V.11-Version of DT 287/297:
Adjustment of the built-in
microphone pre-amplifier.
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 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:
