Uniden Bearcat 55XLT Information

The radio is a basic 10 channel scanner.  Nothing fancy.  If you
disconnect wall power and it doesn't have batteries in it, it will
lose it's memories.

It uses 5AA batteries.  If you put NiCd's in it, you can flip a switch
in the battery compartment and they will charge when you plug it in.
(If you use an external charger you don't have the flip the switch.
Leave it on Alkaline.)

The keypad switch "locks" the keypad so you don't accidentally press a
button and change your settings.

To program:

Turn on radio.

It will be in scan mode.  Press Manual (orange button) to stop scanning.
Press Manual button to step through channels to get to the one you want.
(Or press channel number and then manual button)

If "LockOut" is displayed it means this channel isn't being "Scanned."
You will want to lock out the NWS  WX (National Weather Service/Weather)
frequency.  Pressing Lockout will toggle the status.

To program:

Select channel.  Use keypad to enter frequency.  Use "E" for Enter
key.  If the radio displays an E this means Error.  Usually, the
frequency you typed in is outside of the capabilities of the scanner.

Once you hit the E you will immediately start hearing anything that's
out there on the frequency you entered.

Push the "Review" button and the scanner will display the frequency
that is programmed for the channel.  A "-" will be displayed for the
decimal point.

These are likely to be used differently in your area.
But they could be used the same.  Just a starting point.
RS or the NOAA web page should be able to get you
your exact NWS frequency.

There is lots of stuff out there, Amateur Radio, Public Service,
Utilities, Businesses, etc.  Have fun.

There is tons of stuff on the web.  
Use the word scanner and your state name with any search engine 
and you are bound to turn up bunches of stuff.
