Troubleshooting

Headset

My headset is unstable.	When you wear the headset, the microphone should rest as close to your cheek
	as possible without touching. The microphone can be adjusted inward by pivoting
	the earpiece to optimize the position of the headset. See Position your headset.

I can’t subscribe a headset to the base.

Make sure both the headset and base have the red XD markings. See Subscription button in this user guide.

Desk Phone

I can’t hear a dial tone in the headset.

I hear static.

Make sure your headset is charged.

Make sure your headset is subscribed to base. See Subscription button. Press the call control button on your headset.

If using a lifter, make sure the lifter is lifting the handset high enough to operate the hookswitch; set to a higher setting if necessary.

Adjust the configuration switch on the base until a dial tone is heard. Fine tune the listening volume on the headset.

If the volume is still too low, adjust the Listening volume dial on the base.

Make sure there is at least 12 inches between your base and your computer, and 6 inches between your base and your telephone. You may hear static as your headset is going out of range; move closer to the base.

The sound is distorted.	Lower the Speaking volume dial or Listening volume dial on the base. For most
	telephones the correct setting is position 2.
	If your desk phone has a volume control, lower until the distortion disappears.
	If the distortion is still present, adjust the headset volume control to lower the
	headset speaker volume. If the distortion persists, lower the Listening volume dial
	on the base.

	position of the headset to make sure the microphone is as close as possible to
	your mouth.

	the default position.
