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 Electronics 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
properly. Equipment supplied with three-wire ac
power cables must be plugged into an approved
three-contact electric outlet. All other equipment
is provided 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
covers. Component replacement and internal
adjustments must be done by qualified service
personnel. 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
maintained.
READ THE MANUAL
!
Operators should read this manual before
attempting 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
potential 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.
