Selecting channels
In SEL mode, you must select the same channel on both the SP-70 and its
receiving devices (scoreboards and timers).
Valid channel numbers are 0 to 15. Most of the SP-70 controls manufac-
tured by Fair-Play are set up at the factory to use channel 3 to control
indoor scoreboards. You may keep this selection, or change it, as you pre-
fer.
On the receiving device, the CHANNEL SELECTOR SWITCH is a 16-posi-
tion 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 trans-
mitter on the SP-70 when the radio transmitter is in SEL
mode. Likewise, the receiver located in a wireless score-
board is disabled when the channel switch is set to 0, E
or F.
