ATT 7 ATT - Press to turn on the built-in 20 dB attenua-
tor to reduce the received signal strength in the AM
broadcast and Shortwave bands as required.  The
attenuator is not active in the FM and Aircraft bands.
Successive depressions of the button toggles the
attenuator on and off.  The secondary function of this
button is the digit ‘7’.
AGC 8 AGC - Press to select either the Slow or Fast
AGC setting for the AM broadcast, Shortwave and
Aircraft bands.  The AGC is not selectable in the FM

SHORTWAVE ‘METER’ BAND DESIGNATOR
ENTRY
To facilitate tuning to particular sections of the short-
wave band that contain many worldwide broadcasts of
news, information and music, the SW8 permits entry of
the ‘METER’ band designator.  In some cases, the
worldwide broadcast station may not announce its
exact operating frequency, but will announce the
‘METER’ band in which it is operating or to which band
it will move to improve worldwide reception at a
particular time of...

alternate sideband if desired.  When AM/SYNC has been
activated, moving the main tuning knob will cause the
SYNC circuit to momentarily disengage (indicated by
‘SYNC’ flashing), then back on again when tuning has
stopped.  AM SYNC does not function on the AIR band,
and will not operate properly on intermittent transmis-
sions such as those encountered on CB radio bands, for
example.  For...

RECALLING A MEMORY LOCATION
To select a specific memory channel, press the SCAN
MEM
button and then enter a two digit number of the
desired memory channel to be recalled.  Make certain
that the successive button depressions are made within
3 seconds of each other.  Other memory channels may
be selected by pressing the 
SCAN
MEM button and entering
two digit numbers.  If a channel number is selected that
is empty, Error will flash.
The large rotary tuning control may be used to tune
from the frequency...

14     Scan Functions
The SW8 provides a time scan function of programmed
memory channels using the 
F button and
SCAN
MEM button.  Scan will begin and end within a 10
channel block of programmed memory channels as
indicated by the most significant digit of the selected
memory channel number.
The receiver will stop at each programmed memory
channel within the block for 5 seconds and then
increment to the next memory channel.  Memory
channels that are programmed to be skipped will not
be scanned.  The...
