3. Connect a twisted pair data cable (Fair-Play part number C0170) from
the lead control SCOREBOARD PORT 1 to the relay control
SCOREBOARD PORT 1.
4. Power up the lead control as usual.
In RELAY mode data is sent via the connecting cable from the lead control to the
radio transmitter of the relay control. The relay control then sends the same data
over its own radio channel to the receiving devices. All control of the scoreboards
is accomplished from the lead MP-72/52. Any input on the relay control is
ignored. The control in RELAY mode will stay in RELAY mode until you again
apply power while holding down the
1
key. The control toggles in and out of
RELAY mode with this procedure.
Note: Turning the control off does not take it out of RELAY mode, which was the
case with firmware versions prior to Version 2.03.

NTERFERENCE
(G2)
Under normal circumstances, other wireless signals, such as a nearby cellular
phone relay tower, should not jam the wireless MP-72/52 during a sporting event.
The control’s radio signal is redundantly transmitted 16 times across a wide
bandwidth using Spread Spectrum Technology - regardless of what channel or
transmit mode your control is set to. Spread Spectrum Technology provides a
high level of reliability, and is designed to hinder interference effects from cellular
phones, cordless devices, microwaves and other Radio Frequency devices, as
well as provide security from signal jamming.
However, wireless reception capability can be affected by unrelated Radio
Frequency traffic in the area. As “stray” signals increase, reception range may
decrease.
In the unlikely event that you think you are experiencing Radio Frequency
interference, we recommend that you first change channels, which should
eliminate any problems. Contact the Trans-Lux/Fair-Play Help Desk for
assistance.
Note: The Federal Communications Commission (FCC) has certified that Fair-
Play’s wireless MP-72/52 device will not cause harmful interference to
other FCC-approved equipment.
