MP-70/50 Scoreboard Controller User’s Guide
140
ALL, the MP-70/50 controls all scoreboards within range, regardless of
which select channel they are using.
When a scoreboard is locked onto a SEL mode signal, it ignores any trans-
missions from an MP-70/50 set to ALL. If you turnoff an MP-70/50 that is
controlling a scoreboard in SEL mode, the scoreboards continues to ignore
any transmissions from an MP-70/50 in ALL mode for 10 seconds. After 10
seconds, it responds to transmissions from an MP-70/50 in ALL mode.
To operate some scoreboards in SEL mode and others in ALL mode, turn
on the scoreboards and MP-70/50 using SEL mode first. Then turn on
those using ALL mode.
Note: Scoreboard display flickering or flashing may
result when more than one MP-70/50 control is oper
-
ating in ALL mode at the same time.
Note: The ALL RADIO TRANSMIT mode is not avail-
able on outdoor scoreboards or field timers. The
select channel on the MP-70/50 control and on the
receiver card (inside the scoreboard) must be set to
the same channel, and the MP-70/50 control must be
operated with the RADIO TRANSMIT mode set to SEL
mode.
