NOTE:
A coupler microphone extension cable (VA-131) is available from Audioscan. Standard audio extension
cables should not be used. They will substantially increase noise levels.
General care instructions
Probe tubes are for single patient use only. They may 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.
The case can normally be cleaned/dusted with a damp cloth, however if it is soiled we recommend wiping with
a mild solution of water and detergent, or with alcohol-impregnated wipes deemed safe for use on electronic
equipment. Parts that come into contact with patients (the probe module body, cable, and red and blue lanyards)
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.
