Press the F button to start the clock when the
actual time value agrees with the entered time.  Colon
will flash at one second intervals when clock is running.
Example for Local Clock Set:
With frequency displayed, suppose it is desired to set
‘13:01’:
Press and hold the 
TIMER
CLOCK button until the colon flashes
rapidly.
Press the following sequence of numeric buttons:
  
BCB 1                            SW 3                            DEL 0                    BCB 1L 00:01             L 00:13             L 01:30         L 13:01
When the actual time is 13:01, Press the 
F button.
The clock is now started.
TIMER OPERATION
The SW8 includes two programmable event timers
allowing the SW8 to turn ON or OFF at preset times.
The timers may be used separately or together and
may recall a currently displayed frequency, memory
channel or a combination of both.  In addition, pro-
gramming only an OFF time provides a Sleep timer;
programming only an ON time provides a Wake timer.
Note that the timers, when activated, respond to the
last displayed clock.
Programming the timers is a two step process.  Step
one is to set the ON and OFF times.  Step two is to
assign a frequency or memory channel to a timer.  This
assignment occurs when the desired timer is actually
enabled.
SETTING TIMER ON/OFF TIMES
Press the 
F button and then hold the TIMER
CLOCK button
for approximately 2 seconds until the ‘TIMER’ annun-
ciator turns on and ON flashes.   The ‘On Time’ will
also be indicated in the frequency portion of the display
(same readout format as the clock) as well as the
number ‘1’ or ‘2’ displayed to the right of the time.
The number ‘1’ or ‘2’ indicates which one of the two
event timers you are programming. TIME DISPLAY
The SW8 incorporates a dual time clock allowing two
24 hour clocks to be set and maintained.  During loss
of AC power, or during battery changing, clock
operation is maintained for a period of approximately
30 minutes, if the SW8 has been connected to an AC
power source or had the batteries installed for a
minimum time of 10 minutes.  The two-event timer
functions are also derived from the last displayed clock,
therefore the clocks must be set first for proper
TIMER operation.  TIMER Settings are also maintained
through a power loss for a period of approximately 30
minutes.
Pressing the 
TIMER
CLOCK button once will display the current
time of the current clock.  After approximately 3
seconds, the display will revert to the current fre-
quency.  Pressing and releasing the 
TIMER
CLOCK button while
time is being displayed will toggle the time display
between the two clocks.  Normally the clock accompa-
nied by the L on the display will be set with the local
time, while the alternate clock will be set to display
GMT (UTC) time.
The SW8 will display the selected clock when the
POWER switch is turned off.
SETTING THE 24 HOUR CLOCKS
Select local (‘L’) or alternate time clock by pressing the
TIMER
CLOCK button.
Press and hold the TIMER
CLOCK button for three seconds until
the colon begins flashing rapidly.  If the ‘L’ is illumi-
nated, you are setting the local clock.  With no ‘L’
displayed, you are setting the alternate clock.  The
keyboard is automatically set up for the shifted (‘F’)
function numeric digit entries in this clock setting
mode. Either clock can be set first.  Time is entered in
a 24 hour format.  Enter the time in ‘HH:MM’, with the
‘colon’ understood.
The 
CLEAR
BEEP button can be pressed to erase erroneous
entries. 
						

							16     Clock and Timer Functions
Press the desired numeric buttons to enter a new ‘ON’
time.  Enter the time in ‘HH:MM’ and in 24 hour format.
Press the 
CLEAR
BEEP button to remove the ‘On Time’ to use
the timer as a Sleep timer.  For a Wake timer, program
an On Time and remove the OFF time.
To set the ‘OFF’ time, Press the 
TIMER
CLOCK  button again to
display ‘OFF time.
Press the desired numeric buttons to enter a new ‘OFF’
time.  Enter the time in ‘HH:MM’ and in 24 hour format.
Press the 
CLEAR
BEEP button to remove the ‘OFF’ time, if
desired.
Press the 
TIMER
CLOCK button again to enter TIMER 2 ON
time.
Press the 
TIMER
CLOCK button again to enter TIMER 2 OFF
time.
Finally, press the 
TIMER
CLOCK button to save the settings and
switch the display to normal readout values.
1)  Example for Setting Timer ‘1’
With frequency displayed, suppose it is desired to set
Timer ‘1’ for a local ON Time: ‘16:59’
                               OFF Time: ‘18:01’

