NOTE 1

This item is a matched component. If it requires replacement, the

complete oven board should be sent back to the factory for repair

and recalibration. When the repaired and recalibrated board is

returned by the factory, the procedure described in paragraph 4—2b

of the manual should be followed. It may also be necessary to retrim

resistor R11 and/or adjust the value of R80. To do this, set potentio-

meter R12 approximately 2/3 clockwise and, using a high precision

voltmeter, measure the voltage across R45 (located on board at rear

of decade switch assembly) with switch S4 in "10V-20V" position. Trim

R11 and/or adjust the value of R80 (using type RN60 precision resist-

ors) until the voltage across R45 reads close to 10.00 volts.

(An alternative to the foregoing procedure is to return the entire

unit to the factory for repair and recalibration).
