The sound changes when I connect my head-
phones?
• When a pair of headphones is connected, the listening
mode is set to Stereo, unless it’s already set to Stereo,
Direct, or Pure Audio. When you disconnect the head-
phones, the previous listening mode is resumed.
Can’t change a setting?
• Not all settings appear on the Basic menu. Select the
Advance menu.
• Some settings are not available while using Net-Tune.
Can’t use an audio adjust function?
• Some audio adjust functions can’t be used with certain
listening modes.
The speaker distance cannot be set as
required?
• If the distance between the furthest and nearest speak-
ers is greater than 20 feet (6 meters), corrected values
suitable for home theater use will be set automatically
(page 43).
The display doesn’t work?
• The display is turned off when the Pure Audio listen-
ing mode is selected.

output, actions are not displayed onscreen.

menu. Select the Advanced menu to access these set-
tings (page 39).

Error Messages
The DTR-8.4 contains a microcomputer for signal pro-
cessing 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
event that this happens, unplug the power cord from the
wall outlet, wait at least five seconds, and then plug it
back in again.
To reset the DTR-8.4 to its factory defaults, turn it on and,
while holding down the [Video 1] button, press the
[Standby/On] button. When the reset is complete,
“CLEAR” appears on the display and the DTR-8.4 enters
Standby mode.
