NOTE:

• If the location, time, and broadcasting station etc. can be specified through interview with the customer, there is the possibility that the signal reception environment is the cause of the problem.
• Perform confirmation of symptom and evaluate under the conditions that customer reported (location, time, broadcasting station etc).. If this is not possible, confirm problem using similar conditions.
• Before inspection or repair, record the broadcasting stations that customer has preset and reset them accordingly after the inspection or repair. Adjust the clock also.

CONFIRMATION STEP 1: RECEPTION CONDITION SYMPTOM (EXAMPLE)

CONFIRMATION STEP 2: ANTENNA SYSTEM SYMPTOM (EXAMPLE)

CONFIRMATION STEP 3: ANTENNA SYSTEM SIMPLE INSPECTION

• Because the antenna system is equipped with a capacitor, the continuity cannot be checked. Therefore proceed to the following simple inspection.
  • Turn the AM radio on.
  • Tune to the frequency with no broadcast and listen for a buzzing sound.
  • Turn a hand-held light on and shake it around the antenna rod (around 10-20 mm {0.40-0.78 in})
  • If a whirring sound from the speaker synchronized to the work light movement is confirmed, the antenna system is normal.

NOTE:

• Use a fluorescent light type for the inspection.

  Accurate diagnostic cannot be done with an incandescent light.
