MP-70/50 Wireless Option

MP-70/50
• MP-72/52 • MP-73/53 • PN 98-0002-29 • REV 1709.13
Warning:
Never apply power to a wireless MP-70/50 control that
has its antenna removed. This will immediately
destroy the output amplifier on the control’s
transmitter card, and will void any wireless MP-70/50
warranty. If the antenna has been damaged, send the
control to an authorized service center for repair.
2. Locate the MP-70/50 transmitter within a 180-degree arc in front of the
scoreboard to prevent the scoreboard from blocking the signal.
The wireless signal is largely immune to conflicting radio frequency signals from
cordless telephones, cellular telephones, microwave ovens and other radio
frequency devices. For more information on interference, see
When the scoreboard is properly receiving data from the wireless MP-70/50, the
scoring data (time, score, fouls etc.) appears on the scoreboard. If the
scoreboard or timer loses the signal, or if the signal is intermittent, the
scoreboard or timer will hold its last transmission for up to five seconds. After five
seconds, if the control still cannot detect a signal, it will display a two-digit
number that represents the radio channel that the scoreboard radio receiver is
set to.
Note: If a scoreboard takes longer than 45 seconds to respond to a wireless
transmission, it could indicate an improper equipment setup or component
malfunction.
The wireless MP-70/50 has been programmed to use the correct scoreboard
type and data format as instructed in

than one display with more than one control, simultaneously, without
them interfering with one another.
ALL SCOREBOARDS mode (ALL) - In ALL mode, you can synchronize
multiple scoreboards to one control.
