Speakers slider.

■

To adjust the volume level of an application that you are using, move 
the slider for the corresponding application.

Follow the steps below to change the microphone recording level.

devices from the sub menu.

2. Select Microphone, and click Properties.

3. On the Levels tab move the Microphone slider to increase or decrease 

the microphone volume level.

1 GB, 2 GB or 4GB memory modules (DDR3-
1333) can easily be installed in the computer.

The available option memory depends on 
TOSHIBA authorization.

If you frequently use your computer at more than 
one site, it may be convenient to purchase an 
additional AC adaptor to be kept at each site in 
order to remove the need to always carry the 
adaptor with you.

An additional battery pack can be purchased for 
use as either a spare or replacement. Please refer 
to Chapter 5, 

 for 

further information.

The TOSHIBA Hi-Speed Port Replicator II 
provides several kinds of ports.

Please refer to the TOSHIBA Hi-Speed Port 
Replicator II User's manual for more details.
