The user can continue by selecting ‘OK’, causing the device to change the Biomed Preferences Screening
Parameter to 35 dB nHL only (see section VIII 3.). In this case the previous screen will be redisplayed
showing only the 35 dB nHL options. The user will reselect one of the 35 dB nHL screening choices and
continue to Step 6.
If the user selects ‘X’, the home screen will be displayed and the user can choose to manually reconfigure
the screening parameter to 35 dBnHL only through the Biomed Preferences menu (See section VIII 3.) or
use a cable that does support screening at 40 dB nHL.
Step 6: Start Screening/Check Impedances
A. Screening immediately begins after screening parameter is selected.
Caution:
When screening a baby, position the ALGO 3i display so that it is facing away from the baby.
Facing the display to the baby may cause non-physiologic noise and prolong screening times.
Caution:
Do not lay patient cables across the device during screening. This may cause non-physiologic
noise and prolong screening times.
Monitor the impedances at each sensor location. The ALGO 3i screener has a built-in impedance
monitor which is designed to verify low impedances prior to starting the hearing screening. Low
impedances result in faster screening times and fewer false refers. A general rule is that if
impedances are above 7 kOhms, you should prep prior to starting the screening (See Chapter VI.
Baby Preparation).
The impedance monitor will update to show the current impedances.
i. When both impedances fall between 8 and 11 kOhms, the ALGO 3i screener will
display an “Impedances Marginal” message. The green “OK” button will become
selected, and screening may begin at this point, but prepping is recommended. (See
Chapter VI. Baby Preparation)
ii. When impedances fall below 8 kOhms, the ALGO 3i screener will display an
“Impedances OK” message.
B. Begin screening by clicking OK. The ALGO 3i screener will advance to the Screening in
Progress window.
