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.

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 ground- ing instructions or if doubt exists as to whether the appliance is properly grounded.

†x D O N O T use an extension cord. If the power cord is too short, have a qualified electrician or service- man install an outlet near the appliance.

W A R N I N G : 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 quali- fied person.

RF INTERFERENCE CONSIDERATIONS

The NGC (Tornado) 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 require- ments of Council Directive 89/336/EEC on the approximation of the laws of the Member States relating to electromagnetic compatibility at the time of manufacture. However, some equipment with sensitivity to signals below these limits may experience interference.

If your equipment experiences interference:

†Increase the physical separation between this oven and the sensitive equipment.

†If the sensitive device can be grounded, do so following accepted grounding practices.

†If battery-powered microphones are being affected, ensure that the batteries are fully charged.

†Keep sensitive equipment on separate electrical circuits if possible.

†Route intercom wires, microphone wires, speaker cables, etc. away from the oven.
