TURNING O ROKR PRO ON AND OFF
To turn O ROKR Pro on: Press and hold the Call 
button for approximately three seconds until you hear four audio tones rising in pitch, or you see the indicator light flash red > amber > green > green.
To turn O ROKR Pro off: While O ROKR Pro is not being used for an active call, press and hold the Call 
button for approximately three seconds until you hear four audio tones descending in pitch, or you see the indicator light flash green > amber > red > red.
NOTE THE FOLLOWING:
•When O ROKR Pro is activated (and not being used for music), it is in “standby” mode, ready to answer a call. The internal rechargeable battery offers over 100 hours of standby time.
•When O ROKR Pro is turned off, it uses no power. However, the internal rechargeable battery will naturally lose power over time, and will eventually require charging.

and Volume Down 
buttons on the left stem.
•To increase speaker volume, press the front volume button 
repeatedly until you reach the desired volume level.
•To decrease speaker volume, press the back volume button 
repeatedly until you reach the desired volume level.
•While adjusting volume in phone mode, you will hear a single high tone when the maximum or minimum volume level is reached. (You will not hear these tones while adjusting music volume.)
