Marine Standby and Receive (Rx) Mode
Marine Standby
mode is the default mode for the radio whenever it is turned On.
From this mode, you can change current settings by becoming familiar with the
different key functions that are active in
Marine Standby
mode. While in
Marine
Standby
mode, the user will be able to transmit by pressing the
Push to Talk (Talk)
button. Users will hear signals on the selected channel(s) in
Receive (RX)
mode and
can hear alerts broadcast by the Coast Guard and NOAA.
NOTE
Coast Guard alerts are broadcast on Channel 16 and you need to have the
WX
Alert
turned On to receive NOAA weather alerts. While in
Marine Standby
mode,
you will receive any messages sent on the channel to which you are tuned.
Transmit (Tx) Mode
Transmit (Tx)
mode gives you the ability to interact with safety services, other vessels
and shore stations. When you use this capability, be sure to follow the procedures and to
observe the courtesies that govern its use so everyone benefits. See Appendix to help
you select the proper channels.
To Transmit a Message:
1.
Check to see that your radio is set to a proper channel for
the type of message you plan to send.
2.
Toggle to the
Low Power
setting for a nearby station.
3.
With the microphone about 2 in. [51 mm] from your mouth,
press and hold the
Talk
button and speak into the microphone.
The
Transmit
icon will appear on the LCD.
4.
Release the
Talk
button when you are finished
speaking. Your radio can only operate in either
Transmit (Tx)
or
Receive (Rx)
mode at any
given time. You will not hear the response to
your message unless the
Talk
button is released.
If the
Battery Power
icon begins blinking on the
LCD when the
Talk
button is pressed, the radio
will NOT transmit.

NOAA Weather Channels
Monitoring the weather will probably be a frequent use of your radio. NOAA provides
continuous, around-the-clock broadcasts of the latest weather information. Taped
weather messages run every four to six minutes and are revised every two or three
hours, or as needed. The Coast Guard also announces weather and other safety
warnings on Channel 16. Smart boaters keep an eye on safety and an ear to the radio
— and never let the weather catch them unaware.
NOAA Emergency Weather Alert
In the event of a major storm or other weather condition requiring vessels at sea
or on other bodies of water to be notified, NOAA broadcasts a 1050 Hz tone that
receivers such as your Cobra Marine VHF radio can detect and warn you of a weather
alert condition. When the
Weather Alert
mode on your radio is On, this signal will
produce a loud tone from the speaker in the radio and will automatically switch to the
alerting weather channel so the alert broadcast can be heard.
NOAA Test Alert System
To test this system, NOAA broadcasts the 1050 Hz signal every Wednesday sometime
between 11 a.m. and 1 p.m. in each local time zone. Any receiver that can detect the
weather alert tone may use this service to verify that this system is functioning properly.
These signals will be received in
Marine
or
Weather Standby
modes as described below.
Weather (WX) Standby Mode
To enter the
WX Standby
mode, press and hold the
Power Level/Weather
button. All common operating functions
of the radio will work the same in
WX Standby
mode as they
do in the normal
Marine Standby
mode. The radio will be
monitoring for all alerts in the background when in the
WX
Standby
mode when
WX Alert
is set
ON
.
Transmit
NOTE
If the
Talk
button is held down for five minutes, the
radio will automatically sound a series of beeps
and cease transmitting to prevent unwanted signal
generation and battery drain. As soon as the
Talk
button is released, it can be pressed again to
resume transmission.
