SECTION 3 OPERATION

THE MAIN UNIT

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.
