If you cannot hear a dial tone through your headset, use a coin or small screwdriver to turn the telephone configuration dial until you can. Make sure that a number is aligned with the position indicator.

Place a call to someone you know. While speaking, turn the configuration dial through the four positions. Select the position that provides the best sound quality for both you and the recipient.

NOTE: Be sure to set your telephone’s volume at the mid range before adjusting the CS70 volume.
