Audioscan Verifit - Manual (Page 18)

Verifit ® User's Guide Version 3.12  May 2015
An optional barcode scanner may be connected to a USB port to enter threshold, UCL and RECD data directly
from Audioscan printouts. Barcoded threshold data printed by some Grason-Stadler audiometric equipment may
also be scanned. Scanners other than that supplied by Audioscan may not work and are not supported by
Audioscan.
Monitor headphones
The monitor headphones supplied with the Verifit may be used to listen to the signal being measured by 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
3. verifying program settings and their notification beeps
4. demonstrating a variety of hearing aid features to parents, teachers and significant others
Plug the headphones into the jack marked "Headphones" on the right side of the test chamber, near the front.
The volume may be adjusted using the volume wheel located next to the headphone jack. Rotating it toward the
front of the test chamber increases the volume.
Failure to follow operating instructions could place the user or operator at risk.
External peripherals
Serial number 4671 and higher: An external video monitor (HDMI or DVI with adapter) may be connected to
the HDMI connector on the rear of the main display unit. The internal display and external monitor will
operate simultaneously. The external monitor must be capable of displaying 800 x 600 at a refresh rate of
60Hz. Ensure that the external display is powered up and set to the correct input prior to powering on the Verifit.
An external printer may be connected to one of the USB ports. It may be color or black & white but it must be
PCL3, PCL 5 or Postscript compatible.
Serial number below 4671: Verifits with serial number below 4671 have 15 pin VGA monitor output which
operates simultaneously with the internal display. An external printer may be connected to one of the USB ports
or to the parallel port. It may be color or black & white but it must be PCL3, PCL 5 or Postscript compatible.
The external printer must first be selected in Setup. See Printing and Storing Results
Connectors for external front and back sound-field speakers are provided. The VA-111 external speaker with a
multipurpose folding stand is available from Audioscan but any small, non-powered 4 - 8 ohm speaker having
a smooth frequency response and good efficiency may be used. The rear external speaker is automatically
selected when required by a test but the front speaker must first be selected in Setup. See External sound-field
