Special Features
Emergency Alert Mode
The Emergency Alert feature can be used to signal members in
your group of your need for urgent help. MT series radios will
operate in an automatic "hands-free" emergency control mode
for a total of 30 seconds after activating the Emergency Alert. MT
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
second alert, any spoken words or incidental sounds at your end
will be transmitted to the group for 22 seconds. For the 30 second
duration of Emergency Alert mode, MT series radio controls and
buttons will be locked to maximize reception of the emergency
message.
1. Press and hold the Emergency Alert button for 3 seconds.
2. Release the button after the LED Indicator glows red and the
alert tone begins to sound. There is no need to continue to
hold the Emergency Alert button or use PTT for your message
to be transmitted.
3. After the alert tone ends you may speak into the
microphone. Your voice or incidental sounds will be
transmitted. The LED indicator will continue to glow for the
duration of the 22 second period.
4. After 30 seconds your radio speaker will emit a Talk
Confirmation Tone and the LED Indicator will extinguish.
Operation then returns to normal two-way mode.
Note: All Motorola Talkabout EM, MJ, MR, and MT series radios
are fully compatible with the Emergency Alert feature. Radios
other than EM, MJ, MR, and MT series can receive the
emergency alert signal, but will not respond with adjusted volume
settings, locked controls, or a warbling alert tone. Users of other
radio models set to the same channel and Interference Eliminator
Code will hear a steady tone for 8 seconds followed by the voice
transmission for 22 seconds.
Warning: The Emergency Alert feature should only be used in
the event of an actual emergency. Motorola is not responsible if
there is no response to the emergency alert from the receiving
group.
Built-in Flashlight
Press and hold the flashlight button to turn and keep the light on.
The switch functions as a momentary control for the light.
Note: Turn off the flashlight when not in use to conserve battery
power.

Scanning Channels
Use scan to search the 22 channels for transmissions from
unknown parties, to find someone in your group who has
accidentally changed channels, or to quickly find unused
channels for your own use.
There is a priority feature and 2 modes of scanning ( basic and
advanced ) to make your search more effective. The basic scan
mode uses the channel and code combinations for each of the
22 channels as you have set them ( or with the default code
value of 1). The "Advanced Scan" mode will scan all channels
for any and all codes, detect any code in use, and use that code
value temporarily for that channel.
Priority is given to the "home channel," that is, the channel (and
Interference Eliminator Code) your radio is set to when you start
the scan. This means the initial channel (and code setting) is
scanned more often than the other 21 channels, and your radio will
respond quickly to any activity occurring on the home channel as
a priority.

and code combinations.
2. When the radio detects channel activity matching the

2. Briefly press the
display, and the radio will begin to scroll through the
channels. No Interference Eliminator Codes will filter what
is heard.
3. When the radio detects channel activity with ANY code (or
NO code), it stops scrolling and you can hear the
transmission. Any Interference Eliminator Code that may be
in use by that party will be detected and displayed.
4. To respond and talk to the person transmitting, press
within five seconds of the end of the transmission. The radio
will transmit using the newly detected Interference
Eliminator Code.
5. The radio will resume scrolling through the channels five
seconds after the end of any received activity.

Scanning will resume five seconds after the end of your
transmission. You may press the
any time.
2. If the radio stops on an undesired transmission, you may
immediately resume the scan by briefly pressing
3. If the radio repeatedly stops on an undesired transmission,
you may temporarily remove that channel from the scan list

4. To restore the removed channel(s) to the scan list, turn the
radio off and then back on, or exit and re-enter the scanning
mode by pressing
5. You cannot remove the home channel from the scan list.
6. In Advanced Scan, the detected code will only be used for
one transmission. You must note the code, exit scan, and set
that detected code on that channel to permanently use the
detected code.
Your radio can tune in to broadcasts by the United States National
Oceanic and Atmospheric Administration (NOAA) Weather Radio
and Environment Canada Weatheradio.
You can listen to a weather channel (see "Weather Channels and
Frequencies" table below) or set your radio to alert you to
emergency weather broadcasts that interrupt routine broadcasts.
When you listen to a weather channel, you cannot use your radio in
scan mode or for two-way communications.

Both NOAA and Environment Canada have transmitters located
throughout the United States and Canada, respectively. These
transmitters broadcast watches, forecasts, and other information 24
hours a day.
Note: NOAA weather radio stations are assigned to cover specific
areas and service may be limited. Please check with your local
weather office for frequency and details, or visit
www.weather.gov/nwr in the US or
www.msc.ec.gc.ca/msb/weatheradio in Canada to view the
appropriate transmitter for your area.

As with two-way radio reception, weather channel reception
depends on how close you are to a transmitter and whether you
are indoors or outdoors. Because weather channels are
transmitted without codes, they may contain static or noise.
Weather Alert will not function while actively transmitting or
receiving in two-way mode.
