Maintenance

For cleaning metal surfaces, use a soft, damp cloth using only gentle
cleansing agents (such as washing-up liquid). Take care not to allow
any water drops into the microphone and do not use any solvent
cleaners.
Clean the PS 740 pop shield and the WS 740 wind shield in clear
water. All parts should be completely dry before they are used again.

Service

In the unlikely event of equipment failure, the product should be
returned to your beyerdynamic dealer. Failure to do so will invalidate
the guarantee.
