(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 22 for leakage test procedures.

RF Interference Considerations

The NGO 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 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.

Step 4: Soaking

Once the oven temperature reaches the set point, the oven will continue to warm for eight minutes to ensure the cook cavity surfaces absorb enough heat so as to not affect cooking results. This process is called “soaking.”

NOTE: While the oven is soaking, the operator will be able to navigate through the menu, but will not be allowed to cook until the timer reaches 0:00.

-Select “cook more” if the inside of the food item is undercooked

-Select “brown more” if the outside of the food item requires more browning or crisping.

-Select “cook and brown more” if both the inside and outside of the food item are not done.

-Select “save adjusted time” to save any change to the cook time made during Step 6. Note that this option is not available if “Adjust Time” is disabled (page 12).
