Troubleshooting
Nothing happens when using the Universal Remote.
Make sure the radio is powered.
Verify that the Universal Remote is in the TV mode. Check that the remote control box
is connected to the wall power supply and that the wall power supply is connected to the
AC supply.
Check the batteries in the Universal Remote and change if necessary.
Verify that the TV mode of the Universal Remote is set for a Sony TV.
The LED on the remote control unit blinks slowly.
If no remote operations function, check cable connection to the radio.
Check CI-V address, and baud rate in the R75 and the SWL IR Remote control box. Use
configuration command
0 9 5 Enter Enter
to reset to factory defaults. Then re-program
as necessary.
Verify that the R75 is turned on. If radio is not turned on, the R75 will NAK all
commands except power on.
Check that the CI-V cable on the R75 is connected to the REMOTE jack, which is right
next to the DB9 connector.
Commands that are not implemented in the radio are NAK’d; e.g. initiating speech
synthesis without the speech synthesis module will cause the LED to blink.
The LED on the remote control unit blinks fast.
The configuration mode has been selected and the operation needs to be completed. Push
Mute
to cancel the operation or
x x Enter
to complete the operation. See chart above on
the configuration command parameters.
Some buttons on the control work, and some don’t.
Verify that the Universal Remote TV mode is selected. If CABLE or VCR modes are
selected, only a few buttons will work. The volume control, power, and mute will work
in both modes. None of the other keys will work in cable or VCR mode.
Operate the buttons with more time between button presses. There is a 100 msec delay
between key presses so the remote control unit can tell if the button on the remote is held
continuously or has been released and pressed again. Each press of the remote will cause
a continuous stream of IR pulses to be sent (the LED on the Universal Remote will be lit
continuously). The remote control unit knows that the button has been released if the IR
pulse stream stops for 100 msec or longer.
Erratic Operation of the remote
Check the batteries in the Universal Remote and replace if necessary.
Be sure to aim the Universal Remote at the front panel of the control unit. The IR sensor
is behind the front lens to the left of the LED. This is more critical the further you are
away from the remote control box.
Confirm that the interface cable is connected securely to the radio and the SWL IR
Remote control box.
