Before Using the DV-SP303/DV-SP303E
Notes:
• The supplied batteries should last for about six
months, although this will vary with usage.
• If the remote controller doesn’t work reliably, try
replacing both batteries.
• Don’t mix new and old batteries, or different types of
batteries.
• If you intend not to use the remote controller for a long
time, remove the batteries to prevent possible leakage
and corrosion.
• Flat batteries should be removed as soon as possible to
prevent possible leakage and corrosion.
To use the remote controller, point it at the DV-SP303/
DV-SP303E’s remote control sensor, as shown below.
Notes:
• The remote controller may not work reliably if the
DV-SP303/DV-SP303E is subjected to bright light,
such as direct sunlight or inverter-type fluorescent
lights. Keep this in mind when installing the DV-
SP303/DV-SP303E.
• If another remote controller of the same type is used in
the same room, or the DV-SP303/DV-SP303E is
installed close to equipment that uses infrared rays,
the remote controller may not work reliably.
• Don’t put anything, such as a book, on the remote con-
troller, because the buttons may be pressed inadvert-
ently, thereby draining the batteries.
• The remote controller may not work reliably if the
DV-SP303/DV-SP303E is installed in a rack behind
colored glass doors. Keep this in mind when installing
the DV-SP303/DV-SP303E.
• The remote controller will not work if there’s an obsta-
cle between it and the DV-SP303/DV-SP303E’s
remote control sensor.
