A: INSPECTION

Measure the resistance between antenna terminal

and each antenna wire.

If an antenna wire is OK, resistance will be less

than 1 Ω. If an antenna wire is broken, resistance

will be more than 1 MΩ.

NOTE:

When checking the continuity, wind a piece of alu-

minum foil around the tip of tester probe and press

the foil against wire with your finger.

To locate the broken point, move the probe along

antenna wire.

B: REPAIR

1) Clean the antenna wire and surrounding area

with a cloth dampened by alcohol.

2) Paste a thin masking film on the glass along bro-

ken wire.

3) Apply conductive silver composition (DUPONT

No. 4817) on the broken portion with a drawing

pen.

4) Dry out the deposited portion.

5) After repair has been completed, measure the

resistance in repaired wire.
