Cautions and Warnings
IMPORTANT
IMPORTANT or NOTE indicates a statement that is associated with the task
being performed or information critical for proper equipment function.
CAUTION
CAUTION indicates a hazardous situation that, if not avoided, may result in
minor or moderate injury. CAUTION may also be used to indicate other unsafe
practices or risks of property damage.
WARNING
WARNING indicates a potentially hazardous situation that, if not avoided, could
result in death or serious injury.
Metric Conversion
Metric conversion information is located on the inside back cover of this manual. This information
is provided to assist the operator in cross-referencing non-Metric to Metric conversions.
Recommended Standard Designations
The Recommended Standard (RS) designation has been superseded by the new designation of the
Electronic Industries Association (EIA). References to the old designation may be shown when
depicting actual text displayed on the front panel screen, or on the panels of the pluggable interfaces
(RS-232, RS-485, etc.). All other references in the manual are shown using the EIA designation.

Electromagnetic Compatibility (EMC) Compliance
This is a Class A product. In a domestic environment, it may cause radio interference that requires
the user to take adequate protection measures.
EN55022 - 1997 Compliance
This equipment meets the radio disturbance characteristic specifications for information technology
equipment as defined in EN55022.

EN55024 - 1998 Compliance
This equipment meets the EMC/immunity characteristics for the limits and methods of measurement
for information technology equipment per EN55024-1998.
Federal Communications Commission (FCC)
This equipment 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 a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in
accordance with the instruction manual, it may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference; in which case,
users are required to correct the interference at their own expense.
NOTE
To ensure compliance, properly shielded cables for DATA I/O shall be used.
More specifically, these cables shall be shielded from end to end, ensuring a
continuous shield.
Safety Compliance

Warranty Policy
Comtech EF Data products are warranted against defects in material and workmanship
for a specific period from the date of shipment, and this period varies by product. In most
cases, the warranty period is two years. During the warranty period, Comtech EF Data
will, at its option, repair or replace products that prove to be defective. Repairs are
warranted for the remainder of the original warranty or a 90-day extended warranty,
whichever is longer. Contact Comtech EF Data for the warranty period specific to the
product purchased.
For equipment under warranty, the owner is responsible for freight to Comtech EF Data
and all related customs, taxes, tariffs, insurance, etc. Comtech EF Data is responsible for
the freight charges only for return of the equipment from the factory to the owner.
Comtech EF Data will return the equipment by the same method (i.e., Air, Express,
Surface) as the equipment was sent to Comtech EF Data.
All equipment returned for warranty repair must have a valid RMA number issued prior
to return and be marked clearly on the return packaging. Comtech EF Data strongly
recommends all equipment be returned in its original packaging.
Comtech EF Data Corporation’s obligations under this warranty are limited to repair or
replacement of failed parts, and the return shipment to the buyer of the repaired or
replaced parts.
Limitations of Warranty
The warranty does not apply to any part of a product that has been installed, altered,
repaired, or misused in any way that, in the opinion of Comtech EF Data Corporation,
would affect the reliability or detracts from the performance of any part of the product, or
is damaged as the result of use in a way or with equipment that had not been previously
approved by Comtech EF Data Corporation.
The warranty does not apply to any product or parts thereof where the serial number or the
serial number of any of its parts has been altered, defaced, or removed.
The warranty does not cover damage or loss incurred in transportation of the product.
The warranty does not cover replacement or repair necessitated by loss or damage from
any cause beyond the control of Comtech EF Data Corporation, such as lightning or other
natural and weather related events or wartime environments.
The warranty does not cover any labor involved in the removal and or reinstallation of
warranted equipment or parts on site, or any labor required to diagnose the necessity for
repair or replacement.
