4-3-2 TOUCH SCREEN BLOCK ASSEMBLING
The critical step is the positioning of the cover upon the screen
1. Place the cover sliding carefully the cables inside the aperture.
2. Place 2 screws identified A on the picture without screwing them
completly in the way to pre position the cover.
3. Approach the 4 screw without head gently inside there screen
housing and let absolutly 3 or 4 mm outside of the cover.
WARNING : Never tighten hardly these screws.
The new tactile glass must be replaced with 3 new flat strip joints and
one new flat joint.
1. Place the 3 new flat strip
joints on the metalic support.
Place the short strip on the
down part of the metallic
piece.
Take care to have the strips
layed flat and not
superimposed.
2. Place the tactile glass
carefully with the green way
above
3. Place back the flat joint. The
washer doesn’t need to be

5. Continue to slide the 4 screws without heads inside the tubes by
screwing without never tight them. The pressure of these screws
on the glass must be at the minima.
WARNING : Never tighten hardly these screws.
A too high pressure of the screw rods on the screen can
break the tactile glass or causes disfunctioning of it.
6. When the screws are in a ligth contact with the top of the tube,
keep the screws in position with an Allen key and lock this position
with the nuts.
CAUTION : After the screen assembly mounting, a touch screen calibration
must be performed (see chapter 5-1 Touch screen calibration).

5- MAINTENANCE
5-1 TOUCH SCREEN CALIBRATION
The position of the touch-screen-sensitive area can be calibrated.
It can be necessary after a transport, a screen assembly changing, a
software upgrade or other wich could change the touch screen calibration.
This calibration can be done only if the Aviso software on thce computer is
not started or if the Aviso and the computer are not linked.
Switch ON the Aviso and wait for the home page to display.
Turn the power knob clockwise until 'Calibration' displays on the screen.
NOTE : Read the entire procedure before to start.
1- Press the ‘START’button.
2- Wait for the first beep;
it is the begining of the calibration
procedure.
3- Press ‘P' until to hear the
second beep.
4- Then press successively the 4
screen corners.
Each time a corner is pressed,
repetitive beeps will be hear.
It means that the screen pressure is
correctly recognized.
Go to the following corner.
NOTE : To obtain a better result, it is recommended to press the screen
with a thin plastic stick, like a PDA pencil.
5- Press 'P' again to complete the procedure.
6- At the end, you can save the new calibration and exit by ‘SAVE’ (the
screen comes back to the home page), abort the procedure by ‘ESC’
or start it again by ‘START’.

With a screwdriver pull the
main fuses block at the
rear of the Aviso.
5- MAINTENANCE
5-3 A-PROBE CALIBRATION
Biometry and ProBeam probes can be installed and used on the 3.0 Aviso
software, without doing a calibration between each use of the probe.
A calibration can be performed for each probe, and permits to get the
correct position of the first marker in Contact.
Important: After installing the new software version, the calibration of the
probes is not saved (due to the modification of the biometry and
probeam controls), so you have to perform the biometry calibration
for each probe: Biometry and ProBeam probes. Before to upgrade,
you can note the zero parameters and the cursor position, then
perform the upgrade and insert the noted parameters, but you have
to check the calibration is correct.
Procedure:
• Run « Aviso_Setup.exe » software, in the « C:\Program Files\Quantel
Medical\Aviso » directory.
• Click on « Setup » and select « Probes » tab,

SERVICE MANUAL
If no biometry and/or ProBeam parameters have been installed, you
have to:
Click on the « Add » icon,
Select the CD-Rom drive,
Select the « .prb » file,
Click on « Open », the probe is added in the list.
If the biometry and/or ProBeam parameters are installed, you have just
to perform the calibration of each probe:
Select the probe to calibrate in the list, (the selected probe is
highlighted in blue),
Click on the « Test Block » key to perform the probe calibration of the
selected probe and get the correct position of the first marker.
5- MAINTENANCE
The following window is opened, by clicking on the « Test Block » key: the Zero
(Probe) value is set at 0.16mm by default.

SERVICE MANUAL
5- MAINTENANCE
In the below example, the best measurement is equal to 10.35mm, adjust the
cursor to get 10.00mm.
Put a drop of water on the tip of the probe, and put the tip of the probe on the
test block.
You have to measure 10.00mm on the test block in the « Best » field, which
corresponds to the minimum measured value: when the probe is well
perpendicular and in the centre of the test block.
If you do not measure 10.00mm, you have to adjust the « Position of Marker
#1 in Contact » and the zero field to get 10.00mm in the best field (in the
current field, you can display between 10.00mm and 10,08mm, depending
of the probe position on the test block).
best
measurement cursor 10.00mm
The correct adjustment displays a value of « -0.38 » in the « Position of
Marker #1 in Contact » field, you have to subtract this value to the Zero
(Probe) value: that is to say: 0.16 – (-0.38) = 0.54.
Fill the Zero field with the « 0.54 » value, the cursor field is automatically set
to 0:
Check the correction is ok, by
measuring the test block
again. If not, you have to
perform again the calibration.
Ok: permits to save and validate the
calibration,
Clear: permits to erase the Best and
Current values.
