Emergency Alert Mode
The Emergency Alert feature can be used to signal members in your group of
your need for urgent help. PX650 series radios will operate in an automatic
“hands-free” emergency control mode for a total of 30 seconds after activating
the Emergency Alert. PX650 series radios in your group will automatically
advance the speaker volume to the maximum setting and sound a warbling
alert tone for 8 seconds. The alert tone is emitted from your own radio speaker
and the receiving radios in your group. After the 8 seconds alert, any spoken
words or incidental sounds at your end will be transmitted to the group for 22
seconds. For the 30 seconds duration of Emergency Alert mode, PX650 series
radio controls and buttons will be locked to maximize reception of the
emergency message.

Warning:
The Emergency Alert feature should only be used in the
event of an actual emergency. Cobra is not responsible if there is
no response to the emergency alert from the receiving group.
Note: All Cobra PX650/RX680/CXY900 series radios are fully
compatible with the Emergency Alert feature if they would be tuned
to the same channel and same privacy code. Radio brands other
than Cobra PX650/RX680/CXY900 series can receive the emergency
alert signal, but may not respond with adjusted volume settings,
locked controls, or a warbling alert tone. Users of other radio models
set to the same channel and code will hear a steady tone for 8
seconds followed by the voice transmission for 22 seconds.
