USING YOUR HEADSET ANSWERING/ ENDING/MAKING CALLS To answer or end a call, briefly press the call control button. To make a call, enter number on your phone, press send, and the call is automatically transferred to the headset; no need to press the call control button. NOTE When answering a call, wait until you hear a ring from the headset itself (not the ring from your phone), before pressing the call control button. AUTO ANSWER If the headset is placed in the carrying pocket when a call is received, the charging pocket will vibrate (Discovery 655) or light up (Discovery 665) when connected to power. Removing the headset from the pocket will automatically answer the call. Returning the headset to the charging pocket will end the call. ADJUSTING VOLUME To increase listening volume, press the upper end (+) of the volume/mute button. To decrease listening volume, press the lower end (-). CAUTION For your comfort, health, and safety, do not exceed moderate listening levels. MUTE A CALL To turn the mute on while on a call, press both sides of the volume/mute button simultaneously until you hear a beep. To turn the mute off, press both buttons again. 9
