Caution:
Always turn off the screener before connecting or disconnecting any component, to avoid
damaging the device.

Do not allow cables to dangle from the screener, or to hit hard surfaces. Damaged cables may
cause incorrect screening results.
Natus screening supplies have been validated for use with the Natus ALGO hearing screeners.
Natus does not support any screening results obtained with supplies from other manufacturers.
Natus Earphones
Natus Sensors
Natus sensors are specialized low impedance electrodes which allow the ABR signals to be
transmitted across the infant’s skin to the ALGO 3i screener. Natus sensors are coated with a
conductive adhesive designed for use on neonates.
Natus earphones isolate the ear from background noise while avoiding introduction of probe tips
into the infant’s ear canal. Only Natus earphones have been validated to yield the appropriate
acoustic performance for use with the ALGO screening system.
Skin prepping materials, such as NuPrep
®
gel, remove surface oil or skin debris at the sensor sites
on the baby. These products lower the electrical impedance of the skin and can improve the
sensor connections. Your service representative can provide information and options for ALGO
screening supplies and prepping materials.
