How to start your TIMEX@ MARATHON rM
To start your TIMEX MABATHON, simpty push the right
and lelt button simultaneously.
How to operate your TIMEX MARATHON
1. Press the left button to illuminate for viewing in the dark
2. To display the month,/date and then the day, press the
right button once and release. The month/date will be
displayed momentarily. and then the day will be dis_
played momentarily and finally the time will reappear.
On some models the day will be displayed belore the
month,/date.
3. To display seconds, press the right button twice. Seconds
will remain displayed until the right button is pressed
again, and then the time will reappear.
How lo set your
TIMEX MARATHON
Rotate lho lett button so the flat
sid€ is toward the front of the
watch.
To Set Month: Each time the
left button is pressed, a
dittarent function will appear in the
display window of your watch.
Press th€ left button repeatedly
until a number without a colon (:)
appears on the left side ot the
display as illustrated. This number
ropresents a month e.g. 4 is April.
Press the right button and hold in
until the number representing the
proper month appears.

To Set Dala: Press the lott button repeatedly
until the date (no colon shows) appaars on the
right side of the display as itlustratsd. press the
right button and hold in until the proper date
appears.
To Sel Day ol Weok: Press the left button
repeatedly until the day appears on the right
side ol the display. Press the right button and
hold in until the proper day appears.
To Set Hour: Press the lett button repeatedly
until the hour (colon shows) appears on th6 left
side of the display and "A" (AM) or "p" (pM)
appears on the right side of the display as
illustrated. Press th€ right button and hold in
until the correct AM or PM hour appears.
To Set Mlnutes: Press the teft button repeatedty untit the
minute (colon shows) appears on the right side of the
display as illustrated. Press the right button and hold in to
set one or two min ut€s ahead of the correct time. press the
lett button once to display th€ hour and minute (colon not
flashing). At the exact instant when the correct time is the
same as the displayed time, press the right button once
(colon wi ll start tlashing). Seconds are automatically set to
zero when min utes are set. Rotate the left button so ihat the
llat side is toward the back ol the watch. The watch is now
set and the buttons are in the normal operating position.

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.
