ANSWERS TO A FEW MOST LIKELY QUESTIONS . . .
WHAT IS THE
BUTTON FOR?
This button activates display backlighting, for viewing in a
dark room. Pressing the button once turns backlighting on,
and pressing it again turns it off. It's best to use backlighting
only when needed. This will extend lamp life and assure most
accurate indoor temperature readings. We recommend that
you always turn off backlighting when not in use.
WHAT DOES THE BATTERY SYMBOL MEAN?
The battery symbol (not flashing) means the instrument is
operating from battery power. Likely causes are a
disconnected AC adapter, an AC power outage, or a faulty
AC adapter.
WHAT DOES A FLASHING BATTERY SYMBOL MEAN?
The battery symbol will flash if the battery is weak, or if no
battery has been installed.
WHAT IS THE MODULAR 6 CONDUCTOR JACK ON THE SIDE
OF THE CONTROL UNIT?
It is for sending weather data to a personal computer or other
external device (see "Serial Port" section). This jack is also
used for connecting the optional Indoor Relative Humidity
Sensor.
An optional Duplex Cable is required if you wish to supply
data to an external device and also connect an Indoor
Relative Humidity Sensor.
