8. Antenna
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, the resis-
tance 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 then
press the aluminum foil against wire with your fin-
ger.
