Scoreboard Troubleshooting
Radio Interference
If it has been determined that a nearby scoreboard‟s radio signal is interfering, the broadcast
and channel settings of the radio receiver inside the scoreboard(s) must be changed.
For more information, refer to the Gen V Radio Installation Manual ED-13831, available
online a
1. To locate the radio receiver, look for the small black antenna sticking out the front of
the scoreboard.
2. Open the access panel to which the receiver is
attached as described in Section 5.2.
3. The radio receiver has a plastic cover. Three status
indicator LEDs are visible (Figure 20).
Note: While it is necessary to have the scoreboard
powered on to check the LED indicators, always
disconnect scoreboard power before servicing.
4. Remove the four screws using a #2 Philips
screwdriver and lift off the cover.
5. Inside the receiver are a channel switch (S1) and
two broadcast jacks (J4, J5) with a jumper.
Figure 21 shows the different configurations for the small jumper wire that sets the
radio broadcast (BCAST) mode. Move the jumper wire to the desired broadcast
location.
6. Use a small flathead screwdriver to set the S1 switch to the desired channel (1-8).
7. Screw the cover back on and securely close the access panel.
8. Enter the correct sport code and new radio settings into the console to test the radio
control (refer to the appropriate scoreboard controller manual).
