The radiant intensity can be adjusted by the external current limiting resistor to adapt the intensity to the desired value. The given value
is for minimum current consumption. This transceiver can be adapted to > 50 cm operation by increasing the current to > 200 mA, e.g.
operating the transceiver without current control resistor (i.e. R1 = 0
Ω)
and using the internal current control.
