Troubleshooting
Range related issues : QuietControl 30 headphones have a range of up
to 10 metres (33 feet) from the source device. It is realistic to describe
the range as being the room that the user is in and the adjacent room.
This range may be reduced by physical obstructions, such as walls and
doors, or by interference from other electronic devices.
Charging and battery related issues : QuietControl 30 wireless
headphones can be charged using the USB cable supplied in the box by
plugging the micro-USB into the neckband and the USB into the USB
port on a computer or a wall charger (sold separately). Allow up to
three hours for the headphones to fully charge. (If the battery is
depleted, a quick 15-minute charge provides approximately one hour of
play time.) While charging, the power status indicator will flash amber.
Once fully charged, the power status indicator light will turn solid
green.
Maximum battery usage : The battery will provide up to 10 hours of use
per charge.
Heartips Compatibility : S QC tips are compatible with
QuietComfort 20 Acoustic Noise Cancelling headphones, but should not
be used with other Bose in-ear headphones.
Noise cancellation issues : When the user takes or makes a call, the
noise cancelling level will remain at the current setting. The user can
adjust noise cancelling up or down during a call.
