SECTION 2 INSTALLATION

The WMR112A operates at 433MHz. No wire installation is required
among units.
The WMR112A has an effective range of 300 feet in an open area.
Position the units within the range and be sure the transmission
path is clear of interference and obstacles.
Note: The thermo-hygrometer should be installed outdoors and in
locations that best measure the weather elements which the
instruments are designed for. As for the baro-thermo-hygrometer,
it must be installed indoors. If you have any optional thermo or
thermo-hygro sensors, they can be installed outdoors or indoors.
THE THERMO-HYGROMETER
The thermo-hygrometer measures outdoor temperature and
humidity. It uses two (2) UM-3 or "AA" size batteries.
Follow these steps to install / replace batteries:
1. Remove the screws on the battery compartment.
RESET
2. Assign a channel to the sensor by changing the channel switch
in the battery compartment of the remote sensor.

the degrees C and degrees F slide switch
4. Insert the batteries strictly according to the polarities shown
therein.
5. Press the [RESET] button.
6. Replace the battery compartment door and secure its screws.
THE BARO-THERMO-HYGROMETER
The baro-thermo-hygrometer measures the atmospheric pressure,
temperature and humidity.
The sensor uses four UM4 or "AAA"-sized batteries.
To install it,
1. Insert alkaline batteries accordingly.
2. Mount the unit where you want to monitor the readings. Or you
can make use of its table stand to place it on a flat surface.
THE MAIN UNIT
