Issue Possible cause Solution
Reception is very noisy. Atmospheric interference or
lightning, or the DRX-730 is
picking up noise from fluorescent
lighting, motors, or electrical
appliances with a thermostat.
It can be difficult to completely
eliminate this type of noise.
However, it can sometimes be
reduced by connecting an outdoor
AM antenna or by grounding the
antenna (see page 11).
The AM indoor antenna is too
close to the DRX-730.
Move the antenna away from the
DRX-730, or try adjusting the
direction of the antenna.
The DRX-730 is too close to the
TV, particularly if the noise occurs
in the evening.
Move the DRX-730 away from the
TV.
Auto Tuning can’t locate certain
