should be regularly wiped down with alcohol wipes.

Hearing instruments should be cleaned prior to introduction to the test chamber due to the difficulty of sanitizing

the acoustic foam. Custom hearing instruments must be cleaned with disinfectant towlettes (i.e. audiowipes)

prior to placing in the test for this reason and to minimize contamination of the blue putty used with the HA-1

(ITE) coupler. The acoustic foam in the floor of the test chamber is easily removed and should be replaced if

badly worn or soiled. The black rubber TRIC (Thin-tube & Receiver In Canal) adapters may be cleaned with

disinfectant towlettes if they becomes soiled with use.

Audioscan recommends periodic replacement of the blue putty used with the HA-1 coupler to ensure

cleanliness. Both couplers and coupler microphone can be wiped down with alcohol wipes as needed.

Ensure that all safety and usage recommendations on cleaning product packages are followed.

Microphone care

Binaural coupler microphone:

1. DO NOT leave the coupler microphone plugged in when transporting.

2. DO make sure that the couplers are fully connected to the coupler microphone when performing hearing

instrument tests. Coupler leakage can cause feedback and erratic response curves.

3. DO make sure the tubing on the HA-2 (BTE) coupler is free from any cracks/tears.

4. DO make sure that any replacement tubing used on the BTE coupler is either obtained from Audioscan, or is

#13 heavy wall earmold tubing exactly 10 mm (.38 inches) in length.

Probe microphone:

Debris can alter the probe module reference microphone calibration and frequency response and can

permanently clog the probe module port.

1. DO NOT reuse probe tubes. Probe tubes can be wiped with alcohol wipes for re-use with the same patient,

but must not be used with multiple patients. Attempts at ultrasonic cleaning usually result in cerumen

becoming lodged in the lateral end which causes irreparable damage to the probe microphones.

2. DO NOT attempt to open or repair the probe microphone. Attempting to repair the probe module may lead

to damage or alteration of the factory calibration.

3. DO keep the probe module and probe tubes in a clean area.

4. DO stow the probe module when not in use or when transporting the Verifit.

Mouse and keyboard

The Verifit may be operated from a mouse or a standard computer keyboard, which may also be used to enter

headers and comments on printouts. A USB mouse or keyboard may be plugged directly into any of the USB

ports provided. See Input device operation.

Monitor headphones

You can use the supplied monitor headphones to listen to the signal from the coupler or the probe microphone.

This is useful for:

1. Listening to the hearing aid to troubleshoot sound quality complaints

2. Listening to the wearer's own voice to troubleshoot occlusion effect complaints
