down switch (currently available only from third-party vendors) can be attached to the
accessory connector of the radio.If this feature is enabled by programming and the radio is
in a horizontal position for longer than the programmed time (0-63 seconds), an
emergency condition is triggered the same as if the Emergency button was pressed. The
emergency can be canceled by a press and release of the Emergency button.
Note Accessories, such as speaker-microphones, cannot be used with this feature.
