To receive AM broadcasts better...
The UR 18DSL features a built-in an AM radio antenna.
After tuning in the desired radio broadcast, move the UR
18DSL to determine the position at which to best receive
the broadcast.
About the search function
The search function may be unable to tune in a desired broadcast due to the orientation of the UR 18DSL
or for environmental reasons. Even in such cases, you can tune in the desired broadcast by manually
adjusting the frequency on the UR 18DSL.
About the place of use
The UR 18DSL may not receive radio broadcasts well when placed in a vehicle or building. If placed inside
a building, the UR 18DSL can receive radio broadcasts better when placed near a window.
If the UR 18DSL is placed near equipment (e.g., electric appliance, fluorescent lamp, personal computer)
that produces electromagnetic noise, the sound produced by the UR 18DSL may include noise.
In such cases, move the UR 18DSL sufficiently away from the equipment so as to eliminate the noise.
Highly sensitive long rod antenna up to 920-mm long for FM radio
The UR 18DSL incorporates a long rod antenna (up to
920-mm long) to ensure high sensitivity of FM radio
reception.
About the sensitivity of FM radio reception
(1) The table below lists the FM radio reception sensitivity measured with a special instrument. Lower
values indicate higher sensitivity.

(2) The table below lists the results of an overall evaluation of FM radio reception status. For evaluation,
three items (existence of interference, degree of noise, and radio disturbance) were examined by
listening, and the evaluated radios were graded in terms of five levels.