Press the 
F button followed by the TIMER
CLOCK button.
The ‘TIMER’ symbol will light in addition to either or
both the timer ‘1’ or timer ‘2’ indication.  After two
seconds with no entry, the display reverts back to
frequency readout.
Timer ‘1’ can be disabled/enabled by pressing the
numeric digit 
BCB 1 on the keypad while the timer
enable display is showing.
Timer ‘2’ can be disabled/enabled by pressing the
numeric digit 
AIR 2 on the keypad while the timer

If either one or both the timer ‘1’ or timer ‘2’ are
enabled, the TIMER symbol will continue to be
displayed after the receiver is turned off.  Be certain to
leave the volume setting at the desired level.  The
receiver will automatically turn on and off as pro-
grammed.  If both timers are disabled ( ‘-’ - is dis-
played), the timer programming in either or both
timers is retained, but no TIMER action will take place
until one or both are enabled. Prior to enabling either or both timers, consider one of
two possible cases for each timer:
eg.) - To Enable TIMER 1 —
1)  - is displayed: Press the 
BCB 1 button to
display 1.
2)  1 is displayed: Press the 
BCB 1 button twice to
again display 1.
It is important to note that the timer is enabled only
when the timer is deliberately changed from a ‘-’ to ‘1’,
or ‘-’ to ‘2’.
Even if the ‘1’ or ‘2’ is already displayed, the timer is
not enabled unless the ‘-’ to ‘1’ or ‘2’ transition occurs.
Setting a ‘-’ for either timer DISABLES the respective
timer. 
						

							2)  Example for Setting Overlapping Events:
With frequency displayed, suppose it is desired to
record a one hour program on one frequency with a
beginning time of ‘16:59’ and an
ending time of ‘18:00’;
and a second program on the same frequency with a
beginning time of ‘18:00’ and an
ending time of ‘19:01’.

To set an event with no memory channel to be
recalled, exit the memory mode before enabling the
event.  In this case, the SW8 maintains its current
settings.  Refer to ENABLING/DISABLING TIMER
OPERATION to enable or disable either of the two
timers. 
						

							AUTOMATIC BANDWIDTH SETTING WITH MODE
SELECTION DISABLE (ENABLE)
The SW8 permits automatic setting of the bandwidth
appropriate for each mode of detection.  For example,
the 6.0 kHz bandwidth would be selected automatically
for AM mode operation; the 2.3 kHz bandwidth would
be selected for SSB mode.  Of course, pressing the
BW 6 button temporarily overrides the automatic
setting until a mode change is made.  The setting,
automatic or manual bandwidth selection with mode, is
held in nonvolatile memory and is not lost during
power loss or during battery changing.  To disable the
automatic bandwidth with mode,
With POWER OFF,
Press and hold the 
BW 6 button while pressing the
POWER button to put the SW8 in the POWER ‘ON’
mode.
To enable the automatic bandwidth selection with
mode operation, repeat the same procedure. The SW8 has several special features that are referred
to in the main body of this Owner’s manual but may
require additional explanation.
LOCK ALL ENTRY TO KEYPAD
The receiver keypad and tuning control may be locked
or disabled by pressing and holding the 
F button for
3 seconds.
Press the 
F button and hold for 3 seconds.  Ac-
knowledge beep will indicate that the keypad and
tuning control are locked.
Repeat the procedure to unlock the keypad and tuning
control.
10 kHz/9 kHz BROADCAST BAND TUNING STEP
SIZE
In the AM broadcast band, the SW8 increments the
frequency in 10 kHz steps when pressing the 
 or 
buttons.
The 10 kHz step size is practical for tuning the U.S. and
Canadian broadcast bands.  The step size can be
changed to 9 kHz to permit practical tuning of Euro-
pean broadcast stations.  The tuning step size is held in
nonvolatile memory and thus is not lost during power
failure or battery changing.  To select the alternate step
size,
With POWER OFF
Press and hold the 
BCB 1 button while pressing the
POWER  button to put the SW8 in the POWER ‘ON’
mode.
If the step size was 10 kHz prior to performing the
above procedure, then the 9 kHz step size for the
broadcast band is now programmed.  To change back
to 10 kHz, repeat the same procedure.
DELETE ALL MEMORY CHANNELS
If it is desired to delete all programmed memory
channels, perform the following procedure:
With POWER OFF,
Press and hold the 
DEL 0 button while pressing the
POWER button to put the SW8 in the POWER ‘ON’
mode.
Hold the 
DEL 0 button until a confirmation beep is
heard to indicate that ALL memory locations have been
cleared.
