TROUBLESHOOTING
Callers cannot hear me
■
For Voice Tube models 151, 161, or 171 determine if the
voice tube is clogged or positioned improperly. Plantronics
recommends replacing the voice tube every six to nine
months.
For a temporary solution to a clogged voice tube, gently
rinse warm water through the voice tube for a minute
then manually swing or shake it dry. Make sure the voice
tube is completely dry before reattaching.
■
For Noise-Canceling models 151N, 161N, or 171N
make sure the microphone is facing your mouth and
positioned properly.
■
Verify that the transmit volume control of the modular
adapter is set properly.

For over-the-ear configurations, determine if the earloop
is properly positioned on your ear. For over-the-head
configurations, make sure the headband length is correct
so the stabilizer bars rest gently just above the ear.

Try all possible adjustments for the receiver in the over-
the-ear or over-the-head configuration.
