Breitling, a name synonymous with precision, performance, and aviation heritage, offers a range of watches incorporating sophisticated emergency transmitter technology. This article delves into the operational specifics of the dual-frequency transmitter found in select Breitling models, providing a comprehensive guide for users and potential buyers. We'll explore the intricacies of the signal transmission, address common user queries, and offer guidance on general watch operation, including winding and accessing relevant manuals.
Understanding the Dual Frequency Transmission System
Certain Breitling watches, particularly those designed with a focus on emergency preparedness and survival, incorporate a dual-frequency emergency transmitter. This system provides a crucial lifeline in distress situations, significantly increasing the chances of rescue. The system transmits two distinct signals:
* 406 MHz Digital Signal: This signal is the primary communication channel. It transmits a digital signal on the 406 MHz frequency, a frequency specifically allocated for emergency beacons by the international COSPAS-SARSAT satellite system. The signal is brief, lasting only 0.44 seconds, but repeats every 50 seconds. This pulsing nature helps conserve battery power while maintaining a consistent signal for detection. The digital nature of the signal allows for the transmission of specific identification codes, linking the distress signal to the registered owner, facilitating faster and more accurate rescue efforts.
* 121.5 MHz Analog Signal: This acts as a secondary, homing signal. Transmitted on the 121.5 MHz frequency, this is a more traditional analog signal, lasting 0.75 seconds and repeating every 2.25 seconds. While less precise in identifying the location than the 406 MHz signal, the 121.5 MHz signal is detectable by aircraft and ships equipped with homing receivers, providing a secondary means of alerting potential rescuers in the immediate vicinity. The longer pulse duration of this signal makes it easier for older or less sensitive receivers to detect. It essentially acts as a local beacon, complementing the satellite-based 406 MHz transmission.
The Synergy of Dual Frequencies:
The combination of these two frequencies provides a robust and comprehensive emergency communication system. The 406 MHz signal ensures detection by the global satellite network, relaying the distress signal to rescue coordination centers worldwide, pinpointing the location with high accuracy. Simultaneously, the 121.5 MHz signal provides a localized alert, allowing nearby vessels or aircraft to respond directly, potentially accelerating rescue efforts significantly.
Activating the Emergency Transmitter:
The precise method for activating the emergency transmitter varies depending on the specific Breitling model. Consult your watch's instruction manual for detailed instructions. Generally, activating the transmitter involves a specific sequence of button presses or a dedicated activation switch. It is crucial to understand this procedure thoroughly before needing to use it in an emergency. Practice activation in a safe environment to ensure familiarity with the process.
Battery Life and Replacement:
The emergency transmitter is powered by a dedicated battery within the watch. This battery has a limited lifespan and requires periodic replacement, typically every few years. Ignoring battery replacement can render the emergency transmitter useless in a critical situation. Breitling recommends regular battery checks and replacements as per the schedule outlined in your watch's manual. The process of battery replacement should ideally be performed by an authorized Breitling service center to ensure proper functionality and avoid damage to the watch.
