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

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 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

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

by pressing and holding

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

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.
