Locate battery compartment latch (A) on top of bullhorn. 

Open and insert 8 "C" batteries (not included) into the 

battery sleeve (B). Follow battery diagram on sleeves (C) 

for battery direction. Close battery compartment.

BATTERY STATUS 

The bullhorn has 3 LEDs – low, mid, high – (D) that will tell 

you the current strength of the battery.

volume. Replace the batteries if "LOW LED" lights 
when trigger is squeezed. Remove batteries 
when not in use for an extended time period.

When you have a fresh set of batteries, you may get  

feedback when talking. To eliminate feedback, you 

need to turn down the gain. Locate the gain control (J) 

in the battery compartment. Turn until you do not hear 

any feedback. 

NOTE: For less gain, turn counterclockwise. For 
more gain, turn clockwise.
