EARLY WARNING ALERT SYSTEM
The early warning system uses radio signals to alert the
user to environmental dangers. A built-in radio receiver
will respond to 7 specified signal channels. To use the
early warning function, select 1 of 4 options to determine
the activity status of the radio receiver.
Radio-status options are:
•
Radio ON
[
NOAA
]
The radio is ON and voice messages can be heard
continuously.
•
Radio Standby
[ ]
The radio is in Standby and will switch to the ON
position when an alert signal is received.
•
Radio Mute
[ ]
The radio is in Standby and the LED will flash red to
indicate that the unit has received an alert signal.
Voice messages cannot be heard until the unit is
switched to the ON position.
•
Radio OFF
The radio is turned OFF and the unit will not respond
to alert signals.
To select radio settings:
Press
NOAA
to alternate between various radio status
settings. Each press will advance the setting by 1 unit.
To listen to an alert signal from the radio mute
position:
Press
NOAA
until the unit enters the radio on position
and adjust the volume level if necessary.
MESSAGE CODES USED BY THE NWR
When the NWR airs urgent warnings, a digital code
known as Specific Area Message Encoding (SAME) is
included as part of the message. This coding system
contains specific information including the localized
geographical area affected and the expiration time of the
message. The WR103N retrieves and interprets SAME
code messages and alerts the user. When SAME codes
for a specific region have been entered into the unit, the
unit alerts the user to relevant warning information for the
specified region. Once alerted, a voice broadcast can be
heard. At the end of the broadcast message, the listener
will hear a brief end-of-message static burst.
In Standby mode, the unit will retrieve messages from a
specific location and then the voice radio will automatically
activate so that voice message can be heard. Several
minutes after the message is completed, the unit will
automatically deactivate the voice radio and revert to
Standby mode.
FINDING LOCAL NWR CHANNELS AND
COUNTY CODES
Successful operation of the WR103N requires that the
user obtain appropriate NWR radio channels and SAME
codes for a specific county or region.
