Note: Always disconnect scoreboard power before servicing.
1. Locate the black antenna - typically sticking out the front of the scoreboard - and the receiver unit will be directly behind it.
2. Use a Phillips head screwdriver to gain access inside the scoreboard and reveal the receiver unit. The receiver unit is a black box connected to the antenna. It has a plastic cover and a window to view status indicators.
3. Remove the four screws in each corner using a longer, smaller Philips head screwdriver and lift off the cover.
4. The process of changing the radio settings depends on the generation of the radio.
Gen V (blue label): Use a small flathead screwdriver to turn the CHAN rotary switch to a new channel (1-8). Move the jumper wire on the J4 or J5 BCAST jacks to a new broadcast group (1-4) as needed. Broadcast groups 2 and 4 may only use channels 1-4.
Gen VI (gray label): Use a small flathead screwdriver to turn the CHAN and BCAST rotary switches to a new value (1-8) as needed. Be sure to always leave FUNC set to 1.
Note: Regardless of radio generation, the factory default settings are BCAST = 1, CHAN = 1.
5. Screw the cover back on the receiver unit, and then securely close the scoreboard access panel.
6. Enter the new radio settings into the console to test the radio control
