Microphone Extension Cables (EC-04 series)
Turn power to the unit off before separating the microphone from the main
unit.
To reduce measurement deviations due to refraction effects and the acoustic
influence of the operator, the microphone can be detached from the unit and
connected via an extension cable. Optional cables are listed in the table below.
It is also possible to connect several cables in series.
