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 : StayHear+ 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.
