ABOUT NIST
TheRCW utilizes a highly sensitive radio
receiverto automatically setthe time and
date. TheNationalInstituteofStandards
andTechnology(NIST)measureseach
secondoftimeas9,192,631,770vibrations
ofa Cesium133 atomin avacuum. The
measurementofthe Cesium 133atomis
accurateto one second everyone million
years. Thetime isthen transmitted from
FortCollins, CO to the rest of theUnited
States (US). NIST is the official time used
bythe US; it governs shipmovements,
radiostations, and spaceflights. The RCW
alsoautomaticallyadjusts for daylight
saving time, leap years, and leap
seconds. For more details about
the NIST Clock, please visit
www.NIST.gov
AUTOMATIC TIME SETTING
TheRCW receivesthe NIST signal
automaticallyat 3:00AM everynight. Once
theNIST signal is received the watch will
displaythe officialU.S. time. The time and

Thetime zone thatyou arelocated in must
beselected. Setting the correcttime zone
willallow the watch to set itself to the
correcttime.
Thiswatch should beset manuallyfor the
firsttime. After that, the watch will
automaticallyadjustitselfto maintain
accuratetime.
SETTING THE TIME ZONE
TheRCW willautomatically set the time and
datewhen a NIST signal isreceived
successfully. However, you will still have to
setthe correct timezone.
(Note: The RCWwill not automatically
adjustto anew time zone if you are
traveling. Youmustchange the timezone
settingtocontinue to keeptheexact time.)

SIGNAL SEARCH
AUTOMATICSEARCH
TheRCW is designed to receive the NIST
signalautomaticallyeverynight at 3:00AM.
TheRCW willsynchronize the time and
datewiththe NIST broadcastsignalfrom
Fort Collins, CO. Note: You must set the
watch manually the first time for it to
auto synch during the night.
RECEPTIONSTATUS
Ifthe NIST broadcast is successfully
received,thetower icon inthe upper left
cornerof the LCDwill remain“on” all day.
TheRCW willsearch for the signal again at
3:00AM.
Ifthe reception was notsuccessful, the
towericon will be“off”whichmeans that the
signalwas not received in thepast 24
hours. TheRCW willautomatically search
at3:00AMeveryday to updateits time.
(Note:If the towericon is not“on” in the
upperleftcorner,followtheinstructionsin
theMANUAL SIGNAL SEARCH section).
MANUALSIGNALSEARCH
Whenthe tower iconis not presentin the
upperlefthand corner oftheLCD the NIST
signalhas not been receivedin the
previous24 hours. The RCW searches for
theNIST transmission at3:00AM every
night;which isthe best time to receive the
signal. Inthe event thatyour RCWdoes
nothavethe tower icon displayedthe
RECEIVEbuttoncanbepressed to attempt
toreceive the signal.
1. Pressand hold the RECEIVE button for
tensecondsto activate thesignal
receiver. The tower icon will begin to
flashfor up totenminutes.
2. Donot press anybuttons during the
manualsignalsearch time.
SIGNALSTRENGTH
Whilethe RCWis searchingfor theNIST
signalthe towerwill have rings that blink
arounditto display thestrengthof the
signalbeing received. If thetower only
displaysonering around the towericon,the
receptionis poor inthe area thatyouare
located. Movetoa different area and
attempttoreceivethesignal again.
Ifthe RCWis receivinga strongsignal,
threeringswill be displayedaroundthe
towericon. However,evenwhenastrong
signalis received the RCW may not
automaticallyadjust the timedueto RF
interference.
TIMECHANGEADJUSTMENT
Ifthe RCWreceives theNIST signalat
3:00AMduringthe fall or springtime
change,it will automaticallyadjust to the
correctDaylight Saving Time.
DuringDaylight Savings time,eachtime the
signalis received,the “sun”icon willalso

isimportant that youdo not leaveyour
watchon a metallic surface andkeep it
awayfromany sources of electromagnetic
interference.
Ifyou continue tohaveunsuccessful NIST
signalreception, you may wantto place
yourwatch near awindow where it shows a
