Charging (Cont.)
*** You must completely charge the headset before the first use ***
Note: When the headset power is low, the headset emits five
tones at 5 minute intervals and the LED flashes red instead of
blue. Please recharge the battery.
Connect the charging cable to the mini USB jack on the right
ear cup.
The red LED indicator should light solid and stay on while
charging. Charge time is typically between 2-4 hours for the
first charge and 1-2 hours for subsequent charges depending
on the charging power.
When the battery is fully charged, the red LED indicator will
turn off.
