Remedy
• Set the component code correctly. If the code that is listed first for your
component does not work, try all the codes for your component in the
order in which they are listed in the supplied "Component Code
Numbers."
• Some features may not be preset. If some or all of the keys do not
function correctly even after you have set the component codes, then
use the learning function to programme the remote control signals for
the component (page 15).
• The component may be operated with a code number that is not listed
in the "Component Code Numbers." See "Finding a component code
with the Search function" (page 11) and try setting a code number
again.
• If your visual components are connected to an audio system, make sure
you have set up the Commander as described in "Controlling the
Volume of Visual Components Connected to an Audio System" (page
21).
• You have assigned another component to the TV or AMP button (page
32). In this case, the volume cannot be controlled when you select a
component other than TV or AMP.
• When you teach signals of an interactive signal exchange system remote
control unit (supplied with some of Sony's receivers and amplifiers) to
the Commander, the response signal of the main unit may interfere with
the learning of the Commander. In such a case, move to a place where
the signals will not reach the main unit (e.g. other rooms, etc.).
• Make sure that the Remote Commander has learned the correct signals.
If not, see "For accurate learning" (page 19) and try the learning
procedure again (page 15).
