  If, during the 2 seconds period that CK is not

flashing, PF 1 is pressed a second time, the
LED functions will advance one step from
top to bottom through the available options in

the BDLC

PD

. Although capable of displaying

three colors, only the green and red colors are
used for the BDLC

PD

.

being sent. Test transmission display is done
in red.
