THE MAIN UNIT
The main unit gives you all the readings and controls. It should be
placed indoors.
The main unit is powered up by the 12V AC adapter.
To install it,
1. Position the main unit and other units within effective range
(109 yards).
2. Insert four UM3 or “AA”-sized alkaline batteries for backup
purpose.
3. Mount the main unit safely in place. Or use its table stand to
place it on a flat surface.
4. Connect the AC power adapter to the main unit and a wall socket.
5. Press the [RESET] button on the main unit to initiate operation.
The main unit will start searching for signals for about four minutes.
Upon successful reception, the readings will be displayed. The
main unit will update the readings at regular intervals.
Note: That if the main unit is operating solely on battery power, the
EL backlight and RS232 connection will be disabled.
LOW-BATTERY WARNING
There are low-battery indicators [
] for the main unit, rain
gauge, baro-thermo-hygrometer, thermo-hygrometer and optional
remote thermo and thermo-hygro sensors. Replace the batteries
when the respective indicators light up.
Note: The readings collected from the thermo-hygrometer and any
optional remote thermo and thermo-hygro sensors share the same
display window. The “OUT” and remote channel will share the same
low-battery indicator. When the battery level of the thermo-
hygrometer is low, the low-battery indicator will turn on. If it is one
of the optional remote sensors, the low-battery indicator will
blink. To locate the channel in question, press the window to scan
through all available devices. The low-battery indicator will stop
blinking if the battery level is low for that one.
