You can use the internal Timer to start software at a specific time. You can
use this feature when the computer is on or in System Suspend mode.

When selecting software that uses a phone line: The computer may not be able to
disconnect the phone line due to communication and server conditions. Be sure to monitor
the status of the software when running PPK Setup, and manually disconnect the phone line
if you notice a malfunction. Furthermore, when using the Timer to start the software, it is
advised that you set the computer to enter System Suspend or System Hibernation mode
after a certain time. This allows the computer to disconnect the phone line if the computer
fails to disconnect the line normally. However, the computer cannot disconnect the phone
line when it enters System Suspend mode if the internal modem ring resume is set to On.
