FastFacts 2.5: Microphone care
Coupler microphone:
1) DO NOT
twist the cable when attaching a coupler to the coupler microphone.
Turn only the coupler or unplug the coupler microphone before turning it.
2) DO NOT
leave the coupler microphone plugged in when transporting.
3) DO
make sure that the 2cc coupler is tightly screwed to the coupler microphone
when performing hearing instrument tests.
Coupler leakage can cause
feedback and erratic response curves.
4) DO
make sure the #13 tubing on the BTE (HA-2) coupler is free from any
cracks/tears.
5) DO
make sure that any replacement #13 tubing used on the BTE coupler is .38
inches in length.
Probe microphones:
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
. Debris and liquid from cleaning attempts can
lodge in the enlarged base of the probe tube and subsequently clog the probe
microphone port.
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.
