BRIEF INTRODUCTION

Thank you for your purchase of this Projection Alarm Clock. 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, calendar, 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 information marked on the battery compartment.
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.

	Main unit is searching for the sensor(s) (the icon will be flashing)
	The sensor(s) cannot be found
	Sensor 1 has been found (the icon will be displayed, but won't flash)
and “--.” (Outdoor temperature Area)	The sensor(s) cannot be found after operating the main unit for 15 minutes

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

• Place the sensor out of direct sunlight and moisture.
• Do not place the sensor more than 30 m (100 ft) from the main (indoor) unit.
• Position the sensor so that it faces the main (indoor) unit, minimizing obstructions such as doors, walls, and furniture.
• Place the sensor in a location with a clear view to the sky, away from metallic or electronic objects.
• Position the sensor close to the main unit during cold winter months as below-freezing temperatures may affect battery performance and signal transmission.

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^ ( 10^ ). Disposable Lithium batteries have a much lower threshold for temperature with an estimated freezing range of below -30^ (- 22^ ).

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), the clock will start to receive the time signals and the signal reception indicator will be flashing for 5 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.

Note

1. If no signals are received or the transmission is interfered, “--” will appear on the display.
2. Relocate the clock or sensor in other positions to try out where your clock receives the signals best. After several trials in vain, please reset the clock thoroughly.

VIEWING THE MIN. & MAX. TEMPERATURE RECORDS

1. In normal mode, press "-MIN./MAX." key twice to show the minimum indoor & outdoor temperature records in the past 24 hours.

2. Press it thrice to show the maximum temperature records.

3. Press it once again to exit.

Note Press and hold it for 3 seconds to delete the minimum and maximum temperature records. MAX.temperature records MIN.temperature records

USING ICE ALERT FUNCTION

If the outdoor temperature range is -2.0^ 3.0^ (28.4°F \~ 37.4°F), 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 transmitter is not enough, and you should replace with 2 AAA size batteries at once. While if the low battery indicator "displays beside the time, it indicates that you should replace batteries of the main unit with 2 new AA size batteries.

Low battery indicator

Note

Attention! Please dispose of the used unit or batteries in an ecologically safe manner.
