Conventions Used in this Guide
The TD2u has two soft keys placed immediately under the LCD display. The bottom line of the
display shows text indicating the current function for each of the two soft keys. In this guide,
soft key labels are indicated with square brackets. For example,
[Select] indicates that Select is
displayed above a soft key on the display.
Disk Capacity and Transfer Rate Measurement
Conventions
The computer industry generally adheres to two different conventions for the definitions of
the terms megabyte (MB) and gigabyte (GB). For computer RAM, 1 MB is defined as 2
20
=
1,048,576 bytes and 1 GB is defined as 2
30
= 1,073,741,824 bytes. For disk storage, 1 MB is
defined as 10
6
= 1,000,000 bytes and 1 GB is defined as 10
9
= 1,000,000,000 bytes. These two
conventions are known as powers of two and powers of ten respectively. Microsoft deviates
from the hard disk capacity measurement convention and uses the powers of two convention
for its operating systems.
