Scout Sport Troubleshooting the Probe 580-OAESM1, 580-OAESM2, 580-OAESM3 Troubleshooting should be conducted whenever you get excessive artifact during testing, get refer results for all patients and/or get any of the following error messages; “Calibration data suggests probe fit problem. Check probe fit.” Or “Warning! Target stimulus level cannot be reached! “ STEP 1 Checking the probe cable connection • Disconnect the probe cable from the Scout Sport box. • Inspect the round connector on the Scout Sport box. There should be one small rectangular opening surrounded by seven small circular holes. • If the round connector on the Scout Sport box is damaged, you will need to either repair or replace the Scout Sport box. • Inspect the round metal connector on the probe cable. • There should be 1 black plastic center piece surrounded by seven metal pins of approximately equivalent length. The black plastic piece should be approximately as long as the pins. • Inspect all of them, checking for broken or bent pins. • If a bent pin is found, gently push the pin back into place. • If the pin(s) and or black connector are damaged, the probe cable, will need to be repaired and/or replaced. Note: See probe replacement issues at back of guide • To reconnect the probe to the Scout Sport box, line up the probe cable connector (checking the pin alignment) properly with the round connector on the Scout Sport box. • Firmly reconnect the probe to the Scout Sport box. • Connect the Scout Sport box to a working wall outlet, using power supply, part # 520-PS12D3. • Diminished battery output can cause probe errors. • If a problem was found with the probe connection, that has now been resolved, perform a test, referencing *Performing a test using the plastic cavity (instructions at back of guide). • If the probe cable connection is good and the error messages “Calibration data suggests probe fit problem. Check probe fit.” Or “Warning! Target stimulus level cannot be reached! “ are still present, or the initial problem was excessive artifact during testing or refer results for all patients, proceed to STEP 2 STEP 2 Checking the probe body and flexible tubing • Inspect the probe body. All three metal sound delivery tubes should be straight and have no significant gaps between them. • If a problem is found with the probe body, replace part #580-OAEPB1 • Inspect the clear flexible tubing for debris or holes. • If debris and/or holes are present, replace the tubing (part # 203905). • Do not cut the tubing as this could interfere with proper sound transmission. • Make sure the clear flexible tubing is connected well to speaker A and B on the speaker module and the two metal sound delivery tubes of the probe body. • If a problem was found with the tubing that has now been resolved, perform a test, referencing *Performing a test using the plastic cavity (instructions at back of guide). • If the error message “Calibration data suggests probe fit problem. Check probe fit.” Or “Warning! Target stimulus level cannot be reached! “ are still present or the initial problem was excessive artifact during testing or refer results for all patients, proceed to STEP 3. STEP 3 Cleaning the probe Improper cleaning can result in damage to the microphone • The OAE probe should be cleaned using the Bio-logic probe cleaners, part # 203001. • Remove the disposable probe tip from the probe. • Disconnect the microphone assembly from the probe body. • Remove the clear flexible tubing from the metal sound delivery tubes on the probe body. • Thread the Bio-logic cleaning tool (part #203001) through all three metal sound delivery tubes on the probe body until the tubes are clear of debris. It is important to insert the cleaner from the back of the probe to prevent debris from being pushed inward. • Reassemble the probe. • Perform a test, referencing *Performing a test using the plastic cavity (instructions at back of guide). • If the error message “Calibration data suggests probe fit problem. Check probe fit.” Or “Warning! Target stimulus level cannot be reached! “ are still present or the initial problem was excessive artifact during testing or refer results for all patients, proceed to STEP 4. STEP 4 Checking the speaker module • Disconnect both of the clear plastic tubes from probe body • Hold one tube to each ear. • Select Collection. Begin Collection. Select OK for the Patient Information 590-SCTPB1 REV: A
•
Listen for a sound from each of the tubes. It will begin in one tube, repeat several times, then go to the other tube. • If no sound is heard from either tube, repair or replace probe cable Note: See probe replacement issues at back of guide • If a sound is audible, proceed to STEP 5. STEP 5 Checking the microphone • Repeat STEP 3, Cleaning the probe. It is important to repeat this step as a small amount of debris lodged in one of the metal sound conducting tubes can cause a failure on this test. • If problem was excessive artifact for all patients, remove the microphone from the speaker module and clean the three prongs with contact cleaner or alcohol. Dry and reattach the microphone to the speaker module • After re-cleaning the probe, perform a test, referencing *Performing a test using the plastic cavity (instructions at back of guide). • If the error message “Calibration data suggests probe fit problem. Check probe fit.” Or “Warning! Target stimulus level cannot be reached! “ appears on the screen, refit the OAE probe into the plastic cavity and repeat the test. • If one of the above error messages is still present, replace the microphone. Note: See probe replacement issues at back of guide • If the initial problem was due to excessive artifact and/or all patients give refer results, proceed to STEP 6. STEP 6 Performing a biologic check • Select a subject with known good hearing who has previously gotten a pass result on the Scout OAE. • Place an appropriate adult size ear tip in the subject’s ear. • Perform a test. • If after completing step 1 through 5, you are still getting excessive artifact during testing and/or all patients give refer results, replace the microphone, Note: See probe replacement issues at back of guide *Performing a test using the plastic test cavity • Place a probe tip on the end of the probe. • Insert probe snugly into the plastic test cavity, part #203000. • Select a screening DP or TE test. • Perform a test. • Observe the screen in the Scout program. You will see the Scout program perform a check fit and calibration. • The overall result should be a REFER. However, it would not be unusual to get a pass result at one of the individual frequencies. • A REFER result would be consistent with a probe in good working condition. Probe replacement issues: Check the part numbers on your OAE probe. Current part numbers are 580-OAESM3 (speaker module) and 580-OAEMP4-1 (microphone). If the part numbers on your OAE probe differ from those listed above, you should exchange or repair the entire probe. BIO-LOGIC PART NUMBERS Speaker Module #203903 or 580-OAESM3 Replacement tubing #203905 Microphone #203901 or 580-OAEMP4, 580-OAEMP4-1 Power supply #203908or #520-PS12D3 Plastic test cavity #203000 Probe cleaners #203001 Probe body #203902 or #580-OAEPB1
