@ Precautions
2. This unit uses infrared rays. Therefore, commands may not be
received
properly
if
the
front
panel
of
the
TX-860/840
is
exposed
to bright light. To prevent this from occurring, place the
TX-860/840 so that it is not directly exposed to a bright light.
3.
The
batteries
of
the
remote
contro!
transmitter
must
be
replaced
periodically.
Remember,
however,
that
commands
will
be
re-
ceived
only
when
the
power
switch
of
the
TX-860/840
is
on.
4.
The
transmitter
operates
up
to
a
distance
of
about
five
meters
(16
feet).
the
transmitting
window
must
always
be
pointed
at
the
reception
window
when
a
command
is
sent
to
the
receiver.
5. if the TX-860/840 is placed inside an audio rack behind a glass
door, the door should not use colored glass or have any deco-
rations on it since this could shorten the range or prevent
commands from being received.
6. Use of other infrared remote control devices in the same room
may cause interference.
7. If this remote control transmitter does not operate properly,
confirm that the batteries are not dead. If the problem persists,
contact your Onkyo service center.
