code.
County sub-section code:
The last digit on the extreme left is the county sub-
section. A county may be subdivided into 9 sub-
section; each number between (1-9) represents a specific
county sub-section.
NOTE If the county sub-section code is stated as 0,
then that county is not sub-divided and all alerts for that
county will be received. To receive all of the alerts for a
given county, insert 0 into the county sub-section.
A county can be subdivided as follows:
1 Northwest
2 North Central
3 Northeast
4 West Central
5 Central
6 East Central
7 Southwest
8 South Central
9 Southeast

RADIO – HOME / TRAVEL MODE
When the unit is set to home mode, the NOAA radio will
lock on the channel according to the Channel settings.
When the unit is set to travel mode, the NOAA radio will
lock on the channel according to the setting. If the signal
strength is weak, the unit will switch to another channel
that has a good signal. The location will be set to
"C0:All". Therefore, in travel mode, you will not always
receive relevant NOAA alert messages, but it does mean
that you can receive warning information when you are
traveling outside your home area.
To switch between travel and home mode, press and
hold TR / HM.
