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.
