1� 

Locate the horn entrance panel as described in 

Location (p�4)

. Remove the 2" 

knockout on this panel. If the knockout has not been provided, use 

DWG-83502

 as a 

guide to drill one 2" hole in the panel. 

Note: 

Be careful not to damage any internal components when drilling! 

2� 

Remove the trumpet from the horn body by unscrewing it. 

3� 

Mount the bracket to the scoreboard frame using #10 hardware provided, and 

connect the horn harness to the horn wires with included wire nuts. Refer to 

DWG-

1055044

. For the TI-2003 only, refer instead to 

DWG-3054691

. 

When replacing a horn: 
a� 

Use 1/4" bolts, nuts, and lock washers provided to attach the horn body to the 

mounting bracket so that the horn is on the same side as the short flange (the 

horn should be pointing downward). 

b� 

Be sure to mount the horn to the bracket so that the wires are facing the bottom 

of the cabinet to prevent water from running along them. 

c� 

Attach the copper ground lug to the bottom-right corner of the mounting 

bracket using the bolt and serrated washer and nut provided, and connect the 

green wire from the horn to the ground lug (

does not apply to the TI-2003

). 

4� 

Route the 2-pin horn plug labeled 

P3

 to jack 

J3

 on the horn interface card, per 

DWG-

3067686

. If the harness does not reach, connect the 2-pin to 2-pin extension cable 

between the horn and the horn interface card as needed. 

5� 

Close the access panel and screw the trumpet back onto the horn body. 

6�
