Green LED
1.5 Power-on
Turn on the VITA Easyshade Advance 4.0 by pressing and holding any button
on the handpiece for at least two seconds.
1.6 Calibration
The unit may only be calibrated with a new anti-infection cover in order
to prevent patient to patient cross-contamination.
1.6.1 Automatic calibration
If the base unit is connected to a power source, the calibration procedure
is carried out automatically.
Place the instrument in the calibration block holder so that the probe tip
is flush with and perpendicular to the calibration block and depresses
the calibration block (fig. 6). Make sure that the hand piece is fully seated
in the calibration holder. Do not press the measurement switch when the unit
is calibrated automatically.
A green LED in the center of the base unit is lit and shortly afterwards
the hand piece probe will illuminate the calibration block (fig. 7).
Initial calibration may take a few seconds after the unit is switched on.
Two short beeps indicate completion of calibration.
Note:
Before carrying out any measurement, the unit must
be calibrated. If power is not available to the base unit,
the unit must be calibrated manually (section 1.6.2).
