Chapter 15: Wireless
125
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
“RADIO
FREQUENCY INTERFERENCE” ON PAGE 146
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.
The wireless MP-70/50 has been programmed to use the correct score-
board type and data format as instructed in “PROGRAMMING THE SYSTEM SET-
TINGS” ON PAGE 149.
Selecting transmission modes
Before operating the wireless MP-70/50, you must select a transmission
mode. The wireless data link can operate in one of two modes:
• SELECT CHANNEL mode (SEL) - In SEL mode, you can operate more
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.
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.
