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. 

 

 

 

 

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 external +12 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. 

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.
