Calibration for loud ambient noise: Adjustment of internal microphone sensitivity
The equipment allows adjusting the sensitivity of the internal microphone so that the teller
does not need to get too close to the microphone to be heard properly.
It is necessary to calibrate the microphone sensitivity according to the ambient noise
inside the barrier. If the sensitivity is inadequate for the ambient noise, the audio may
become choppy.
The sensitivity is set using the slide switch on the
bottom of the electronic unit.
• Loud background inside
è
Low sensitivity
• Quiet background inside
è
High sensitivity
When the sensitivity is low, it is necessary to talk
closer to the internal microphone.

USE RECOMMENDATIONS AND MAINTENANCE
Do not move the microphone by the tip. Handle the microphone by the neck
instead of by the tip.
Do not force the microphone to bend or use
any type of binding to keep it bent.
If you want to decrease the reach of the
microphone, move it backwards leaving a
wide curve at the neck of the microphone.
