Using non-compliant pacemakers may result in the operation of the pacemaker being
affected by the use of Nox A1 recorder and lead to possible patient harm. Prior to using the
device with pacemaker patients, the operator should consult the accompanying documents
of the pacemaker regarding its certifications and requirements of use or, if necessary,
contact the producer..
Warning: The Nox A1 recorder is not defibrillator proof. Not removing the device from a
patient before defibrillation may lead to the creation of high current density at the electrode
sites, causing burns and leading to possible patient harm. Not removing the device from a
patient before defibrillation may also alter the intended flow of the current, affecting the
defibrillation efficiency and causing injuries or death of the patient.
Warning: The Nox A1 recorder and is accessories are not intended to be used with high
frequency (HF) equipment. Using the device with high frequency (HF) equipment could cause
potential serious harm to the patient.
Warning: The Nox EEG Head Cable/Nox 5 Lead EEG Cables do not provide protection against
the effect of the discharge of a cardiac defibrillator nor against high frequency burns. Not
removing the equipment from a patient before defibrillation may lead to the creation of high
current density at the electrode sites, causing burns and leading to possible patient harm.
Warning: The Nox A1 recorder and accessories are not designed to give a specified degree of
protection against harmful ingress of liquids. Do not autoclave or immerse the device in any
kind of liquids. Ingress of liquids may result in electric shock.
Warning: In the United States of America, only use United States Environmental Protection
Agency (EPA) registered products for cleaning/disinfection of the Nox A1 recorder and
accessories to prevent harm to the operator/patient.
Warning: The Nox A1 recorder is NOT suitable for use in presence of a flammable anesthetic
mixture with air or with oxygen or nitrous oxide. That could lead to the creation of
electrostatic charges or temperature exceeding limits resulting in sparks or ignition, causing
burns or explosions.
Warning: Do not use the Nox A1 recorder and accessories during radiography/X-ray studies.
The energy absorption in the device, cables or electrodes might lead to excessive heating and
cause burns.
Warning: As with all medical equipment, carefully route cables and connections to reduce
the possibility of entanglement or strangulation.
Warning: Do not use any part of the Nox Sleep System, including patient cables and
electrodes, in a MRI (Magnetic Resonance Imaging) environment. The energy absorption in
conductive materials might lead to excessive heating and cause burns.
Caution: The Nox A1 recorder and RIP belts should be worn over clothing to prevent allergic
reaction to the equipment materials.
Caution: The Nox RIP belts should fit the patient snugly without being uncomfortably tight to
avoid discomfort.
Warning: The Nox disposable RIP belts, Nox nasal cannulas, Nox filter tube connectors and
mask pressure tubes are single patient use. Re-using the disposable RIP belts may affect the
quality of recorded signals and lead to possible incorrect treatment. Using the same
disposable RIP belt, cannula, filter tube connector and mask pressure tube on more than one
patient poses a risk of cross-infection.
Warning: Do not use damaged equipment, sensors, or accessories. This may result in bad
performance of the Nox Sleep System or patient/operator injury.
Warning: The Nox A1 recorder and its accessories should be removed from the patient
before use of the USB connector to prevent electrical shock. The USB connector shall only be
