How
your
TIMEX MARATHON
works
A schamatic drawing
ot
the TIMEX Oigital timekesping
system
is
shown on
Page10. All
ol
the
system's
major
circuits are integrated into a tiny silicon chip containing
ov6r
2,000 transistors in a
spaca
less than
'l15
ol an inch
on
a side.
Th6
system is
powered
by one small
Tl MEX Energy
Csll. Energyfrom th6call is directed through an oscillator
circuit,
which
causes
the
quartz
crystal
to
s€nd elsctrical
pulsalions
(32,768
times
p€r
second)
to the
divider ci
rcuits.
The dividsr
circuits
thon reduce thes6
electrical
pulses
to
one
pulse per
second.
These
once
per
second
pulses
are
counted and, by m6ans
ol
th€ logic ci rcuits in th€ decoder
section, are directad to tho appropriate el€ctrod€s

The Liquid

Display
(LCD)
System
Your TIMEX MARATHON shows
you
the time, date, day, or
seconds.
But how
does
the
display
work?
ln the TIMEX MARATHON a thin,
transparent layer
of
highly-purified
liquid
crystal
matsrial is soal€d b€tween
glass plates.
These
plates
carry
transparent
electrodes
in
the shape
ol
ssgmontgd numorals.
When
an electrical
field
is
applied across opposite electrod6s,
tha numerals turn
dark, allowing
you
to read the time, date,
day,
or seconds.
With
a
push
ota
button, a light will
illuminate
ths displayto
allow viewing

The
"Excitable" Ouartz
Crystal
Quartz
is
probably
as old as our
planet.
lt
is
a common
mineral
with an uncommon charactsristic. lt seems inert.
But when connected to
proper
electronic circuits,
it will
pulsate
at a
steady, unvarying
rate
The
quartz
crystal in
your
TIMEX
MARATHON is designed to vibrate
32,768
times
per
second, and the
rhythm
of these
pulsations
is
extremely
stable.
Thus,
the
quartz
crystal creates a dependable time
standard,
maintaining
a constant
rate
with
great precision.
Care and Servicing of
your
TIMEX MARATHON
CARE: llthetime displaywindow becomes damaged,
have
it replaced at once. When
your
TIMEX En€rgy Cell'.is
deplated, it should b€ replaced
promptly.
We recommend
that
you
use a
gen
uine
TIMEX Energy Cell,
Type
H
(1
504).
lt
may be obtained from
your
local
TIMEX Retailer or
Authorized TIMEX Warranty Service Center.
i
SERVICE; lf
your
TIMEX MARATHON should ever
need
servicing, either send
it
to
TIMEX address€d as lollows:
PRODUCT SERVICE
P.O. BOX 2740
LITTLE ROCK, AR.72203
or
take it to an Authorized TIMEx
Warranty
Service Centsr.
