the USB cable from the computer if the headset is not to be used for an extended period 

of time.

Do not use alcohol, benzene, or thinner to clean the cabinet.

Sound from the headset may be interrupted depending on the communication 

conditions of the network.

Do not leave the system in a location near heat sources, radios or TV receivers, or a 

place subject to direct sunlight, excessive dust, moisture, rain or mechanical shock.

volume so high that it bothers people around you. There is a tendency to raise the volume 

when listening in noisy places. However, the volume should be kept at a level where you 

can respond when called, etc.
