Turning power off or changing channels does not change the power
setting selected for a channel.
Emergency Mode (Conventional)
On conventional Project 25 channels, an emergency mode may be
programmed to be selectable by the orange Emergency switch located on
the top panel (see illustration on page 15). Scanning is automatically
disabled in this mode, so transmissions occur on the selected channel.
Pressing this switch with a Project 25 channel selected enables the
emergency mode and if the PTT switch is pressed, an emergency status is
sent. Radio power must be turned off to cancel the emergency mode on a
Project 25 channel.
If this switch is pressed with an analog channel selected, an emer-
gency condition is not transmitted. However, if a Project 25 channel is
selected before power is turned off, the emergency condition is trans-

NOTE: If your radio is programmed to transmit emergency conditions,
consult your system operator for more information on the specific opera-
tion in your application.
