^ It the resistance is less than 1 ohm, continue with step 3.





3. Measure the resistance between the antenna tube and the outside contact of the antenna jack.

^ If the resistance is more than 1 ohm, go to CORRECTIVE ACTION, Antenna Tube Replacement.

^ If the resistance is less than 1 ohm, continue with Coaxial Cable Test.
