H3CS: Programming Mode
1. Press the PRG button, its blue backlighting will turn on.
2. YELP tone will be activated as the default siren tone.
3. Press the PRG button again, its blue backlighting will turn o󰀨, and
the siren will turn o󰀨.
4. Hold down the PRG button for 3 seconds to activate the siren tones to cycle to select a tone setting. The tone will change to the next
siren tone with a short press of the PRG button.
5. The tones will cycle between (1) Wail, (2) Yelp, (3) Hi/Lo, (4) Hyper Yelp, (5) Hyper Lo, (6) Whoop, and (7) O󰀨.
6. When a tone runs for 2 seconds without a button press, the current running tone will be selected.

6. To install power wires from lighting products (ie lightbar, directional lighting), strip approximately 1/4″ of insulation from the end of the
wires. Insert the wires in the appropriate terminal of the Amplier’s terminal block and tighten the screw. Note that terminals LEV1 and
LEV2 each have a 20 amp maximum current.
7. Both +12VLTG terminals should be connected directly to a 12V source. This connector provides power to LEV1 and LEV2, progressive
lighting outputs. This connection is designed so that nothing smaller than #10 gauge wire should be connected to it. If a fuse is
installed, it should be sized for the actual load of the lighting used and located as close to the battery positive as possible.
8. Ensure that there are no loose wire strands or other bare wire that may cause a short circuit. All wires must be protected from any sharp
edged that could eventually cut through the insulation. Also use an ohmmeter to verify that a short circuit does not exist between the
positive (+) leads and the vehicles chassis.
9. Perform visual check of all connections and wiring before connecting the red wire to the positive (+) terminal and black wire to the
negative (-) terminal of the battery.
Operating Instructions
Any electronic device may create or be a󰀨ected by
electromagnetic interference. After installation of any
electronic device, operate all equipment simultaneously to
insure that operation is free of interference.
IMPORTANT WARNINGS TO USERS OF SIRENS: “Wail” and “Yelp” tones are in some cases (such as the state of California) the only
recognized siren tones for calling for the right of way. Ancillary tones such as “Air Horn”, “Hi-Lo”, “Hyper-Yelp”, and “Hyper-Lo” in
some cases do not provide as high a sound pressure level. It is recommended that these tones be used in a secondary mode to alert
motorists to the presence of multiple emergency vehicles or to the momentary shift from the primary tone as an indication of the imminent
presence of any emergency vehicle.
