Weather Receiver

will be transmitted to the group for 22 seconds. For the 30 second duration of Emergency Alert mode, MR 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, and MR series radios are fully compatible with the Emergency Alert feature. Radios other than EM, MJ, MR 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.

Keypad Lock

To avoid accidentally changing your radio settings:

1.Press and hold until displays.

2.When in lock mode, you can turn the radio on and off, adjust the volume, receive, transmit, send a call tone, and monitor channels. All other functions are locked.

To unlock the radio, press and hold until is no longer displayed.

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.

To start Scanning:

1.Briefly press the key. The scan will appear in the display, and the radio will begin to scroll through the channel and code combinations.

2.When the radio detects channel activity matching the channel and code combination, it stops scrolling and you can hear the transmission.

3.To respond and talk to the person transmitting, press within five seconds after the end of the transmission.

4.The radio will resume scrolling through the channels five seconds after the end of any received activity.

5.To stop scanning, briefly press the key.

To start Advanced Scanning:

1.Set the Interference Eliminator Code to “zero” or OFF.

2.Briefly press the key. The scan will appear in 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.

6.To stop scanning, briefly press the key.

Scanning Notes:

1.If you press while the radio is scrolling through inactive channels, the transmission will be on the “home channel”.

Scanning will resume five seconds after the end of your transmission. You may press the key to stop scanning at any time.

2.If the radio stops on an undesired transmission, you may immediately resume the scan by briefly pressing or .

3.If the radio repeatedly stops on an undesired transmission,

you may temporarily remove that channel from the scan list by pressing and holding or for three seconds. You may remove more than one channel in this way.

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. You can listen to a weather channel (see “Weather Channels and Frequencies” table for details) 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.

NOAA has transmitters located throughout the United States. 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 to view the appropriate transmitter for your area.

The use of the NOAA logo does not provide an endorsement or implied endorsement by NOAA’s National Weather Service.

Turning Weather Channel Reception On and Off

1.To turn weather reception on, press and hold for 3 seconds.

2.To turn off, press or turn the radio off and then back on.

Setting the Weather Channel

Your radio receives weather frequencies:

1.After turning weather reception on, press . The current channel flashes.

2.Press or to select the appropriate channel with good reception in your area.

3.Press to save the weather channel setting.

Setting the Weather Alert

Your radio can be set to respond to NOAA Weather Radio emergency messages. A special alarm tone sounds an alert and turns on the weather receiver to give you immediate weather and emergency information.

1.After turning weather reception on, press twice. On/Off displays.

2.Press or to select On/Off. If you activate Weather

Alert and return to two-way mode,

will display.

3.Press to save the Weather Alert setting.

4.Press to return to two-way mode.

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.
