MAINTENANCE/TROUBLESHOOTING

Maintenance for Optimum Performance

 

Replace voice tube every 6-9 months

 

Replace ear cushion every six months

 

Clean cable with a moist cloth once a month

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 6-9 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.

I cannot hear callers

 

Verify that the Quick Disconnect

 is connected.

 

Make sure the headset is positioned properly.

 

Make sure the modular adapter, if used, is installed correctly. 

 

Turn up the volume control on the modular adapter, if used.

Fit is uncomfortable

 

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.
