QQTemperature and Humidity Readings
The•temperature•and•humidity•reading•displayed•by•the•clock•are•
based•on•measurements•taken•by•the•clock’s•built-in•temperature•
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•takes•
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•progress).
•••Temperature•readings•continue•to•be•taken•at•temperatures•lower•
than•0°C•and•from•40.1°C•and•higher,•but•such•readings•are•
outside•the•guaranteed•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”•when•it•is•higher•than•90%.
•••The•displayed•humidity•reading•will•show•“-•-”•when•the•
temperature•is•outside•the•range•of•5°C•to•45°C.
Power Supply
•••Your•clock•runs•on•two•AA-size•alkaline•batteries.
