How Lifeguard works. Lifeguard is the advanced "man down" feature in the THR8, THR9i and THR9 Ex radios
Highlights of the Lifeguard feature in the THR8, THR9i, and THR9 Ex handheld radios. Lifeguard recognises if the radio stops moving, or remains horizontal for too long.
Life guard works as a personal safety alarm. Activate it with one key press and the radio will send a warning if there may be trouble.
If the radio detects no movement, it will generate an emergency call and transmit its position to make sure help reaches you as soon as possible.
