B.1.7 Caution in Setting Volume Control
When adjusting either the Microphone Gain Level or the Headset
Speaker Volume, do not turn to maximum level from the start. You should
first try with a lower volume settings and slowly adjust to an appropriate
level. Be careful if you combine a high microphone gain level with a high
speaker volume, as this may result with a high-pitched feedback noise
(“squealing” sound). Such noise can cause severe damage to your hearing,
and prolonged usage under such settings will damage the headset and the
amplifier.
