Troubleshooting & Maintenance Lexicon
5-10
Variable output level settings seem ineffective.
Make sure the RT-20 and all associated components are configured
with the correct output level settings. RT-20 variable output levels
do not need to be configured when the RT-20 is connected to an
associated component such as the MC-12 Digital Controller, or
RV-8 Digital Receiver which allows output levels to be calibrated for
analog audio sources. See “Setting Variable Output Levels” on
page 3-14 for more information.
Test Tones will not activate.
1. Press the STOP button to activate stop mode. Test Tones can-
not be activated when playback, resume, or pause mode is acti-
vated.
2. Close the disc drawer. Test Tones cannot be activated when
the disc drawer is open.
3. Set the Screen Saver parameter to Off. Test Tones automatically
mute when the Lexicon screen saver appears on the on-screen
display.
See “Setting Variable Output Levels” on page 3-14 for more
information.
Video Adjust bars exceed the on-screen display margins.
In some cases, the loaded disc might cause the Video Adjust bar to
exceed on-screen display margins. If this occurs, close the Video
Adjust bar and remove the loaded disc from the disc drawer. Then,
open the Video Adjust bar again. See “Video Adjustment/Memory
Banks” on page 3-35 for more information.
Previewed Video Adjust bank settings do not disappear.
1. Select a new Video Adjust bank to cancel the previewed set-
tings. The selected bank settings will be automatically applied
to the picture on the associated display device screen.
2. Press the remote control VIDEO ADJ. button to close the Video
Adjust bar or screen.
See “Video Adjustment/Memory Banks” on page 3-35 for more
information.
Subtitles do not appear on the on-screen display.
Make sure a disc recorded with subtitles is loaded. Subtitles are not
available for discs that are not recorded with subtitles. See “Subtitle
Language” on page 3-5 for more information.
The Parental Lock and Rating Level controls are not available.
Make sure the Parental Lock Password control has been used to
assign a password. The Level control is not available unless a pass-
word has been assigned. See “Setup Menu: PARENTAL SETUP” on
page 3-24 for more information.
The Parental Lock Password has been lost or forgotten.
Restore factory-default settings. Restoring factory-default settings
also resets all Setup and menu parameters to their factory-default
settings and deletes all bookmarks, preferred disc settings, and pro-
gram lists. See “Restoring Factory-default Settings” on page 5-14
for more information.
