IBM AC453A User Manual

There are three audio sources that
can be selected:

• The tuner

• An external source from a laser

disk or VCR

• An internal source, which could

be a sound board or CD-ROM
drive 

The tuner source is selected by
default. The CD or sound board can
be selected with a CD button on the
remote. Pressing this button once
switches the audio to the CD source
and brings up a program to control
the CD-ROM specified in the
PCPT.INI configuration file. By
default this is the MusicBox program
(provided with the Windows
Multimedia Extensions). If no
program is available, the CD is
selected, but no control program is
started. Pressing the CD button a
second time switches the audio back
to previously selected audio source
(either the tuner or the external
source) and closes the control
program. Video and audio inputs
are selected together when the
TV/Video button is used.
The audio source can also be
selected through the Audio dialog
box. The audio dialog box can be
invoked through the Audio option
of the floating menu or the
Configure 

menu on the menu bar. 

It can also be changed by typing A
through the keyboard.

The sleep timer turns the TV off
after a period of time. Program the
time through the Wakeup/Sleep
dialog box in the Configure menu.
There are two ways to enable or
disable the sleep timer:

Use the Sleep button on the
remote. Pressing once enables
the function. Pressing a second
time disables it.

Use the S key on the keyboard to
enable or disable the function.

The wake up function switches to 
a specific channel at a predefined
time. If the TV is iconized or the
power is turned off, wakeup will
switch on the TV. The time is
programmed through the
Wakeup/Sleep

dialog box invoked

via the Configure menu. The
function can be enabled via a check
box in the Wakeup/Sleep dialog
box. This dialog box can also be
invoked using the W key.

The current time can optionally be
displayed at the bottom right corner
of the TV screen. There are two ways
to enable or disable it:

Use the Clock button on the
remote control.

Use the Clock display choice in
the floating menu or the
Configure

menu. 

Use the D key on the keyboard
to turn clock display on or off.
