If you use a Plantronics CS540 wireless headset, congratulations! The CS540 is a wildly popular wireless headset for office workers and for a lot of good reasons. Among them include it being lightweight, comfortable, excellent sound quality and versatile. In spite of its enormous popularity, you can experience sound quality issues that can leave you confused and frustrated and not knowing what to do to get things fixed.
In this blog I’ll attempt to provide you with some quick fixes to the five most common sound quality issues associated with the Plantronics CS540 wireless headset.
What do you say we get started….
One of the most common reported problem with the CS540 wireless headset, also known as the C054, is ….
Echo is almost always associated with having volume up too high.
- Turn your phone volume down to half way.
- Lower your headset microphone volume to the number 2 setting. If you’d like more information on how to do this, check out one of our blogs on the subject by clicking here.
- Adjust down your headset listening volume. The red dial can be located on the bottom of your CS540 charging base. Set it to number 3.
- Position your microphone two fingers width from the corner of your mouth and just below your lower lip.
- Confirm that your configuration/compatibility switch is set on the right letter. The most common setting is “A” but your phone might require a different setting. If you need help determining which is right for your phone, contact us and we’ll help.
Another common issue that Plantronics CS540 users experience is….
- If you hear static when roaming, the static you hear might be due to you being out of range. Move closer to the headset base and see if the static disappears.
- Make sure that your CS540 base is at least 12 inches from your computer and 6 inches from your phone.
- Check the compatibility switch. Make sure it’s on the right setting for your phone.
- On the back of the CS540 base, move the wideband/narrowband switch to both settings and see if this improves the sound quality.
- Lower your microphone volume. If it’s too high, it can have a negative impact on sound quality. Move down the volume slowly and see if the sound improves.
- If you have a short in the telephone interface cable, it can give you a crackling static sound. Exchange it and see if the sound improves.
- If your CS540 battery is old and struggles to hold a charge, try replacing the battery.
- You might have a defective unit. If other CS540 headsets are in use, borrow one and pair it to your base. If the sound is acceptable, then you likely have a bad headset top.
