How to change your Energy Cell
One Tl MEX Energy Ceil - Type H (1 SO4) - provides the power
to operate your TIMEX MARATHON. To replace the cell,
proceed as lollows:
1. lnsert athin edge into theopening underthe casebackand
carelully pry the caseback off.
2. RemOve the old Energy Cell.*
*Do not dispose of old Energy Cell in fire or attempt to
recharge.
3. lnsert a new Timex Energy Ceil - Type H (1 S04) - with the
positive side facing up (as illustrated).
4. Realign the caseback and press it firmly into ptace. Reset
the month, date, day, and ilme. (Refer to Seiting
lnstructions).
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 on lhe
liquid crystal display to show tha time or the date.

The Liquid Crystal 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 in the dark.

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.
