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.
