A. NOISE
A-1 Noise appears at certain places when travelling (AM).
Is there a particular structure?NoDo the following measures eliminate the
noise?
1. Change to a different station with
a strong signal to boost resistance
to interference.
2. Suppress high tones to reduce
noise.
3. Extend antenna completely.Ye sOK
Ye s
Find out the following information from
the user:
1. Place
2. Locality conditions (valley, moun-
tain, etc.)
3. Name and frequency of stations
affected by noiseNo
If due to vehicle noise:
It may not be possible to prevent noise
if the signal is weak.
If there is more noise than other radios, find out the noise
conditions and the name and frequency of the receiving
stations from the user, and consult with the service centre.
If due to external noise:
In almost all cases, prevention on the
receiver side is impossible. Weak sig-
nals especially are susceptible to inter-
ference.
