GMH C 9.300 D Professional (Art-No.94-6150)
Application
The individual adaptable head‐bow can be adjusted easily to any head‐size. The microphone
boom is mounted on the left ear. The flexible gooseneck boom enables the ideal positioning
to any user.
Kindly note as follows:
Never overstretch or jigger the flexible gooseneck boom as it might loose its function.
‐
Before dropping off the headset make sure that the microphone amplifier is turned
‐
down to avoid feed‐back, as this could damage the microphone‐capsule.
Always protect the capsule against humidity.
‐
When replacing the capsule always make sure to avoid electrostatic dischargements
‐
as they could damage the electrical components.
Maintenance
For hygienic reasons the headphone should be cleaned from time to time with a soft and
damp cloth. Do not use solvent‐containing agents and avoid that humidity penetrates inside
the capsule or the electronics.
The pop‐filter can be rinsed with warm water. Before remounting take care that the filter is
completely dry.
As the ear pads are subject to natural wear they should be replaced regularly. Pull them
down carefully and replace with new ones. In case they are only slightly dirty, they can be
hand ‐washed in hand‐warm water added with some mild detergent. Carefully dry them only
at room temperature.
Safety
When connecting the GMH C 9.300 D Professional to the amplifier always check that the
volume control is on minimum. Adjust the volume control of the headphone to the required
level only after you have put it on.
Please consider that monitoring at high volumes over long periods can permanently damage
your hearing!
