Features
- Containing no rotating or moving part as in hard disk drives, thus best suited for applications which
require high environmental resistance (to temperature, humidity, vibration, shock) and for
continuous operation for extended periods of time.
- Never making any sound such as motor rotation sound or access noise during seeking, thus best
suited for applications which require complete silence.
- Lower in power consumption than hard disk drives
- The product comes with a protective function that minimizes disk failures during an instantaneous
stop. *1
*1 This function is not designed to protect files (or data) written onto the disk.

Thi
s e
quip
men
t has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with th
e instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful
interference at his own expense.

About write endurance
PC-ESD series have a write endurance which limits the number of times each memory may be written,
due to the characteristic of the memory that is used. For the write endurance when the size of the data
written is256KB or less, refer to the "Write endurance" listed in the specification.
For the write endurance when the size of the data written is over 512KB, use the calculations below to
obtain an estimated value.
Write endurance (cycles) =
Total capacity (MB) x the NAND flash memory life span (cycles) / Size of file (MB)
Example1: When the file of 1MB is made for CF-2GB-B, and it rewrites it once a second.
Write endurance = 1920MB x 100,000 cycles / 1MB = 192,000,000 (cycles)
Longevity = 192,000,000 / (3600 x 24 x 365) ≈ 6 (year)

WARN ING
- Do not modify the product. Doing so may cause fire, electric shock.
- If smoke or abnormal odor is detected, immediately turn off the PC and peripheral devices and unplug the power
cables.
- Never touch this product with a wet hand. Doing so can short-circuit the product to cause fire, electric shock,
and/or failure.
CAUTION
- Use only the mounting screws (M3 x 6) provided with the product. Longer screws may damage the interior of
the product.
- This product is the silicon disk drives for PC/AT compatible (DOS/V compliant) IDE hard disk.
- No part of this document may be copied or reproduced in any form by any means without prior written consent of
CONTEC CO., LTD.
- The contents of this document may be changed in the future without prior notice.
- All relevant issues have been considered in the preparation of this document. Should you notice an omission or
any questionable item in this document, contact your retailer.
- Regardless of the foregoing statement, CONTEC assumes no responsibility for any errors that may appear in this
document or for any results of using the product.
- The silicon disk is limited in the number of times they can be written (rewritten) to due to the nature of its
memory used. Note that the write life depends on the actual operating conditions.
- Do not turn off the power during disk access (writing). Doing so may break the data.
- The product comes with a protective function that prevents the disk from damaging during an instantaneous stop
but this function is not designed to protect data written onto the disk. When protecting data, use it under the
condition which has no instantaneously stops.
- This product is not formatted. Please be sure to format before use.
