WATCH OPERATION
STEP

STEP
2: When
you
want to begin
timing,
simply move
the selector
to the
'RUN'
position
and the display
will
begin counting
up. An
additional feature
is that
other
functions
(such
as
'UTC',
'LOC',
and
'FLT')
are available
while
the stop watch
is counting.

COUNT
DOWN GRAPHIC TIMER
FUNCTION
STEP
1:
First,
you
will
'pre-set' your
timer by moving
the selector
to
the
appropriate'SEC'
(seconds),
'MlN'
(minutes)
and
'HRS'
(hours)
and allowing
each
to
increment
up to
the
desired
value,
then
quickly
moving the
selector to
the
next
desired
position.
When
this is completed,
move the selector
to
'STOP'
to hold
the
current value. lf
you
made
a mistake,
move to the
'RUN'
position
for
a
few seconds,
then set
again.
STEP
2: When
you
are ready to
begin
timing,
move
the selector
to
the
'RUN:
position.
The
graph
will fill to full scale
and the
timer
will
begin counting down. The
graph
now
represents
the
percentage
of 'pre-set'time
remaining.
This is very
handy
for
an instrument
approach
or
for
timing
when to switch fuel
tanks.
It relieves
you
of the
chore
of
noting
clock times
and
calculating
minutes
remaining,
etc.
STEP 3:
When time
expires,
the entire display
flashes
alerting
you
to
this
fact.
Move the selector switch
to the
'STOP'
position
to
clear
the countdown
timer mode.
NOTE:
You can clear the
countdown timer
mode
any time it is running
by
moving the
switch
to
the
'stop'
position.
