Back to Table of Content Page Device Orientation
Back to Table of Content Page Handheld Unit
Back to Table of Content Page 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
Back to Table of Content Page Parts of the Probe Probe Probe Tube Ear Tip Fully assembled probe for testing
Back to Table of Content Page 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
Back to Table of Content Page 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
Back to Table of Content Page 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.
Back to Table of Content Page 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 ( )
Back to Table of Content Page Start-up Screen Model Firmware version Serial number Calibration due date Information displays for several seconds, then screen goes to Main Menu
Back to Table of Content Page 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.
Back to Table of Content Page 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)
Back to Table of Content Page Conducting a Test
Back to Table of Content Page Select & Attach an Ear tip
Back to Table of Content Page 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
Back to Table of Content Page 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.
Back to Table of Content Page 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.
Back to Table of Content Page 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
Back to Table of Content Page 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.
Back to Table of Content Page 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.
Back to Table of Content Page 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. **

Back to Table of Content Page Printing & Saving Results
Back to Table of Content Page Printing Results to Thermal Printer 1.From the Main Menu, press the UP button to enter the print screen 2.Press the CONNECT button 3.EROSCAN will find paired printer 4.All test results will print automatically 5.Printed results will store in memory until a new test is started
Back to Table of Content Page Results Results displayed on screenResults displayed on thermal printout Frequency (kHz) Signal-to-Noise Ratio (dB) -OR- Level (dB SPL) Frequency (kHz)
Back to Table of Content Page Saving Results to Database 1.Open EROSCAN Database on PC. 2.Connect EROSCAN unit to computer via included USB/micro-USB cord. 3.Make sure EROSCAN unit is turned on. 4.“READY” will display on EROSCAN screen. 5.If this is a new or different EROSCAN device, click “Detect Com Port.” 6.Click “Results.” 7.Results in the EROSCAN unit will download to database.
Back to Table of Content Page Printing Results from the Database 1.Highlight the results to be printed 2. Click “Print”
Back to Table of Content Page Database Software Printout
Back to Table of Content Page Database & Patient Names Patient names can be loaded into the EROSCAN 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.
Back to Table of Content Page Set-Up Menu
Back to Table of Content Page To Enter Set-Up Menu: 1.Press CHANGE at the main menu. 2.Press SETUP at the Protocol screen. 3. At the Clock menu, hold down the CHANGE key for 3 seconds until the Ready light (green LED) turns off and release the key. You are now in the set-up menu Press & hold for 3 seconds
Back to Table of Content Page Pairing a Printer 1.Enter Set-up menu, press NEXT to get to “New BT Device” 2.Turn on the device to be paired (i.e. thermal printer) 3.Select DISCOVER 4.EROSCAN will scan to discover all available BT devices (15 sec.) 5.Use CHANGE buttons to select desired device 6.Press PAIR to pair the device 7.Pairing will be confirmed Step 1-3 Step 4 Step 5, 6 Step 7 NOTE: Printer should only have to be paired once upon initial set-up or if changing the printer. Once device is paired, print as normal from main menu.
