Note: (Unless otherwise specified)
Important notes for top cover designs:
1. The transmissivity of top cover window must be mini-
mum 80% from 800 nm to 940 nm with a variation of
less than 6% across this range of light spectrum.

2. The Assert/ Deassert thresholds must be recalculated
and set in the sensor accordingly during initialization
to address variation of surface reflection and transmis-
sivity for custom cover designs. (See OFN firmware ap-
plication note and OFN mechanical guide application
note for further details).
