Strobe light model: a portion of the screen is dark
While using a strobe light model (AD3613TB, AD3713TB, AD3715TB) a portion of the live image is dark.
1. Click the settings icon in the live image window (the icon that looks like a wrench)
2. Adjust the "Strobe length" setting
Please note: The strobe length setting can only be changed when the camera is set to strobe mode (LED mode #2). If necessary, try several values for strobe length until the issue no longer occurs. This issue generally occurs around the 40x - 60x magnification range due to the reflection of the strobe light.
