Can’t view JPEG files?
JPEG files without a “.jpg” or “.JPG” or
“.JPEG” filename extension are not recog-
nized.
Use the correct filename extension (page 8).
Only Baseline JPEG files are supported.
Progressive JPEG files are not.
Use Baseline JPEG files (page 8).
Only JPEG files with the following bright-
ness/color difference ratios are supported:
4:4:4, 4:2:2, and 4:1:1.
Use JPEG files with the supported ratio (page 8).
The JPEG file is too big.
Use JPEG files that are less than 5 megabytes
(page 8).
The message “NO
PLAY” appears on the
display?
The disc is dirty. Remove the disc and clean it (page 8).
Buttons on the DPC-7.4
and remote controller
don’t work? Power supply voltage fluctuations and other
anomalies, such as static electricity, can
interfere with normal operation.
Turn off the DPC-7.4, wait five seconds, then turn
it on again. If that doesn’t resolve the issue, dis-
connect the power cord from the wall outlet, wait
five seconds, reconnect it, then try again.
Buttons on the DPC-7.4
work OK but those on
the remote controller
don’t?
There are no batteries in the remote
controller.
Install new batteries (page 15).
The batteries are flat. Replace with new batteries (page 15).
The batteries are installed incorrectly.
Check the batteries and correct as necessary
(page 15).
You’re not pointing the remote controller at
the DPC-7.4’s remote sensor. Point the remote controller at the DPC-7.4’s
remote sensor (page 15).
You’re too far away from the DPC-7.4.
Use the remote controller closer to the DPC-7.4
(page 15). The remote controller has a range of
approximately 16 ft. (5 meters).
A strong light source is interfering with the
DPC-7.4’s remote sensor.
Make sure that the DPC-7.4 is not subjected to
direct sunshine or inverter-type fluorescent lights.
Relocate if necessary.
If the DPC-7.4 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.
■ Abnormal Behavior
The DPC-7.4 contains a microcomputer for signal processing and control functions. In very rare situations, severe interfer-
ence, 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. Alternatively, press and
hold the Stop [ ] button until “RESET” appears on the display (about 10 seconds).
■ Restoring the Default Settings
To reset the DPC-7.4 to its factory defaults, turn it on and, while holding down the Stop [ ] button, press the [Standby/On]
button. “INITIALIZE” appears on the display. When the reset is complete, “COMPLETE” is displayed, and the DPC-7.4
enters Standby mode.
