●Cal. S149issuitablefor measuringmassive timedate
inaroadrace,marathonrace,etc.
①Withtheuseofthebuilt-inprinter,themeasured
timedatacanbeprintedoutassoonastheyare
obtained.
②Year,month,dateandtimewhenthemeasurementis
startedcanbeprintedout,andtherefore,itiseasytofile
andkeepthedata.
③Anautostartfunctionisprovided.Bypresettingthe
timewhenthemeasurementisstarted,thestopwatch
startsmeasuringautomaticallyatthedesignatedtime.
④Memoryrecallfunction……Upto300measurement
datacanbestoredinmemory.Measurementdata
obtainedfromthestarttofinishofthemeasurement
isrecordedasablockwithouterasingthedatainthe
previousblock,andupto100blocksofdatacanbe
storedinmemory.
Thisfunctionisvery useful forseparatelykeeping
thedatameasuredatdifferenttimeanddate.
⑤Besides,thestopwatchisequippedwithsuch
convenientfunctionsasID No. functionusefulfor

①By connecting the stopwatch to SEIKO Digital
StopwatchCal. S143,etc.,morethantwostopwatches
canstartmeasuringsimultaneouslyatafixedtime.
Therefore,itispossibletomeasurethetimeinaroadrace
ormarathonatdifferentcheckpointsmoreaccurately.
②Connectedwith a gripswitch(optionalaccessory),the
stopwatchcanbeoperatedmoreeasily.
③Withtheuseofapaperextensionholder(optional

11.REMARKSONTHEBATTERIES
（１）Batterylife
Whenanew normalbattery isinstalled,the stopwatchwill
operateapproximately3years.
＊Ifthestopwatchisusedformorethan3hoursaday,thebatterylifemaybe

●WhenfournewandnormalSUM-3manganesedrybatteries
areinstalled,theprintercanprintapproximately10,000lines
(approx.14rollsofpaper)ifitcontinuouslyoperatesat24℃.
Whenalkaline manganesebatteriesare used,itcan print
approximately20,000lines(approx.28rolls).
＊Ittheprinterisusedatextremelylowtemperatures,thebatterypower
becomesweak,andit cannot print as many linesasitprints atnormal
temperaturerange.Itisrecommended,therefore,thatalkalinemanganese
batteriesbeusedatsuchlowtemperatures.
●Whenthe following conditions occur with the power switch
