Alternative Solutions
• For CP130/CP150/CP135:
– The focus ring rotations may be too far twisted. Reset this by
spinning the focus ring clockwise until it feels tight with a two finger
grasp and then spin the focus ring counterclockwise slightly. The
image should gradually move back into focus.
• For V355AF & SPC300:
– Restart the doc cam by resetting the power. This can be done by
either pressing the power button until the doc cam turns off or
unplugging the power cord, then turning the doc cam back on again
in the same manner. The document camera should focus
automatically once it has warmed up.
Alternative Solutions
• Reset the focus to default and then press the AF
Select MENUDEFAULT YES, then press AF to see if the
focus works normally. If not, please hard reset the document
camera: disconnect all cables from document camera (power
cord, all VGA cables, USB cable and other cables). After 5
minutes, reconnected everything and turn the doc cam back
on.
• You can also use Manual Focus by pressing the
focus+/- on remote control or through OSD menu.
Friendly Reminders
• The doc cam is an optical device with sensitive internal components
that can be damaged due to carelessness. While our document
cameras are designed to survive the rigors of classroom use, if they
are severely impacted (such as being dropped from the table), they
may cease functioning properly or responding to your commands.
• Don’t put objects too close to the lens. The lens may not be able to
focus on the object and the image will remain blurry. Please leave at
least a 3cm gap between the lens and the object.
• For objects that are extremely shiny or dark, it is not easy for the auto
focus to render the image accurately. Please adjust the light
conditions or use the manual focus.
