RT-20 Universal Disc Player Troubleshooting & Maintenance
5-9
Playback does not begin from a bookmarked playback time on
the loaded disc.
The bookmark may have been deleted. The oldest bookmark is
automatically deleted when the third bookmark is created. Book-
marks are automatically deleted when the disc drawer is opened or
when the RT-20 is powered off. All bookmarks are automatically
deleted when factory-default settings are restored. See “Book-
marks” on page 4-14 for more information.
SETUP MENU OPERATION
The Setup menu does not include some parameters.
The RT-20 is manufactured for sale in several different countries.
Certain parameters are not available on some versions.
Setup menu parameters cannot be adjusted.
1. Certain parameters cannot be adjusted when some playback
modes are activated. In addition, certain parameters can be
adjusted when playback is activated, although the setting does
not take effect until stop mode is activated.
2. Certain parameters cannot be adjusted when some disc for-
mats are loaded.
Setup menu parameter settings are cancelled.
1. Parameter settings might not have been stored if the RT-20 was
powered off or standby mode was activated before the Setup
menu was closed. If this occurs, all parameters are reset to their
previously stored setting.
2. All Setup menu parameters are reset to their factory-default set-
ting when a power failure (such as a power cord disconnect)
occurs or factory-default settings are restored.
Whenever possible, power the RT-20 off or activate standby
mode instead of disconnecting the power cord.
Setup menu parameter settings seem ineffective.
1. Certain Setup menu parameter settings have no effect on some
disc formats.
2. If playback is activated, press the Stop button to activate stop
mode. Some Setup menu parameters can be adjusted when
playback is activated, even though the setting does not take
effect until stop mode is activated.
Speaker settings seem ineffective.
1. Certain speaker settings have no effect on some disc formats.
For instance, speaker size settings have no effect on DVD-As
and speaker distance settings have no effect on SACDs.
2. Make sure the RT-20 and all associated components are config-
ured with the correct speaker settings. RT-20 speaker settings
do not need to be configured when the RT-20 is connected to
an associated component such as the MC-12 Digital Controller,
which allows speaker settings to be configured for analog
audio sources. The associated component must not be using
analog audio connections in bypass.
See “Setting Speaker Sizes” on page 3-11 and “Setting Speaker
Distances” on page 3-12 for more information.
