Why can't I get a sharp focus with my Welch Allyn PanOptic 11820 Medical Equipment?
If you cannot obtain a sharp focus or are experiencing a hazy view with your Welch Allyn Medical Equipment, the lenses may be dirty. Clean them using a clean, soft, optical-grade cleaning cloth.
Why can't I attach my Welch Allyn PanOptic 11820 to the power handle?
If you cannot attach your Welch Allyn Medical Equipment to the power handle, the lamp may not be fully inserted. Ensure the lamp is inserted with the pin firmly seated in the slot.
