Introduction

Optional Features 7

Volume Control 1

The Macintosh Performa 6400 computer has a push button on the front panel to control

the sound volume of the internal speaker. Sound volume can also be controlled with the

Sound component of the Monitors and Sound control panel. A knob located below the

monitor port on the back of the computer controls the low frequency volume of the

subwoofer.

Power On and Off 1

The user can turn the power off and on by pressing one of two buttons:

■ the Power key on the keyboard

■ the Power key on the remote control (with TV/FM tuner installed)

If ﬁles are still open when the user attempts to turn off the computer by using either one

of the Power keys or the Shut Down menu item, the system displays an alert box

warning the user that ﬁles are open and should be closed to avoid loss of data.

Optional Features 1

Several features of the Macintosh Performa 6400 computer are implemented as plug-in

modules available either as a conﬁguration option at the time of purchase or as a later

upgrade. The modules are designed so that they can be installed by the user.

TV and FM Radio Tuner 1

The TV and FM radio tuner module turns the computer into a television and FM radio

receiver, complete with remote control. The features of the TV tuner module are the same

as those for the TV tuner in the Power Macintosh 5400 computers. The TV picture is in

its own window on the desktop, and the TV signal is carried in YUV format for

improved picture clarity.

The features of the TV tuner module are

■ the ability to remotely tune 181 broadcast and cable channels (U.S. version)

■ a coaxial connector for TV antenna or cable input (F-type connector in U.S. and

Japanese versions; IEC-type connector in Europe)

■ the TV picture is in a resizable and movable window

■ YUV format for improved clarity (see sidebar)

■ support for closed captioning and teletext

■ software password protection

■ automatic and manual channel programming

■ a single remote control for TV, FM radio, and for playback of audio CDs
