Nicolet Systems
Power source The Nicolet EEGwireless32/64 amplifier can derive its power from either an AC
outlet through the medical grade power supply, from one or two external battery
packs, or in the case of a fixed installation, wallplate power.
The Nicolet EEGwireless32/64 amplifier has a second power port, which allows the
addition of a second battery pack for longer recording time or a medical grade power
supply. If the medical grade power supply is plugged in while a battery is also
plugged in, the battery pack will charge.
There is an internal battery in the Nicolet EEGwireless32/64 amplifier that allows
switching the external battery pack while in the middle of a study. When the external
battery pack requires changing, it can be removed without interfering with the study
as long as it is replaced within 10 minutes of removal.
If an external battery or AC power is connected to the Nicolet EEGwireless32/64
amplifier, the internal battery will be charged.
Communication EEG data can be transmitted to the Nicolet acquisition system either by an Ethernet
cable or wirelessly using a recommended 802.11 b/g access point. The Nicolet
EEGwireless32/64 amplifier is IP addressable and can connect directly to a hospital
network or private LAN.
Memory card The Nicolet EEGwireless32/64 amplifier also provides onboard storage of EEG. The
Nicolet EEGwireless32/64 amplifier has an onboard memory card used to record
data. When the memory card reaches within 10 minutes of its capacity, the Nicolet
EEGwireless32/64 amplifier produces an audible alert.
Sampling rate The Nicolet EEGwireless32/64 amplifier provides selectable sampling rates from 128
Hz - 12000 Hz.
When operating at 12 kHz Sample Rate, ensure the electrode lead cover is connected.
Also, do not wrap the Nicolet EEGwireless32/64 amplifier in a blanket or place under
a pillow.

Introduction
Cleaning the system Turn OFF the system power before cleaning the instrument. Do not permit solutions
or cleaning agents to seep into the electronic portions of the system. Take special care
around controls, connectors and panel edges. Do not use any abrasive cleaners.
Remove any dust from the exterior of the system with a soft brush or clean cloth. Use
a brush to dislodge any dirt on or around the connectors and panel edges. Remove
stubborn dirt with a clean soft cloth slightly dampened with a mild detergent (soap)
or low level disinfectant detergent solution. Allow the items to air dry before next
use.
Use of detergent-disinfectants on skin may cause adverse reactions; therefore, gloves
are recommended when cleaning with these products.
Cleaning the monitor screen
When the monitor is on, the screen has a slight static charge, which attracts dust. To
remove any dust accumulation, wipe the display screen with a soft brush or lint-free
cloth. You may use an antistatic spray on the screen to reduce static buildup.

Nicolet Systems
Cleaning the keyboard
Cleaning the garment
Cleaning recording equipment and supplies after contact with Jacob Creutzfeld disease
Disinfect computer keyboards daily, when visibly soiled, or when they become
contaminated with blood. Quaternary ammonium-containing disinfectants may be
used on keyboard (Rutala et al. 2006).
Before using the disinfecting agent, perform a test on only one key
or on an old keyboard to guard against possible bleaching or discoloration of the
keys.
If a keyboard cover is used, Rutala et al. (2006) recommends it be disinfected daily.
We recommend that mobile computers used by patients be disinfected before the next
patient uses it.
Wash contaminated garments with laundry detergent and hot water or with a phenolic
household detergent. The garment should be washed and rinsed a second time without
the phenolic.
Air dry the garment only.
Ancillary electroneurodiagnostic supplies and equipment such as
cables, marking pencil, and recording instrument should be wiped down with
