1) Magnetron heater voltage

4.While looking at the target selected at step 2, straighten it by pressing ! if it is pulled inward, or " if it is pushed outward.

Magnetron heater voltage is formed at the MD Board of the antenna unit and preadjusted at the factory for use with any length of signal cable. Therefore no adjustment is required. However, verify heater voltage as follows:

Note: Turn the power on when measuring magnetron heater voltage.

1.Dismount the shield plate.
