Operating the LED Message Board Controls
Operating the LED Message Board Controls
The Message Board is controlled entirely with the control head either through the
numeric keypad or by activating wires in the back of the control head. To activate a
message, use the numeric keypad to enter a message or use the arrow keys to scroll
up or down to select a message, then press ENT(ER). Alternatively, you can activate the
default message wire to turn on Message One, the default message.
Testing the Message Board System
LIGHT HAZARD: To be an effective warning device, an emergency warning
system produces bright light that can be hazardous to your eyesight when
viewed at close range. Do not stare directly into the lights at close range, or
permanent damage to your eyesight may occur.
To test the Message Board system:
1.
Follow all the instructions in “Wiring the LED Message Board System in the Vehicle”
on page 8.
2.
Cycle IGN and verify that the control head powers up when IGN is activated and
turns off after 15 seconds when IGN is deactivated
3.
Enter a message number through the numeric keypad to activate a message, and
press ENT. The LCD screen should display the activated message; the Message
Board should display the message as well. If there is an error, the LCD screen may
notify you.
4.
OPTIONAL: Verify that the default message (Message One) is activated when the
default message wire of the control head is activated.
5.
After the installation, check the entire system to make sure the lights are flashing
properly and all light system functions are operating properly.
