Temperature and Humidity Readings
The•temperature•and•humidity•reading•displa yed•by•the•cl ock•are•
based•on•measurements•taken•by•the•clock’s•built-in•temp erature•
and•humidity•sensors.•Even•if•there•is•a•sudden•change•in•
temperature•and/or•humidity,•it•can•take•up•to•about•30•minutes•until•
the•reading•is•reflected•on•the•clock•display.•This•is•because•it•take s•
time•for•conditions•inside•the•clock•match•conditions•outside.•Also,•
do•not•leave•the•clock•near•an•air•conditioner•air•outlet•when•using•
sensors.
••• The•clock•takes•temperature•and•humidity•readings•once•every•
minute•(except•while•a•time•setting•operation•is•in•prog ress).
••• Temperature•readings•continue•to•be•taken•at•temperatures•lower•
than•0°C•and•from•40.1°C•and•higher,•but•su ch•readings•a re•
outside•the•guara nteed•range.
••• The•displayed•temperature•reading•will•show•“LO”•when•the•
temperature•is•lower•than•–19.9°C•and•“HI”•when•it•is•higher•than•
49.9°C.
••• The•displayed•humidity•reading•will•show•“LO”•when•the•humidity•
is•lower•than•20%•and•“HI”•whe n•it•is•higher•than•90%.
