Initial Set Up and Wireless Synchronization

1. Initialize the Sensor

It is important to

allow sufficient light

to reach the solar

panel while

activating the sensor.

Make sure the lights

are on in the setup room and the solar panel is

facing a 60W light bulb or brighter - do not cover

with hands or other objects. To begin the set up

process, use the included plastic reset rod to

GENTLY PUSH the reset button once in the hole

on the front of the sensor with the LCD/solar panel

facing a light source. All LCD segments will light

up briefly. The code number and the security code

(example: "20") of the model will be displayed

sequentially. Next, the battery voltage will appear

on the LCD. Then the current temperature will

appear on the sensor's LCD and it will start to

transmit the wireless temperature signal.

Note: Sensor battery voltage must be higher than

2.5V to maintain normal operation. When the

voltage of the TX61U-IT sensor is lower than

2.5V, the signal transmission stops and “LO” is

displayed on the LCD for approx. 2 seconds

before the sensor enters the "IDLE" mode. In

"IDLE" mode, the LCD turns off and the sensor

charges up the internal rechargeable batteries

Page 4 of 12

automatically. When the battery voltage charges

to 2.5V, the LCD will turn on and the transmission

of signal will start again.

2. Install Batteries into Wireless Display

Insert 2 new "AA", 1.5 volt ALKALINE batteries

into the wireless display according to the polarity

marked on the battery compartment. Make sure to

do this within 2 minutes of performing the start up

process for the TX61U-IT. (Diagram on page 3)

Once the batteries are properly installed in the

wireless display, the unit will beep and all

segments of its LCD will light up briefly. The

indoor temp and the time (displayed as 12:00) will

appear on the LCD. If it does not appear after 30

seconds, please reinstall the wireless display

batteries and try again. Once the indoor data is

displayed, proceed to the next step.

3. Wireless Temperature Reception

After the wireless display is powered up, it will

start receiving data from the TX61U-IT sensor. If

reception is successful, the outdoor temp will

appear on the wireless display. If the outdoor

temp does not display within 5 min, remove the

batteries from the display and go back to Step 1

(make sure the batteries are fresh).

4. Distance Between Units

To ensure sufficient wireless communication, the

final distance between the wireless display and

the sensor should be no more than 200 ft (60.96

meters) (obstacles can reduce this distance).

TX61U-IT Sensor Power Save "STOP" Mode

If the TX61U-IT sensor is placed in a dark environment

for 24 hours, it will enter into the "STOP" mode to save

power. The LCD will turn off and it will stop transmitting

the data. If this happens, press the reset button on the

TX61U-IT sensor to wake it up. If the voltage is higher

than 2.5V, the LCD will turn on again and resume the

transmission of the wireless temperature signal.

If the voltage is lower than 2.5V, “LO” will appear on

the LCD and the sensor will enter into "IDLE" mode.

Move the sensor to a brightly lit area. In "IDLE" mode,

the LCD turns off and the sensor charges up the

internal rechargeable batteries automatically. When

the battery voltage charges to 2.5V, the LCD will turn

on and the transmission of signal will start again.

Set the Time and Date

The WS-811561 Wireless Display will automatically set

its time based on daily WWVB reception. The signal is

Battery Replacement Information

Wireless Display

To replace the batteries in the wireless display:

1. Lift up the battery compartment cover and remove

the batteries.

2. Please take note to install the batteries with the

proper polarity as it relates to the battery diagram

inside the battery compartment (+). The batteries

will fit tightly. To avoid start-up problems please

ensure that the batteries do not spring free.

3. Replace compartment cover.

Please follow the steps listed in the Setup section of

this manual to ensure that the wireless data reception

is successful.

The TX61U-IT Wireless Solar-Powered Sensor

Does Not have replaceable batteries.

The TX61U-IT uses solar power and automatically

charges the internal power cell(s). No battery

replacement is needed.

Help us to keep our environment clean. Please

take any used batteries to an authorized depot

for recycling.

Page 8 of 12

Installation Notes

Point the TX61U-IT solar panel toward the best

available light source to recharge the batteries, but

avoid a location in direct sun as it will cause incorrect

temperature readings. We recommend facing the solar

panel East to catch the early morning sun, and placing

under an eave or overhang to avoid overhead sun.

The TX61U-IT sensor uses internal rechargeable

batteries to store the collected solar power.

The sensor features a high-efficiency solar panel that

maintains a full charge with minimal indirect light. Do

not place in direct sun, as this will cause incorrect

temp readings.

Fog and mist will not harm the sensor but direct rain

must be avoided.

The TX61U-IT sensor has a wireless range of 200 feet

(60.96 m). Keep in mind that the 200 ft range equates

to an open air scenario with no obstructions, and that

radio waves DO NOT curve around objects. The actual

transmission range will vary depending on the path of

the signal. Each obstruction (roof, walls, floors,

ceilings, thick trees, etc.) will effectively cut the signal

range in half.

Example: If the TX61U-IT sensor, with a 200 feet

(60.96 m) range, is mounted on an exterior wall, the

signal must then pass through one exterior wall, one

interior wall, and across the 10 feet (3 m) width of the

room between the 2 walls to reach the wireless

display. The first wall will reduce the range to 100 feet

(30.48 m), and the second wall will reduce the range to

50 feet (15.24 m). Factoring in the 10 foot room, this

leaves a maximum of 40 feet (12. 2 m) 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.

The TX61U-IT sensor measures and transmits signal

about every 8 seconds when its battery voltage is

higher than 2.5V.

Once the reset button is pressed on the TX-61U

sensor and the batteries are inserted into the wireless

display, the units will try to synchronize

communication. If the wireless display fails to receive

Page 9 of 12

the outdoor temp, this means that the sensor is either

located too close or too far from the wireless display.

Please adjust the location of the TX61U-IT sensor and

try again. If it fails again, please restart the set up

procedure (see below).

Mounting the Units

The TX61U-IT Sensor
