COMMONLY SEEN PROBLEMS AND
TREATMENT METHOD
. As the electric equipment such as TV set, florescent lamp and electric motor can
produce strong interference to the MW and SW of the radio, please keep a certain
distance with above electric equipments when the radio is used to avoid the
interference.
. The building with reinforcing steel bar structure and high buildings have the effect to
screen the broadcast signal. It is suggested to use the radio close to the window so
as to improve the receiving effect.
. If the receiving site is close to the signal of BB pager station, the receiving of SW will
be interfered seriously. The receiving effect may be improved by shortening the length
and adjusting the angle of the telescopic antenna.
