IMPORTANT SAFETY INSTRUCTIONS
WARNING: When operating this oven, strictly adhere to the following safety precautions to
reduce the risk of burns, electric shock, fire, injury, damage to oven or property near oven, or
possible exposure to excessive microwave energy.
GENERAL SAFETY INFORMATION
a Read all instructions before using this appliance.
a Read and follow the specific “Precautions to be Observed to Avoid Possible Exposure to Excessive
Microwave Energy” found on page ii.
a This appliance must be grounded. Connect only to a properly grounded outlet. See “Grounding
Instructions” on page ii.
a Install or locate this appliance only in accordance with the provided installation instructions.
a This appliance should be serviced by qualified service personnel only. Contact the nearest authorized
service facility for examination, repair, or adjustment.
a Keep the cord away from heated surfaces.
a Liquids, such as water, coffee, or tea are able to be overheated beyond the boiling point without
appearing to be boiling. Visible bubbling or boiling when the container is removed from the microwave
oven is not always present.
.
a : The contents of feeding bottles and baby food jars must be stirred or shaken and the
temperature checked before consumption, in order to avoid burns (IEC 60335-2-90).
a Use this appliance only for its intended uses as described in this manual.
a Only use utensils that are suitable for use in microwave ovens (IEC 60335-2-90).
X use corrosive chemicals or vapors in this appliance; it is not designed for industrial/laboratory use.
X : heat liquids or other foods in sealed containers (e.g., jars, whole eggs, etc.) since
they are liable to explode.
X allow children to use this appliance.
X operate this appliance if it has a damaged cord or plug, is not working properly, or has been
damaged or dropped. See “Power Cord Replacement” found on page ii.
X cover or block any openings on this appliance.
X store this appliance outdoors.
X use this product near water (e.g., near a kitchen sink, in a wet basement, near a swimming pool).
X immerse the cord or plug in water.
X let the cord hang over the edge of a table or counter.
X use a water jet for cleaning. See pages 5-7 in this manual for proper cleaning procedures.
X use this product without the bottom jetplate installed. The oven will not cook properly and
damage to the oven may occur.
X This appliance is not to be used by children or persons with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction.
REDUCING FIRE RISK
a Remove wire twist-ties from paper or plastic bags used to facilitate cooking in the oven.
a If materials inside the oven ignite, keep the oven door closed, turn the oven off, and disconnect the
power cord or shut off power at the fuse or circuit breaker panel.
a If smoke is observed, switch off or unplug the oven. Keep the door closed to stifle any flames.
X use the cook cavity for storage purposes.
X overcook food. Carefully attend to the oven if paper, plastic, or other combustible materials are
placed inside the oven to facilitate cooking.
X leave paper products, cooking utensils, or food in the cavity when the oven is not in use.

ii SAFETY INSTRUCTIONS
GROUNDING INSTRUCTIONS
This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of
electric shock by providing an escape wire for the electric current. This oven is equipped with a cord that has
a grounding wire with a grounding plug, which must be plugged into an outlet that is properly installed and
grounded. Consult a qualified electrician or serviceman if uncertain about the ability to follow grounding
instructions or if in doubt as to whether the appliance is properly grounded.
X use an extension cord. If the power cord is too short, have a qualified electrician or
serviceman install an outlet near the appliance.
WARNING:Improper grounding can result in risk of electric shock.
POWER CORD REPLACEMENT
If the power cord is damaged, it must be replaced by the manufacturer, its service agent, or a similarly
qualified person.
PRECAUTIONS TO BE OBSERVED BEFORE
AND DURING SERVICING TO AVOID POSSIBLE
EXPOSURE TO EXCESSIVE MICROWAVE ENERGY
(a) Do not operate or allow the oven to be operated with the door open.
(b) Make the following safety checks on all ovens to be serviced before activating the magnetron or other
microwave source, and make repairs as necessary: (1) interlock operation, (2) proper door closing,
(3) seal and sealing surfaces (arcing, wear, and other damage), (4) damage to or loosening of hinges and
latches, (5) evidence of dropping or abuse.
(c) Before turning on microwave power for any service test or inspection within the microwave
generating compartments, check the magnetron, wave guide or transmission line, and cavity for
proper alignment, integrity, and connections.
(d) Any defective or misadjusted components in the interlock, monitor, door seal, and microwave
generation and transmission systems shall be repaired, replaced, or adjusted by procedures described
in this manual before the oven is released to the owner.
(e) A microwave leakage check to verify compliance with the Federal Performance Standard should be
performed on each oven prior to release to the owner. Refer to page 26 for leakage test procedures.
RF INTERFERENCE CONSIDERATIONS
The Encore oven generates radio frequency signals. This device has been tested and was determined to be
in compliance with applicable portions of FCC part 18 requirements and to the protection requirements
of Council Directive 89/336/EEC on the approximation of the laws of the Member States relating to elec-
tromagnetic compatibility at the time of manufacture. However, some equipment with sensitivity to signals
below these limits may experience interference.
If your equipment experiences interference:
a Increase the physical separation between this oven and the sensitive equipment.
a If the sensitive device can be grounded, do so following accepted grounding practices.
a If battery-powered microphones are being affected, ensure that the batteries are fully charged.
a Keep sensitive equipment on separate electrical circuits if possible.
a Route intercom wires, microphone wires, speaker cables, etc. away from the oven.
