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.
