Operational Advisories

As with any complex electronic device, it is possible for this headset to experience a failure during operation. Such a failure may include loud tones, distortion and loss of communications signal in the headset when used in the active or “on” position. The system is “on” when the rocker switch is “up”.

Note: This failure could prevent continued use of the headset in the “on” position.

These loud tones and the related loss of communications can be elimi- nated for the duration of the flight simply by switching the headset off. (The system is off when the rocker switch is “down.”) With the switch off, the headset continues to function in the passive mode, maintaining full communication capabilities.

We strongly recommend that as a responsible pilot, you ensure you can hear and recognize typical aircraft sounds while you are using the headset. Limit the volume of your headset to safe levels so it does not interfere with your ability to hear informational sounds, such as those emitted by warning alarms; i.e., stall warning, gear up.

Avoid setting the volume controls at high levels that may affect your hearing during extended periods of headset use.

The Bose® Aviation Headset Series II has been tested and found to comply with limits for a class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

•Reorient or relocate the receiving antenna.

•Increase the separation between the equipment and the receiver.

•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

•Consult the dealer or an experienced radio/television technician for help.

This apparatus does not exceed the class B limits for radio noise emis- sions from digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications. It also complies with Canadian ICES-003 Class B.

The headphones feature plush ear cushions and a lightweight frame, making them suitable for extended listening sessions without discomfort. Furthermore, the intuitive touch controls allow users to adjust volume, skip tracks, or take calls seamlessly.

Bose II has also integrated smart technology features. Voice assistant compatibility is a significant highlight, enabling users to access their device’s voice assistant with ease. Whether it's checking the weather, sending a message, or playing music, hands-free control enhances convenience.

Battery life is another crucial aspect of Bose II products. The devices typically offer long-lasting playback time, with quick charging capabilities. Users can enjoy hours of uninterrupted listening, making them perfect for travel and daily commutes.

Durability is woven into the design philosophy of Bose II, with many headphones and speakers featuring water-resistant properties. This added resilience makes them suitable for both indoor and outdoor use, catering to an active lifestyle.

Moreover, Bose II products often come with a companion app that allows for further customization. Users can adjust equalizer settings, manage noise cancellation levels, and access software updates, providing a personalized audio experience.
