Recommended placement

For the best sound clarity and comfort, make sure your headset fits securely and is placed with

the microphone boom pointing towards your mouth.

Your headset comes configured for your right ear with a pre-installed small ear tip and medium

earloop. To find your best fit, try wearing the headset on each ear, as well as using different sized

ear tips, earloops, and/or using the headband.

To replace the ear tip and/or earloop

1. Gently pull the eartip from the headset.

2. Rotate the earloop down 90°. Note: You will feel resistance when rotating the earloop

downwards, but this is normal.

3. Remove the earloop from the headset.

4. Reinstall the earloop and ear tip in reverse order as shown above. Be sure the notch in the

eartip faces the microphone.

the corner of your mouth.

Article ID:

000007808

Question

Why doesn't my headset fit properly?

Answer

When you wear the headset, the microphone should rest as close to your cheek as possible without

touching it. The microphone can be adjusted inward by pivoting the earpiece to optimize the position

of the headset.

CS540-XD/CS545-XD Troubleshooting:

Hearing Three Low Tones

Question

When I am on a call, I hear three low tones or the call gets disconnected. Why does this happen?

Answer

Three low tones in the headset is an out-of-range warning. You may hear this warning if:

You are on a call and go out of the operating range of the headset. You hear a single mid

tone when you are back in range.

Your active call disconnects because you are out of range. The call is re-established when

you come back within the range. However, if you remain out of the operating range for

more than five minutes, the system drops the call.

You are out of the operating range and press the call button, you hear a single tone for the

button press and three low tones for failure to make the call.
