High sound pressure whistle——Focused airflow design produces a sharp, penetrating sound ideal for long-distance distress signaling or directing
Take the whistle out of its case and hold the body between your thumb and index finger, keeping it steady.
Place the mouthpiece between your lips, bite gently or seal with your lips to prevent air leakage.
Use your diaphragm to deliver short, forceful breaths; produce a single long blast or rhythmic bursts for a clear sound.
In distress, blow the international SOS signal (three short, three long, three short) repeatedly to assist search and rescue.
After use, wipe the mouthpiece and body dry, return to the case, and protect from moisture and impact.
Avoid forcefully throwing or applying heavy pressure to the whistle body to prevent deformation that may cause sound failure or abnormal pitch.
Do not wrap the lanyard around the neck. Adult supervision is required when used by children to prevent the risk of suffocation.
The mouthpiece contacts the lips. Wipe it regularly with clean water or a wet wipe to maintain hygiene.
After use in humid environments, shake out any accumulated water inside the whistle and wipe it dry to prevent long-term moisture from affecting sound quality.
