NTERFERENCE
Under normal circumstances, other wireless signals, such as a nearby cellular
phone relay tower, should not jam the wireless MP-70/50 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.
Note: The Federal Communications Commission (FCC) has certified that Fair-
Play’s wireless MP-70/50 device will not cause harmful interference to
other FCC-approved equipment.

ELL FILTER KITS
If you encounter a situation where your wireless scoreboard lights start flickering
for no apparent reason, or your scoreboard exhibits sluggish responses (i.e., the
clock does not run at a normal cadence), or you experience signal loss or
dropout, contact the Fair-Play Help Desk. These problems can often be solved
with the purchase of an in-line filter kit, (part no. 08-1003-00-2 with C1516 cable,
or part no. 06-0076 -01). These in-line filter kits are installed between the
antenna cable or receiver. Outdoor scoreboards built after Oct. 17, 2005 should
already have had a 08-1003-002 in-line filter kit installed at the factory.
