Power-up sequence for multiple controls
For systems using multiple wireless controls, observe the following power-
up sequence:
1. Scoreboards and timers.
2. The SP-70 controls set to the SEL mode.
Multiple controls can utilize the SEL TRANSMIT mode, but they must
each be set to different channels.
3. The SP-70 control set to the ALL mode. This has a limitation of ONE
set of scoreboards set to ALL. Only ONE control at any given time
should be set to the ALL TRANSMIT mode. No less than 45 seconds
should be allowed to pass between each power-up activation. For
example:
a. Turn power on to scoreboard 1
(CHANNEL SELECT SWITCH =4),
AND SCOREBOARD 2 (channel select switch =9)
b. Wait 45 seconds.
Turn first SP-70 power on.
(Mode =SEL, CH4)
c. Wait 45 seconds.
Verify that the scoreboard and shot timers set to
channel 4 are responding to transmission from
the SP-70 set to CH4.
Turn second SP-70 power on (Mode SEL, CH9
or ALL).
d. Verify that the scoreboard set to channel 9 is responding to
transmission from the SP-70 set to SEL CH9 or ALL.
