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. Backlighting may be left on
continuously if desired.
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?
This jack is an RS232-compatible Serial Data I/O jack. It is
used for sending weather data to a personal computer or
other external device, such as The Weather Picture, Weather
Vox, or a radio transmitter. It is also used for connecting the
optional Indoor Temperature Sensor.
An additional Serial Data Output port is located in the junction
box (labeled "
