Avoid setting more than one control at a time to the ALL SCBDS mode,
as this will cause the scoreboards to flicker. (For more information, see

on page 85 ).

channel setting, as this will cause scoreboards tuned to that channel to

Before establishing communication between a control set to ALL SCBDS
and its intended receiving scoreboards, be sure to have established
communication between the controls operating in the SEL mode and its
intended receiving scoreboards. Otherwise, the scoreboards you intend
to run with a control tuned to a particular channel in the SEL mode will be
likely to lock onto the signal from the control set to ALL SCBDS, and may
not respond to the intended SEL mode control when it is turned on. (For

PERATING WIRELESS UNDER SPECIAL
CIRCUMSTANCES
The following sections will give you pointers on setting up and operating the MP-
70/50 control under special circumstances you may encounter. Keep in mind
that:
A control set to ALL SCBDS will transmit indiscriminately to all wireless-
equipped scoreboards in its range, regardless of what channel these
scoreboards have their receivers set to, except for receivers equipped
with a lockout jumper (part no. C1452) installed.
A control set to the selective (SEL) transmission of channels 1-13, will
transmit to all scoreboards in that vicinity that have their receivers tuned
to that particular channel. Hence, a control set to channel 7 will transmit
to all scoreboards in that vicinity that have their receivers set to channel
7.
