from cordless telephones, cellular telephones, microwave ovens and other

When the scoreboard is properly receiving data from the wireless SP-70,
data appears on the statistics panels. If the scoreboard loses the signal, or
if the signal is intermittent, the statistics panel on the scoreboard goes
blank.
The wireless SP-70 has been programmed to use the correct scoreboard
type and data format as instructed in

Selecting transmission modes
Before operating the wireless SP-70, 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.
High and low power modes
The wireless data link can operate in either
•
HIGH POWER mode - In HIGH POWER mode, your control broadcasts
a signal to the display at its maximum available power output. Under
normal circumstances, set your control to HIGH POWER mode.
• LOW POWER TRANSMISSION mode - Primarily used for system test-
ing.
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.
