5.6.2 NOAA WEATHER ALERT TESTING
In the event of a major storm or other appreciable weather condition requir-
ing vessels at sea or other bodies of water to be notified, the NOAA (Na-
tional Oceanographic and Atmospheric Administration) broadcasts a 1050
Hz tone that the HX270S can detect. (Refer to section 5.6.1 “NOAA WEATER
ALERT” on how to use this feature.) This tone, when detected, will produce
a loud beep from the radio speaker to signal that a weather alert is being
broadcast.
In order to test this system, the NOAA broadcasts the 1050 Hz tone every
Wednesday, sometime between 11 AM and 1 PM. Any marine VHF radio
that can detect the weather alert tone, may use this test to verify that this
feature is functioning properly.
5.7 SCAN
This transceiver provides a special “Scanning Memory Bank” which allows
you to designate certain channels for inclusion in a “loop” which will be
scanned at high speed. If an incoming signal is detected on one of the chan-
nels in the scanning loop, the radio will pause on that channel, allowing you
to listen to the incoming transmission.
1. Select the desired channel to be included in the scanning loop using the
[
]
or
[
]
key.
2. Press the MEM key to store the channel into the
transceiver’s scanning memory. “MEM” will be dis-
played on the LCD.
3. Repeat steps 1 and 2 for all the channels to be
scanned.
4. To delete a channel from the transceiver’s scan memory, press the MEM
key again while the memorized channel is displayed. “MEM” will disap-
pear from the display.
5. All channels programmed remain in the transceiver’s scan memory even
if the power is turned off.
6. Press the SQL key, then press the
[
]
or
[
]
key until background noise
is eliminated.
7. To start scanning, press the SCAN key. The scan proceeds from the
lowest to the highest programmed channel number and stops on chan-
nels when a transmission is received. Scanning will resume when the
squelch closes after the incoming signal disappears at the end of the
transmission.
8. To stop the scan, press the SCAN, 16/9, or WX key.
