Device Orientation


Handheld Unit


Attaching the Probe the Probe

•Plug end of probe into socket located at the top of the base unit.

•Line up the Maico Logo on the probe with the front of the base unit and insert the plug fully into the socket.

•If probe is not plugged in, a prompt will display on the screen when a test is started


Parts of the Probe

Probe Probe Tube Ear Tip

Fully assembled probe for testing


Charging

• Integrated lithium-ion battery• Charge via power supply• 15 hours of use-time between full charges• Blue LED Charge light indicates charging status• Battery status indicated on Main Menu screen


Blue Charging Light

When device is plugged into charger:• Instrument displays “Charging” then powers off. Blue light indicates

status: Steady-state: battery fully charged Slow blink: charging in process Fast blink: fault condition, return

for service

When device is in use:• 2 fast blinks, pause: low battery,

needs to be charged


Battery Status Indicator

Battery status indicator on Main Menu screen during use

• Full battery symbol represents full charge

• Reduces to empty battery in increments corresponding to discharge of battery

NOTE:•Battery life can vary based on product configuration.

•For maximum battery life, charge when 5-10% of battery remains, rather than fully depleting it.


Navigation

• 4-way arrow keys ()• Prompts on screen indicate arrow function

Turn On: press down arrow ()

Turn Off: powers down automatically after 1 minute (default)

OR press & hold up arrow ()


Start-up Screen

• Model• Firmware version• Serial number• Calibration due date

Information displays for several seconds, then screen goes to Main Menu


Main Menu Screen

• L/R arrow to start test

• Down arrow to change protocol

NOTE: The UP key () will always bring the instrument back to either the previous menu or the main menu. The UP key will also access the print command from the Main Menu.


Selecting a Test Protocol

1. Press CHANGE on Main Menu

2. Press CHANGE to select a new protocol

3. Press UP arrow to return to the Main Menu to begin testing

(Press SETUP to enter the setup menus)


Conducting a Test


Select & Attach an Ear tip


Insert Probe

• Probe should be snug, but comfortable

• Deeper fit is better for OAE measurement

• Probe should remain in place on its own without any hand-holding


Starting the Test

• Press LEFT or RIGHT to begin test

• Probe check screen will display. This checks for a good probe fit and seal in the ear (which blocks outside noise). When the scale displays green the test will progress.

• If the scale is in the amber color all the way to the left, the probe does not detect that it is inserted into an ear. If the scale is grey, it has not yet detected a seal. Once a seal is detected , it will turn green.


Starting the test with P.E. Tubes

If testing a patient with P.E. Tubes in place: • Press and hold Right or Left arrow to test.

Note: Pressing and holding the right or left key bypasses the probe-check, which checks the stability of the probe in the ear and can be affected by a large ear canal volume which is the case with P.E. Tubes. If no tubes are present, always allow the probe-check to sequence on its own and do NOT by-pass it by holding down the arrow keys.


Test Sequence

• Progression of test displayed on the screen. Each column is a frequency (kHz). Bars represent signal-to-noise ratio (SNR) in dB. Value graph screen displays level of noise floor () and OAE ( or ).

• When test is finished, result is displayed.

• Begin test in opposite ear by pressing LEFT or RIGHT

SNR Graph

Value Graph


Results

• “PASS” on the screen indicates the patient passed the screening.

• “REFER” indicates that the patient did not pass the screening, and should be referred for further testing.

• “NOISY” indicates that excessive noise was present during the test. Reduce noise sources, and test again.

• “NO SEAL” indicates that a seal was not maintained throughout the test.Try fitting with a different ear tip and test again.

• “FIT ERR” indicates inadequate probe placement in the ear canal to produce target stimulus intensities.

Try a deeper fit in the canal, and test again.


Results

General Rule of Thumb:

When the test result is “Noisy,” “No Seal,” or “FIT ERR” the tester should reposition the probe, selecting a different size ear tip if necessary, and retest.


Storing Results in Instrument

The result is automatically stored in the instrument. (NOT long term storage)

Storing Options:

1. Save as R/L ear for one patient• A new test will overwrite result of the previous test

2. Save 250 tests• All tests will be saved and not be overwritten• Tests are numbered 1 through 250• Must keep track of patient test number(s)

3. Save under Patient Name• Requires use of Database software• Device should be set to save 250 tests if using patient names• Tests will be saved under patient name instead of numbered

** Results should then be Printed to Thermal Printer or saved to Database for long-term storage or test review. **

Database & Patient Names

• Patient names can be loaded into the ERO•SCAN unit through the

database software. (Note: set device to store 250 tests).

• Tests can be performed under specific patient names and then reloaded back into database.

• Tests in unit can also be saved as regular R/L tests and loaded into database as an un-named patient.

• The un-named test results can then be dragged to a patient name in the database.
