It is necessary to re-calibrate the white balance on the Digital
MacroView after replacing the lamp.
To recalibrate the white balance:
Use a fully-charged 3.5v power source.
1. Connect the head to the computer and turn the power to the
full on position see “Using the Digital MacroView system”
on page 8.
2. Shine the light on a piece of white paper approximately
3.2 cm (1.25”) away.
3. Unfold a standard paperclip and insert it into the white
balance reset hole. Push slightly to activate the white
balance reset button.
The image becomes blue on the computer screen. A live
image returns to the computer screen when calibrated.
If the screen is red then repeat steps 1 through 3 above.
