Note: If you want the ALL SCBDS feature to be disabled, a lockout jumper (Fair-
Play part number C1452) is available for purchase and installation in
indoor scoreboards. All outdoor scoreboards come with this jumper factory
installed. If you want to activate the ALL SCBDS feature in your outdoor
scoreboard, you will need to have this jumper removed. Consult your
Trans-Lux/Fair-Play Help Desk for assistance.

ELECTING CHANNELS
In SEL mode, you must select the same channel on both the
MP-70/50 and its receiving devices (scoreboards and timers).
Valid channel numbers are 0 to 15. Most of the MP-70/50
controls manufactured by Fair-Play are set up at the factory
to use channel 7 to control outdoor scoreboards, and channel
3 to control indoor scoreboards. You may keep these
selections, or change them, as you prefer.
On the receiving device, the CHANNEL SELECTOR SWITCH is a 16-position
rotary switch with a small arrow indicating its position. The image below shows
this switch, which is located on the receiver card on your scoreboard. This switch
is used to select the SEL mode radio channel. Channels 10 through 15 on M-
70/50 correspond to the letters A through F on the CHANNEL SWITCH.
Note: Channels 0, 14, and 15 disable the radio transmitter on the MP-70/50
when the radio transmitter is in SEL mode. Likewise, the receiver located
in a wireless scoreboard is disabled when the channel switch is set to 0, E
or F.
