Step 2: Adjusting the microphone sound level
The microphone sound level must be set according to your model of telephone for the
party on the other end to hear you clearly. This typically only needs to be adjusted once
during set-up.
1. Put on the headset. Call someone and ask for help adjusting the sound level of your
microphone.
2. Press and hold mute button for 3 seconds to enter set-up mode. You will hear a signal
when the headset is in the set-up mode. (Figure 14)
3. Increase or decrease microphone volume by pressing the upper (+) or lower (-) part
of the oval volume control button until the other person hears you clearly. You will
hear a signal each time you adjust the volume. When you reach the maximum and
minimum sound levels, you will also hear a signal. (Figure 15)
4. Press the mute button again to exit the set-up mode. If you forget, the headset will
automatically exit the set-up mode after 10 seconds. (Figure 14)
