OPERATING INSTRUCTIONS
BATTERIES
Locate battery compartment latch (A) on top of bullhorn.
Open and insert 6 “C” batteries (not included) into the battery sleeve (B).
Follow battery diagram on sleeve for battery direction. Close battery
compartment.
If using a H-6420 Rechargeable Battery Pack, first charge the battery by plugging into an AC outlet (110V-240V). Battery will reach full charge in approximately 4 hours. LED light will turn green once fully charged. Then, remove battery sleeve (B) and insert battery pack into the battery compartment of the bullhorn with the LED light facing up. Plug the cord into the two pin connector located to the lower left of the battery compartment. Close the bullhorn without pinching cord.
BATTERY STATUS
The bullhorn has 3 LEDs – low, mid, high – (C) that will tell you the current
strength of the batteries.
NOTE: Drained batteries do not provide sufficient volume. Replace the batteries if “LOW LED” lights when trigger is squeezed. Remove batteries when not in use for an extended time period.
TALK
Make sure that the switch (D) is in the off/talk position.
Place mouth about one inch from microphone (E), squeeze trigger (F) and speak.
To increase volume, rotate volume control (G) left to right.
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 (H) in the battery compartment. Turn until you do not hear any feedback.
NOTE: For less gain, turn counterclockwise. For more gain, turn clockwise.
