MO (MOT) and ED modes are not available when

USING THE ATTENUATOR
To reduce interference or noise caused by strong sig-
nals, you can reduce the scanner's sensitivity to these
signals.
There are two attenuator modes in your scanner. One is
normal attenuator mode in which you set the attenuator
in each channel or each band/group in the search and
tune mode. The other is global mode in which you set
the attenuator only once. This setting is applied all the
time in every mode.
Press
ATT
to turn on or off the attenuator while the chan-
nel number is indicated or while the scanner is searching
through bands/groups. When the attenuator is on,
