■ Attenuator
The attenuator prevents desired signals from distort-
ing when very strong signals are near the desired fre-
quency, or when very strong electric fields, such as
from broadcasting stations are near from your location.
The attenuator can be set to both or either band sepa-
rately, and the attenuation level can be set for each
band independently.
➥ Push [ATT] to turn the attenuator ON and OFF.
•“ATT” indicator appears when the attenuator is activated.
DD
Setting the attenuation level
q Push [M/S•BAND] or [SUB] to select the desired
band of the attenuation level to be set.
w Push [SET] then [ATT] to enter the attenuator set
mode.
e Rotate the tuning dial to select attenuation level.
• Push [M-CL 5] to return to the default value.
r Push [SET] to exit the attenuator set mode.
NOTE: When using the noise blanker, received
audio may be distorted if they are excessively
strong.
■ Simple band scope
This function allows you to visually “sweep” an area
surrounding the set frequency for other signals. De-
tected signals are indicated graphically on the S-meter.
q Set the operating frequency and mode.
w Push [SWP 0] to turn the simple band scope func-
tion ON and OFF.
•“SWP” indicator flashes when the simple band scope
function is activated.
•Detected signals are indicated using the S-meter and
“▼” indicator, displayed above the S-meter, shows the
center frequency (displayed frequency).
•The signal availability is detected by the noise squelch
condition (open or close).
e To monitor the detected signal, rotate the tuning dial
to set the appearing “dot” of the S-meter to below
the “▼” indicator.
•The frequency readout shows the detected signal fre-
quency.
DD
Setting sweeping time interval
q Push [SET] then [SWP 0] to enter the sweep set
mode.
w Rotate the tuning dial to select sweeping time inter-
val.
• Push [M-CL 5] to return to the default value.
e Push [SWP 0] to exit the sweep set mode.
