Troubleshooting
—Continued
Buttons on the DV-SP503E work OK but those on the remote controller don’t?
• There are no batteries in the remote controller.
Install new batteries (page 11).
• The batteries are flat.
Replace with new batteries (page 11).
• The batteries are installed incorrectly.
Check the batteries and correct as necessary (page 11).
• You’re not pointing the remote controller at the DV-SP503E’s remote sensor.
Point the remote controller at the DV-SP503E’s remote sensor (page 11).
• You’re too far away from the DV-SP503E.
Use the remote controller closer to the DV-SP503E (page 11). The remote controller has a range of approximately 16
ft (5 meters).
• A strong light source is interfering with the DV-SP503E’s remote sensor.
Make sure that the DV-SP503E is not subjected to direct sunshine or inverter-type fluorescent lights. Relocate if
necessary.
• If the DV-SP503E is installed in a cabinet with colored glass doors, the remote controller may not work reliably when
the doors are closed.
Open the doors, or use a cabinet without colored glass.
The DV-SP503E contains a microcomputer for signal processing and control functions. In very rare situations, severe
interference, noise from an external source, or static electricity may cause it to lockup. In the unlikely even that this
should happen, unplug the power cord from the wall outlet, wait at least five seconds, and then plug it back in again.
