contain can be considerable, enough to
damage sensitive solid-state components
in audio and computer equipment. Spikes
can also foul switch contacts and degrade
wiring insulation. They are an unavoidable
component of electric power. They are caused
unpredictably by electric motors switching
on or off (on the premises or outside), utility
company maintenance operations, lightning
strikes and other factors. Spikes (also called
surges or transients) are absorbed by special
components in the series II Series Multi-Stage
Protection Plus circuitry to provide safe voltage
levels to protect your equipment.
RFI/EMI INTERFERENCE:
Noise from rFI
(radio Frequency Interference) or EMI (Electro
Magnetic Interference) involves lower voltages
and less energy than is found in spikes, but it
is continuous rather than transient in nature.
It is not likely to cause damage, but it can
certainly be annoying, producing static in audio
circuits, “snow” on video screens, or garbled
data in computers. Noise can be introduced
into AC lines by nearby radio transmitters,
certain kinds of lighting, electric motors, and
other sources. Because noise occurs at higher
frequencies than the 50 or 60 Hz AC line, it
can be effectively reduced through use of low-
pass filtering.

1.) Symptom:
No power to the AC outlets.
possible Cause:
Circuit breaker switch has
tripped to the off position, due to excessive
load.
action needed:
remove one piece of
equipment from the Series II unit, open the
hinged switch / breaker cover, and reset the
switch to the on position.
2.) Symptom:
No power to the AC outlets,
“Protection OK” indicator is not lit.
possible Cause:
Either the AC outlet to which
your Series II device is connected has no AC
voltage present, or the unit has been subjected
to a
sustained
voltage in excess of 400 Volts.
action needed:
Plug the Series II unit into an
AC receptacle where AC voltage is present. If
the problem persists, the protection circuit may
be damaged, and require factory service.
3.) Symptom:
Extreme Voltage indicator lit.
possible Cause:
Input voltage is above 135-
140 volts
(270 – 280 volts E version),
causing
power to the unit’s outlets to be shut down.
Additionally, if the voltage is below 85 - 90 volts
at turn on, the unit will not allow AC voltage to
reach the outlets.
action needed:
Correct the line voltage, then;
turn the unit on. Consider installing a Furman
voltage regulator.

SPIKE:
This is a pulse of energy on the
power line. Spikes can have voltages as
high as 6000 volts. Though they are usually
of very short duration, the energy they
