INVENTORY OF CONTENTS
1. Wireless Weather Station (Figure 1)
2. Wireless Thermo-Hygro Sensor (TX21U)
and mounting bracket. (Figure 2)
3. 3 each, 1/2” Philips screws.
4. One strip of double sided adhesive tape.
5. Instruction Manual and Warranty Card.
ADDITIONAL EQUIPMENT
(not included)
1. 1 Philips screwdriver.
2. 4 Fresh “AA” 1.5VAlkaline Batteries.
QUICK SETUP
Hint: Use good quality Alkaline Batteries; avoid rechargeable batteries.
1. Have the Wireless Weather Station and thermo-hygro sensor 3 to 5 feet
apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the thermo-hygro sensor first and next into the
Wireless Weather Station.
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the Wireless Weather Station and the thermo-hygro sensor will begin to
communicate with each other, and the display will show both the indoor temperature
and an outdoor temperature. If the Wireless Weather Station does not display both

temperatures after the 15 minutes, please retry the set up as stated above. After both
indoor and outdoor temperatures are displayed for 15 minutes you can place your
thermo-hygro sensor outdoors, and set your time.
The remote temperature sensor should be placed in a dry, shaded area. The remote
temperature sensor has a range of 330 feet. Keep in mind that the 330 feet is in open
air with no obstructions and that radio waves DO NOT curve around objects. Actual
transmission range will vary depending on what is in the path of the signal. Each
obstruction (roof, walls, floors, ceilings, thick trees, etc.) will effectively cut signal range
in half.
Example: A wireless weather station receiver with a 330 feet range is mounted on an
interior wall, so that the signal has to pass through one interior wall, one exterior wall,
and across the 10 foot width of the room between the 2 walls. The first wall will reduce
the range to 165 feet, and the second wall will reduce the range to 87 feet. Factoring in
the 10 foot room, this leaves a maximum of 77 feet of remaining signal range.
This allowance is typically enough for a frame wall with non-metallic siding; however
certain materials can reduce range even further. Metal siding, stucco, and some types
of glass can reduce signal range by as much as ¾ or more, compared to the ½
reduction typical of most obstructions. It is possible to receive a signal through these
materials, however maximum range will be much less due to their tendency to absorb or
reflect a much larger portion of the sensor’s signal.
NOTE: Fog and mist will not harm your thermo-hygro sensor, but direct rain must be
avoided.
DETAILED SET UP GUIDE
I. BATTERY INSTALLATION (When one Thermo-hygro sensor is being used)
1. First, insert the batteries to the Thermo-hygro sensor (see “A. Thermo-hygro
sensor” below).
2. Within 2 minutes of powering up the sensor, insert the batteries to the
Temperature Station (see “B. Wireless Weather station” below). Once the
batteries are in place, all segments of the LCD will light up briefly. Following the
indoor temperature and the time as 12:00 will be displayed. If they are not shown
in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds
before reinserting them. Once the indoor data is displayed user may proceed to
the next step.
3. After the batteries are inserted, the Weather Station will start receiving data
signal from the sensor. The outdoor temperature and humidity should then be
displayed on the Weather Station. If this does not happen after 2 minutes, the
batteries will need to be removed from both units and reset from step 1 and the
signal reception icon is no longer shown.

C. ADDING ADDITIONAL REMOTE SENSORS (OPTIONAL)
The WS-8300U is able to receive signals from 2 additional thermo-hygro sensors . The
following are instructions for the set-up of thermo-hygro sensor units with the WS-
8300U. These extra sensors can be purchased through the same dealer as this unit.
1. Remove all the batteries from the receiver and sensor(s) and wait 60 seconds.
During these 60 seconds, press any button 20 times to discharge any excess
power.
2. Insert the batteries to the first Thermo-hygro sensor.
3. Within 2 minutes of powering up the first sensor, insert the batteries to the
Weather Station. Once the batteries are in place, all segments of the LCD will
light up briefly. Following the indoor temperature and the time as 12:00 will be

8
displayed. If they are not shown in LCD after 60 seconds, remove the batteries
and wait for at least 60 seconds before reinserting them.
4. The outdoor temperature and humidity from the first sensor (channel 1) should
then be displayed on the Weather station. If this does not happen and the signal
reception icon is not shown, after 2 minutes, the batteries will need to be
removed from both units and reset from step 1.
5. Insert the batteries to the second sensor as soon as the outdoor temperature and
humidity readings from the first sensor are displayed on the Weather station.
NOTE: You must insert the batteries into the second sensor within 30
seconds of reception of the first sensor.
6. The outdoor temperature and humidity from the second sensor and the "channel
2" icon should then be displayed on the Weather station. If this does not happen
after 2 minute, the batteries will need to be removed from all the units and reset
from step 1.
7. Insert the batteries to the third sensor as soon as the "channel 2" icon and
outdoor data are displayed on the Weather station. Then within 2 minutes, the
channel 3 outdoor data from the third sensor will be displayed and the channel
icon will shift back to "1" once the third sensor is successfully received. If this is
not happen, user shall restart the setting up from step 1.
NOTE: You must insert the batteries into the third sensor within 30 seconds of
reception of the second sensor.
IMPORTANT: Transmission problems will arise if the setting for multiple
sensors is not followed as described above. Should transmission problems
occur, it is necessary to remove the batteries from all units and start again the
set-up from step 1.
D. VIEWING AND OPERATING WITH MULTIPLE REMOTE SENSOR UNITS
1. To view the temperature of a different thermo-hygro sensor unit, press and release
the SET/CH button. A shift from one “boxed” number to the next should be
observed on the right side of the OUTDOOR LCD.
2. To view the Minimum/Maximum temperature & humidity : first select from which
thermo-hygro sensor to read data (indicated by the “boxed” number). Pressing and
releasing the MIN/MAX button will toggle through the minimum and maximum
indoor temperature, and the minimum and maximum outdoor temperature and
humidity.
3. To reset the Minimum/Maximum readings, press and hold the MIN/MAX button for
5 seconds.
III. MOUNTING
Note: To achieve a true temperature reading, avoid mounting in direct sunlight. We
recommend that you mount the thermo-hygro sensor on an outside North-facing wall
(under the eve of a house is ideal). The sending range is 330 feet; obstacles such as
walls, stucco walls, concrete, and large metal objects will reduce the range. Place the
Wireless Weather Station and thermo-hygro sensor in their desired locations before
