Red light near
fiberoptic of
amplifier.
Fiberoptic
connection between
NSP and Amplifier
is not correct.
Ensure NSP is turned on, ensure
amplifier power supply is turned on,
ensure amplifier is connected to
power, and ensure fiberoptic cable is
connected between amp and NSP.
Noise
Poor Signal to
Noise Ratio or
Excess High
Frequency Signal
Uncontrolled noise
sources and/or poor
referencing or
grounding scheme
The system is sensitive to
electromagnetic signals. It is
designed to detect microvolt level
signals. Cable arrangement and
external noise source management
are important. Avoid allowing
cables of the system near other
power cables, monitors, light
sources, or other electrical
equipment. Change which
electrode is used as reference to
better remove common noise, or
use noise cancellation in Central to
remove noise from the recording.

Try turning the NSP OFF using
the rear power switch. Toggle the
front power switch 5 times on and
off. Wait 5 minutes. Turn the NSP
back on. If the NSP is still not
