please take care that the
pop-shield is completely dry when it is replaced. The ear-pads
can wear out due to effects of skin moisture, cosmetics and
mechanical strains while wearing the headphones. From time
to time you will need to replace the ear-pads:
1. Remove the ear-pad from the housing part.
2. Put the new ear-pad on the housing so that
the drop-in pins can lock in the corresponding holes.
3. Press the new ear-pad with the thumbs of both hands
to the housing until you hear a clear “click” noise.
Safety
When plugging in any of the DT 200 - series headsets to
the drive amplifier, we recommend that this is done before it is
fitted over the ears for use. This will give the technician the
chance to check that the volume levels are not too high. Please
remember that the user could well be a highly-paid presenter
and the consequences of damaging his / her ears may well prove
to be music to the ears of the lawyer! The very low levels of
distortion can make listening levels higher than is perceived
and we have to warn you that listening to programme or talk-
back at high levels for long periods can permanently damage
your hearing.
