Changing Pre-programmed Exposure Settings
The Preva Dental X-Ray System allows the operator to increase or decrease
image density for all presets for a receptor simultaneously or to change each of
the technique factors for a preset individually. You can also restore factory
default settings. For charts of the factory default settings, refer to Factory Default
Exposure Settings later in this manual.
Note:
If the 12 inch cone is going to be used, configure the Preva for use with
the 12 inch cone before changing pre-programmed exposure settings.
Configuring the Preva for use with the 12 inch cone will reset exposure settings
to the default settings used with the 12 inch cone.
Note:
Before changing presets, use the table below to write down the presets
you are programming.
