Reception

1. Test radio with vehicle outside and hood closed.
Check radio reception in an area away from tall buildings, metal structures, power lines, fluorescent lighting, and power tools.
2. Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
3. Check antenna coax connectors for corrosion or bad connections.
4. If a test antenna is used, ground base of the antenna to vehicle body.
Coated screws or bolts can act as poor grounds. Do not use threadlocker, or similar material, on bolts because it will insulate the ground path.
