BRIEFINTRODUCTION

Thank you for your purchase of this Indoor / Outdoor

Thermometer. Please read these instructions

carefully and keep the manual well for future

reference.

The receiver unit has a clear and easy-to-read

display that shows the indoor temperature, time,

the maximum & minimum temperature records in

the past 24 hours as well as the outdoor temperature

measured and transmitted from the remote sensors.

It is able to receive and display readings from up to

3 remote sensors.

The 433 MHz technology means no wire installation is

required and you can place the sensors anywhere you

like within 30m (100ft) from the main (indoor) unit.

This product is designed to synchronize its date and

time automatically once it is within range of the

signal from the atomic clock in Germany/England.

RECEPTION OF SENSOR SIGNAL

OPERATING THE MAIN UNIT

1. Remove the battery door and slide “UK/EU”

switch to select the desired country version.

2. Insert 2 new AA size batteries as per the polarity

informationmarkedonthebatterycompartment.

3. Press “RESET” key to restart the clock.

4. Slide “°C/°F” switch to select between Celsius

and Fahrenheit.

5. Replace the battery door.

6. Press “+/CHANNEL” key to select the desired

channel.

Note When the sensor signal is received, the icon

“ ” will be displayed on the LCD.

OPERATING THE SENSOR

1. Remove the battery door and slide

“CHANNEL” switch to synchronize the channel

with receiver.

2. Insert 2 new AAA size batteries as per the

polarity information marked on the battery

compartment.

3. Press “RESET” key to restart the clock.

4. Replace the battery door.

Note

The transmission range may vary depending on

many factors. You may need to experiment with

various locations to get the best results.

Standard Alkaline batteries contain significant

amounts of water. Because of this they will freeze

in low temperatures of approximately -12°C (10°F).

Disposable Lithium batteries have a much lower

threshold for temperature with an estimated

freezing range of below -30°C (-22°F).

Wireless ranges can be impacted by a variety of

factors such as extremely cold temperatures.

Extreme cold may temporarily reduce the effective

range between the sensor and the base station. If

the unit’s performance fails due to low temperature,

the unit will resume proper functioning as the

temperature rises to within the normal temperature

range (i.e. no permanent damage will occur to the

unit due to low temperatures).

RECEPTION OF RADIO CONTROLLED

TIME SIGNAL

The time and calendar are radio-controlled. The

current time and calendar are automatically

synchronized with time signal transmitted from

Germany/England.

When used for the first time (after inserting batteries

or pressing “RESET” key), and then after 5 minutes,

the clock will start to receive the time signal. The

signalreceptionindicator will beflashingfor 7 minutes.

SIGNAL RECEPTION INDICATOR

The wave segment flashing means time signals are

being received. The signal quality could be classified

into 3 types:

Note

1. The unit will automatically search for the time

signal at 2:00 (3:00 or 4:00 is also available if

the signal is not received at 2:00), 8:00, 14:00

and 20:00 each day.

2. Always place the unit away from interfering

sources such as TV set, computer, etc.

3. Avoid placing the unit on or next to metal

plates.

4. Closed area such as airport, basement, tower

block or factory is not recommended.

5. Do not start reception in moving articles such

as vehicles or trains.

TIME AND CALENDAR MANUAL SETTING

If you are out of reach of the Radio Controlled

sensor or if the reception is not reachable, the time

and calendar can be set manually. As soon as the

signal of sensor is received again, the clock will

automatically synchronize with the exact time and

calendar.

1. In normal time mode, press “SET CLOCK”

key once to enter the time setting mode.

2. Press “+/CHANNEL” or “-/MIN.MAX.” key to

change the settings.

3. Press “SET CLOCK” to confirm. The setting

order is: 12/24-hr format, time, +/-23 hours

time difference, year, day/month format,

date.

4. Press “SET CLOCK” key to save and exit the

setting mode.

If the outdoor temperature range is -2.0ºC ~ 3.0ºC

(28.4ºF ~ 37.4ºF), the ice alert indicator light will be

turned on and flash.

BATTERY REPLACEMENT

If the low battery indicator “” displays beside

the outdoor temperature, it means that the battery

power of sensor is not enough, and you should

replace with 2 AAA size batteries at once.

While if the low battery indicator “” displays

beside the indoor temperature, it indicates that you

should replace batteries of the main unit with 2 new

AA size batteries.
