Diagnostic Software, Trouble Shooting and Test Instructions
In this example 23 is the hexidecimal code of the pressed RC
key. The user can leave the remote-control test by pressing
PLAY on the local keyboard of the DVD player. The remote
control test is successful if a code was received before the user
pressed the PLAY key. Pressing the PLAY key, before
pressing a key on the remote control, gives an error in the
remote control test (note that the remote control test will also
fail if a key on the remote control was pressed but no code was
received). The remote control test does not check upon the
contents of the received code, that is it will not be checked if the
received code matches the key pressed. If desired, the user
can manually check this code by using a code-table for the
remote control key-codes.
