On Page 7, under “Powering” there is an error in the documentation of the 655 User Guide.
In step 2 says to “Turn off the headset by pressing the call control button for 6-8 seconds until the indicator light glows red or until you hear the beep.”
This is incorrect, what this actually does is force the headset into paring mode while turned ON. It does not turn the headset off.
Holding the call control button for 3 seconds turns the headset off.
Note: The headset has to be in the ear to hear the turn off “beep” confirmation – this occurs in approximately 3 seconds. You will not be able to see the indicator light turn Red unless looking in reflective glass.
