WARRANTY
The RFL 9300 comes with a ten-year warranty from date of shipment for replacement of any part which fails
during normal operation. RFL will repair or, at its option, replace components that prove to be defective at no
cost to the Customer. All equipment returned to RFL Electronics Inc. must have an RMA (Return Material Au-
thorization) number, obtained by calling the RFL Customer Service Department. A defective part should be re-
turned to the factory, shipping charges prepaid, for repair or replacement FOB Boonton, N.J.
RFL Electronics Inc. is not responsible for warranty of peripherals, such as printers and external computers. The
warranty for such devices is as stated by the original equipment manufacturer. If you have purchased peripheral
equipment not manufactured by RFL, follow the written instructions supplied with that equipment for warranty
information and how to obtain service.
WARRANTY STATEMENT
The RFL 9300 is warranted against defects in material and workmanship for ten years from the date of ship-
ment. During the warranty period, RFL will repair or, at its option, replace components that prove to be defective
at no cost to the customer, except the one-way shipping cost of the failed assembly to the RFL Customer Ser-
vice facility in Boonton, New Jersey. RFL warrants product repair from the one-year from the date of repair or
the balance of the original factory warranty, whichever is longer.
This warranty does not apply if the equipment has been damaged by accident, neglect, misuse, or causes other
than performed or authorized by RFL Electronics Inc.
This warranty specifically excludes damage incurred in shipment to or from RFL. In the event an item is re-
ceived in damaged condition, the carrier should be notified immediately. All claims for such damage should be
filed with the carrier.
NOTE
If you do not intend to use the product immediately, it is recommended that it be opened im-
mediately after receiving and inspected for proper operation and signs of impact damage.
This warranty is in lieu of all other warranties, whether expressed, implied or statutory, including but not limited
to implied warranties of merchantability and fitness for a particular purpose. In no event shall RFL be liable,
whether in contract, in tort, or on any other basis, for any damages sustained by the customer or any other per-
son arising from or related to loss of use, failure or interruption in the operation of any products, or delay in
maintenance or for incidental, consequential, indirect, or special damages or liabilities, or for loss of revenue,
loss of business, or other financial loss arising out of or in connection with the sale, lease, maintenance, use,
performance, failure, or interruption of the products.

CAUTION
FOR YOUR SAFETY
THE INSTALLATION, OPERATION, AND
MAINTENANCE OF THIS EQUIPMENT
SHOULD ONLY BE PERFORMED
BY QUALIFIED PERSONS.
WARNING:
The equipment described in this manual
contains high voltage. Exercise due care
during operation and servicing. Read the
safety summary on the reverse of this page

SAFETY SUMMARY
The following safety precautions must be observed at all times during operation, service, and repair of
this equipment. Failure to comply with these precautions, or with specific warnings elsewhere in this
manual, violates safety standards of design, manufacture, and intended use of this product. RFL Elec-
tronics Inc. assumes no liability for failure to comply with these requirements.

GROUND THE CHASSIS
The chassis must be grounded to reduce shock
hazard and allow the equipment to perform prop-
erly. Equipment supplied with three-wire ac power
cables must be plugged into an approved three-
contact electric outlet. All other equipment is pro-
vided with a rear-panel ground terminal, which
must be connected to a proper electrical ground
by suitable cabling. Refer to the wiring diagram
for the chassis or cabinet for the location of the
ground terminal.
DO NOT OPERATE IN AN
EXPLOSIVE ATMOSPHERE
OR IN WET OR DAMP AREAS
Do not operate the product in the presence of
flammable gases or fumes, or in any area that is
wet or damp. Operating any electrical equipment
under these conditions can result in a definite
safety hazard.
KEEP AWAY FROM
LIVE CIRCUITS
Operating personnel should never remove cov-
ers. Component replacement and internal ad-
justments must be done by qualified service per-
sonnel. Before attempting any work inside the
product, disconnect it from the power source and
discharge the circuit by temporarily grounding it.
This will remove any dangerous voltages that
may still be present after power is removed.
DO NOT SUBSTITUTE PARTS
OR MODIFY EQUIPMENT
Because of the danger of introducing additional
hazards, do not install substitute parts or make
unauthorized modifications to the equipment. The
product may be returned to RFL for service and
repair, to ensure that all safety features are main-
tained.
READ THE MANUAL
Operators should read this manual before at-
tempting to use the equipment, to learn how to
use it properly and safely. Service personnel must
be properly trained and have the proper tools and
equipment before attempting to make adjustments
or repairs.
!
Service personnel must recognize that whenever
work is being done on the product, there is a po-
tential electrical shock hazard and appropriate
protection measures must be taken. Electrical
shock can result in serious injury, because it can
cause unconsciousness, cardiac arrest, and brain
damage.
Throughout this manual, warnings appear before
procedures that are potentially dangerous, and
cautions appear before procedures that may result
in equipment damage if not performed properly.
The instructions contained in these warnings and
cautions must be followed exactly.
