VIEWING THE CHANNEL

The default channel is Channel 1 . In normal time mode, press “UP” key for 3 seconds, with “beep” tone sound to view the channel 1 temperature and humidity.

HOW TO READ INDOORAND OUTDOOR TEMPERATURE &

HUMIDITY RECORD

Change the temperature unit to ºC for Celsius or ºF for

Fahrenheit by pressing the “ºC/ºF” key.

Note:

1. If no signal are received or the transmission is interfered, “—-” will appear on the LCD.

2. Relocated the clock or transmitter in other positions and make sure the transmission is within the effective range of 100 meters approx.

3. After several trails in vain, please reset the clock thoroughly. Try out where your multifunctional alarm clock receives the signal best.

CHECKING AND DELETING MAX./MIN. TEMPERATURE &

HUMIDITY RECORDS

1. Press the “MIN/MAX” key once to check the maximum temperature and humidity records. Press it twice to check the minimum records. Press it again to exit.

2. Press and hold the “MIN/MAX” key for 3 seconds to delete the maximum and minimum temperature & humidity records.

14

2. Insert 2 x AA size batteries into the battery compartment.

Make sure you insert them the right way according to the polarity information marked on the battery compartment.

3. The receiver can receive humidity and temperature data.

Channel 1 is the default channel.

Make sure the small

4.

switch in the battery compartment is set to Channel 1.

Press the “RESET” button in the battery compartment

5.

with a pin or paperclip to confirm the channel i s set.

Select the temperature unit by pressing the “°C/°F” button in the battery compartment with a pin or paperclip.

6. Replace the battery door.

NOTE:

1. Avoid placing the transmitter in direct sunlight, rain or snow.

SETTING UP THE WEATHER STATION

1. Remove the battery door and insert 3 x AA size batteries into the battery compartment. Make sure you insert them the right way according to the polarity information marked on the battery compartment.

2. Replace the battery door.

3. Press the “RESET” button on the back of the clock with a pin or paperclip to re-start the clock. The clock will synchronize with the transmitter set to default

Channel 1 automatically.

7

NOTE:

1.

The building material and the position of receiver and transmitter affect the effective range. So try various locations to obtain the best result.

2.

Place the units away from metal objects and electrical appliances to minimize the interference. Position the receiver and transmitter within the effective transmission range: 30 meters in usual circumstances.

DAYLIGHT SAVINGS TIME (DST)

The clock has been programmed to automatically switch when the daylight savings time is in effect. Your clock will show “DST” during the summer.

RECEPTION OF RADIO CONTROLLED TIME SIGNAL

The time and date are radio-controlled. The current time and date are automatically synchronized with the time signal transmitted from U.S.A (WWVB)

When used for the first time (after inserting the batteries or pressing the “RESET” key), the clock will start to receive the

RC signal in 5 minutes with the signal strength indicator flashing.

8

1. Get the atmosphere pressure data of the sea level (it is also the relative atmosphere pressure data of your home area) through the local weather service, internet and other channels.

2. Press and hold “mb-hPa/inHg” key for 2 seconds until

“abs” or “rel” icon flashes.

3. Press “UP”/”DOWN” key to switch to “rel” mode.

4. Press “mb-hPa/inHg” key once again until the “rel” atmosphere pressure digit flashes.

5. Press “UP” or “DOWN” key to change its value.

6. Press “mb-hPa/inHg” key to save and exit the setting mode, or let it exit automatically 30 seconds later without pressing any key.

NOTE:

1. The default relative atmosphere pressure value is 1013 mb/hPa (29.91 inHg), which refers to the average atmosphere pressure.

2. When you change the relative atmosphere pressure value, the weather indicators will change along with it.

3. The built-in barometer can notice the environmental absolute atmosphere pressure changes. Based on the data collected, it can predict the weather conditions in the forthcoming 12-24 hours. Therefore, the weather indicators will change according to the detected absolute atmosphere pressure after you operate the clock for 1 hour.

4. The relative atmosphere pressure is based on the sea level, but it will change with the absolute atmosphere pressure changes after operating the clock for 1 hour.

13

2. The dual-alarm (ALM1 & ALM2) design of this unit will provide you with more convenience, and you can set two-alarm time if needed.

USING ALARM & TEMPERATURE PRE-ALARM FUNCTIONS

1. Set the alarm time as described in the previous section.

2. Press “ALARM ON/OFF” key once to turn on alarm1, press it twice to turn on alarm2, with the bell icon“ 1 ”

(“ 2”)displays on the LCD. Press it again to turn off both alarm1 and alarm2, with the icons disappear.

NOTE:

1. If set the temperature pre-alarm is ON, the temperature pre-alarm can sound 30 minutes earlier than the alarm only when the outdoor temperature is below -3°C (26°F).

2. If no key is pressed during the alarm period, the alarm will turn off automatically. You can press “SNOOZE/

LIGHT” key to stop the current alarm and enter the snooze mode. With the bell icon keep flashing.

3. Once the snooze function is turned on, the 4-step crescendo alarm will sound 13 times in 5-minute interval. The alarm duration is 120 seconds.

RELATIVEATMOSPHERE PRESSURE SETTING

The “rel” display on the LCD is the abbreviation of “relative”, which refers to the relative atmosphere pressure based on the sea level; while “abs” is the abbreviation of “absolute”, which means the absolute atmosphere pressure of your location. You can set the relative atmosphere pressure value according to the following steps:

12

SIGNAL STRENGTH INDICATOR

The signal indicator displays signal strength in 3 levels.

Wave segment flashing means time signals are being received. The signal quality could be classified into 3 types:

Weak signal quality

Acceptable signal quality Excellent signal quality

If the RC clock receives signal successfully, a sync-time symbol “ ”will appear on the LCD.

The unit has already synchronized with the time signal transmitter. Otherwise the segment will disappear from the

LCD display.

NOTE:

You may use the “°C/°F” key to receive the time signal manually. Be caution of using the RECEIVE mode, which will consume more battery power and thus may reduce the battery lifetime. The RECEIVE mode will be off automatically in 6-12 minutes.

SUGGESTION:

Make sure you read the instructions before operating this delicate clock. We have developed this sophisticated instrument for the best reception performance; however, the signal transmitted from USA Atomic Clock transmitter will be affected in certain situations. We advise you to note the following instructions:

9

1. It is strongly recommended to start this clock at night and let the clock receive the signal automatically during midnight.

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 SETTING

If you are out of reach of the Radio Controlled transmitter or if the reception is not reachable, the time and calendar can be set manually, as soon as the signal of transmitter is received again, the clock will automatically synchronized with the exact time and calendar.

1. In normal time mode, press and hold the “MODE” key for 2 seconds to enter the normal time setting mode.

2. Press the “UP” or “DOWN” key to change the value of the flashing Hour digit.

3. Repeat the above operations to set time and calendar in this order: Time Zone > Year > Month > Date > DST >

Hour> Minute> Second > Day language.
