Operational notes
Some source/display combinations may not return cleanly
from “receiver” mode, due to the way in which they handle
handshaking. If you do not get the expected result (eg no
audio is heard) even after several seconds have elapsed, it
may help to switch to another input and then back again. This
is not a fault in the HD621; it is a function of how the source
and display communicate with each other.
Handshaking between a display and a source can take some
time and you may, for example, see a series of alternating
blank and blue screens. This is not a fault.
