3i Newborn Hearing Screener IFU 024913 RevD Revision Date 08/05/2020

42

The ALGO 3i screener updates the result occasionally, so if you move the screener, or accidentally

disconnect a clip, there may be a delay in the reading. The outcome of the Artifact Check will be

one of the following:

PASS indicates that the source of myogenic interference was the baby. Even a sleeping baby can

generate myogenic interference. The ALGO 3i screener is functioning properly. See Chapter IX.

Troubleshooting for tips on resolving myogenic interference.

FAIL indicates that either the environment or the ALGO 3i screener is the source of interference.

Move the ALGO 3i screener to another location and repeat the test. If the result is now PASS, the
source for the interference is likely in the environment. Monitor the screening environment for

other equipment which may be causing interference.

If the FAIL condition persists, call Natus Technical Service or your authorized service

representative for help in determining other potential sources of interference.

PASS/FAIL: If the window alternates between PASS and FAIL, the source of interference is not
clear. Move the ALGO 3i screener to another location and repeat the test. If the FAIL or

PASS/FAIL condition persists, call Natus Technical Service or your authorized service

representative for help.

Cleaning the Device and Cables

Caution!

Approved cleaning solutions are isopropyl alcohol and mild soapy water solution. Do not expose

the ALGO® 3i device and cables to non-approved cleaning solutions.

sound apertures on the transducer body with cleaning solution or by inserting an object in the sound
apertures.

1.

Turn off the ALGO® 3i device and unplug the AC power adapter from the device.

NOTE: It is not necessary to unplug screening cables for routine cleaning.

2.

Use a prepackaged alcohol wipe or a lint-free cloth dampened (not wet) with 70%
isopropyl alcohol to wipe down all surfaces of the screening device and patient cables.
