Weather Alert
VHF models of the Loudmouth
™
can automatically play emergency weather warnings from the National Weather
Service that is broadcast on one of the seven NOAA weather frequencies. The Loudmouth
™
will listen for
emergency weather broadcasts any time it is not being used. To use this feature the Loudmouth
™
must first be
programmed for your local NOAA weather frequency.
With Weather Alert operation:
•
The Weather Alert feature is only available on the LM-V150 model.
•
Your local NOAA weather frequency must be programmed into the LM-V150 and the Weather Alert feature
must be ON per the instructions in the Programming section of this manual.
•
If a severe weather notification from NOAA weather service occurs while the LM-V150 is in use the Weather
Alert operation will not be activated.
•
When a severe weather notification from NOAA weather service activates Weather Alert operation, the LM-
V150 will broadcast the NOAA weather alert message non-stop until an end-of-message signal is received
or 2 minutes elapses. The Loudmouth
™
cannot be used for regular paging operation as long as the weather
alert message is being played.
•
The maximum Weather Alert Time is set at the factory for 2 minutes, but is PC programmable from 20
seconds to 4 minutes. This time only matters if an end-of-message signal is not received from NOAA
weather service.

Battery Powered Operation
The Loudmouth
™
receiver comes equipped with the BP-LM9 emergency backup battery that can temporarily
power the radio if primary power from the RPS-1A is interrupted. The BP-LM9 is an 800mAH rechargeable battery
pack that is trickle charged by the Loudmouth
™
receiver and is not intended to operate the radio for an extended
period of time. For applications where AC power for the RPS-1A is not available, the Loudmouth receiver must be
powered by an ex12 VDC battery. The Loudmouth
™
can then be configured for battery powered operation
to maximize battery life.
Battery Operation Enable
Enabling this feature will put the audio amplifier into a standby mode except when a message is played.
•
Depending on usage, this may double the battery life.
•
The caller must wait approximately 1 second before speaking to allow the audio amplifier to turn on.
•
If the Record and Play feature is used the caller does not need to wait before speaking.
Power Save
Enable this feature whenever the Loudmouth
™
is battery powered to extend battery life. When enabled the
Loudmouth
™
receiver is in a low current “sleep” state the majority of the time, waking up periodically to see if
there is an incoming message to be broadcast.
•
Depending on usage, this may double the battery life.
•
The length of time the Loudmouth
™
can “sleep” before it checks for a message is PC programmable from .5
to 8 seconds.
•
With Power Save enabled the caller must wait approximately 2 second before speaker to allow the radio to
wake up.
Low Battery Alert Tone
Enable this feature whenever the Loudmouth
™
is battery powered and a short tone will be heard at the end of
each broadcast to indicate that the batteries need replacement or recharging.
The Loudmouth
™
receiver and PA speaker is not intended for use as a stand-
alone weather receiver.
