Federal Communications Commission Notice
Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has
established Radio Frequency (RF) emission limits to provide an interference-free
radio frequency spectrum. Many electronic devices, including computers, generate RF
energy incidental to their intended function and are, therefore, covered by these rules.
These rules place computers and related peripheral devices into two classes, A and B,
depending upon their intended installation. Class A devices are those that may
reasonably be expected to be installed in a business or commercial environment. Class
B devices are those that may reasonably be expected to be installed in a residential
environment (that is, personal computers). The FCC requires devices in both classes to
bear a label indicating the interference potential of the device as well as additional
operating instructions for the user.
The rating label on the device shows which class (A or B) the equipment falls into.
Class B devices have an FCC logo or FCC ID on the label. Class A devices do not
have an FCC logo or FCC ID on the label. Once the class of the device is determined,

Electrostatic Discharge
To prevent damage to the system, be aware of the precautions you need to follow when
setting up the system or handling parts. A discharge of static electricity from a finger
or other conductor can damage system boards or other static-sensitive devices. This
type of damage can reduce the life expectancy of the device.
To prevent electrostatic damage, observe the following precautions:
Avoid hand contact by transporting and storing products in static-safe containers.
Keep electrostatic-sensitive parts in their containers until they arrive at static-free
workstations.
Place parts on a grounded surface before removing them from their containers.
Avoid touching pins, leads, or circuitry.
Always be properly grounded when touching a static-sensitive component or
assembly.
AIT Drive Reference Guide B1
Electrostatic Discharge
Grounding Methods
There are several methods for grounding. Use one or more of the following methods
when handling or installing electrostatic-sensitive parts:
Use a wrist strap connected by a ground cord to a grounded workstation or
computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm
10 percent resistance in the ground cords. To provide proper ground, wear the
strap snug against the skin.
Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps
on both feet when standing on conductive floors or dissipating floor mats.
Use conductive field service tools.
Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have a
Compaq authorized reseller install the part.
NOTE: For more information on static electricity, or for assistance with product installation,
contact your Compaq authorized reseller.

Data Compression
The AIT tape drive ships from the factory with data compression enabled for writing.
The drive is equipped with Adaptive Lossless Data Compression (ALDC) algorithm.
In this mode, data is always compressed when writing to the cassette, but the drive is
capable of reading both compressed and uncompressed cassettes.
For the drive to write uncompressed data, you must change the data compression
setting. This can be changed through software or using the DIP switches (see Figure
D-1). Consult your backup application software documentation for the data
compression enabling and disabling procedure.
