VIII. Equipment Check
Selecting “Equipment Check” from the DeviceSetup Menu allows you to adjust the display
contrast, check the ALGO 3i Device battery and confirm correct operation of the ALGO 3i
system.
A. Contrast Setting:
Use the left/right toggle buttons to adjust the contrast of the display for improved visibility in
varied lighting conditions. Press the OK button to save the setting. The default setting ensures
optimum balance and minimal color bleed.
Technical Verification using the ALGO Check Kit:
There are three equipment checks which can be performed to verify that the ALGO 3i system
is operating correctly. Performing these checks requires the Natus ALGO Check Kit (REF
040527), delivered with the ALGO 3i screener and shown below.
B. Impedance Check (Preamp3i Clip Check):
Indicates whether the Preamp3i cable is damaged, differentiating a broken cable from other
problems.
C. Acoustic Check:
Indicates whether the ATA cable is functioning properly (that the speakers are generating
clicks, and that the microphones are ‘listening’.) This test does NOT indicate calibration status.
D. Artifact Check:
Indicates whether myogenic interference is coming from the baby, the environment, or the
screener.
See below for details on how to perform technical verification using the ALGO Check Kit.
E. Battery Information:
Displays information about the status of the ALGO 3i screener’s built in rechargeable battery.
