CHAPTER 4: Operation

4.11 Sleep Timer

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:

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

b.Use the S key on the keyboard to

enable or disable the function.

4.11.1WAKE UP 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.

4.12 Clock Display

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:

a. Use the Clock button on the remote control.

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

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

4.13 Selecting the Audio Source

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.
