temperature (more than 60°C) or high humidity (more than
80%). Never leave the microphone in a car with its door closed
(particularly in summer) or near any source of heat.
• The microphone is exclusively used for measurement of sound
field. Do not use it for vocal use as it causes a large shock noise
when the power switch is set to ON and OFF.
• Do not turn or loosen the head cap on the tip of the microphone
as it affects the performance of the microphone .
