Possible Cause

Solution/Items to Check

Check that the green POWER and

amber RADIO IN RANGE indicators

on the radio receiver in the

scoreboard light up when the control

console is powered on (see Section

2.8). Keep the console between 20

to 1500 feet from the scoreboard.

Move the console 20-30 feet from

the scoreboard and test again.

Verify that both the console and

scoreboard antennae are securely

tightened and in a vertical position.

Replace the radio receiver.

No signal to driver

Check that the scoreboard is

receiving the correct 120 (or 240)

VAC power (see Appendix A).

Check that the red DS2 LED on the

driver lights up when sending

commands from the control console

(see Section 2.6).

Swap the driver with one known to

work correctly and with the same

part number to verify the problem.

Replace if necessary (see Section

2.6).

No power to driver

Check that the green DS1 LED on

the driver is always lit up when the

scoreboard is powered on

Ensure the correct sport code is

being used for the scoreboard

are set to the correct address(es)

(see Section 2.6)
