20 Scoreboard Troubleshooting
Radio Interference
If it has been determined that a nearby scoreboard’s radio signal is interfering, the settings of
the wireless radio receiver inside the scoreboard(s) must be changed.
1. To locate the radio receiver, simply look for the
black antenna sticking out the front of the
scoreboard.
2. Open the access panel to which the receiver is
attached as described in Section 4.2.
3. The radio receiver has a plastic cover with a
window to view status indicators (Figure 11).
Note: While it is necessary for the scoreboard to
be powered on to check the indicators, always
disconnect scoreboard power before servicing.
4. Remove the four screws in each corner using a #2
Philips screwdriver and lift off the cover.
5. Use a small flathead screwdriver to set the
CHAN and BCAST switches to a new channel
and broadcast group (1-8) as needed. Be sure to
always leave FUNC set to “1”.
6. Screw the cover back on and securely close the
access panel.
7. Enter the correct sport code and new radio
settings into the console to test the radio control
(refer to the appropriate control console manual
listed in Section 1.2).

Installation Manual (DD2362277), available
