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 are 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.
	Make sure there is at least 12 inches between your base and your computer,
	and at least 6 inches between your base and your telephone.

	position of the headset to make sure the microphone is a finger’s width from
	the corner of your mouth.
