Arrows indicate a rising, steadyor falling trend.WEATHER FORECAST INDICATORThe built-in barometer can notice atmosphere pressurechanges. Based on the data collected, it can predict theweather conditions in the forthcoming 12-24 hours.Note:1. The accuracy of a general pressure-based weatherforecast is about 70% to 75%.2. The weather forecast is meant for next 12 to 24 hours.It may not necessarily reflect the current situation.3.

7142. Insert 2 x AA size batteries into the battery compartment.Make sure you insert them the right way according tothe polarity information marked on the batterycompartment.3. The receiver can receive humidity and temperature data.Channel 1 is the default channel. Make sure the small switch in the battery compartment is set to Channel 1.Press the “RESET” button in the battery compartmentwith a pin or paperclip to confirm the channel is set.Select the temperature unit by pressing the “°C/°F” button in the battery compartment with a pin or paperclip.4. 5.6. Replace the battery door.NOTE:1. Avoid placing the transmitter in direct sunlight, rain orsnow.SETTING UP THE WEATHER STATION1. Remove the battery door and insert 3 x AA size batteriesinto the battery compartment. Make sure you insert themthe right way according to the polarity informationmarked 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.VIEWING THE CHANNELThe 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 RECORDChange the temperature unit to ºC for Celsius or ºF forFahrenheit by pressing the “ºC/ºF” key.Note:1. If no signal are received or the transmission isinterfered, “—-” will appear on the LCD.2. Relocated the clock or transmitter in other positionsand make sure the transmission is within the effectiverange of 100 meters approx.3. After several trails in vain, please reset the clockthoroughly. Try out where your multifunctional alarmclock receives the signal best.CHECKING AND DELETING MAX./MIN. TEMPERATURE &HUMIDITY RECORDS1. Press the “MIN/MAX” key once to check the maximumtemperature and humidity records. Press it twice tocheck the minimum records. Press it again to exit.2. Press and hold the “MIN/MAX” key for 3 seconds todelete the maximum and minimum temperature &humidity records.
8 13NOTE:1.2.The building material and the position of receiver andtransmitter affect the effective range. So try variouslocations to obtain the best result.Place the units away from metal objects and electricalappliances to minimize the interference. Position thereceiver and transmitter within the effective transmissionrange: 30 meters in usual circumstances.DAYLIGHT SAVINGS TIME (DST)The clock has been programmed to automatically switchwhen the daylight savings time is in effect. Your clock willshow “DST” during the summer.RECEPTION OF RADIO CONTROLLED TIME SIGNALThe time and date are radio-controlled. The current timeand date are automatically synchronized with the timesignal transmitted from U.S.A (WWVB)When used for the first time (after inserting the batteries orpressing the “RESET” key), the clock will start to receive theRC signal in 5 minutes with the signal strength indicatorflashing.1. Get the atmosphere pressure data of the sea level (it isalso the relative atmosphere pressure data of your homearea) through the local weather service, internet andother 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 settingmode, or let it exit automatically 30 seconds later withoutpressing any key.NOTE:1. The default relative atmosphere pressure value is 1013mb/hPa (29.91 inHg), which refers to the averageatmosphere pressure.2. When you change the relative atmosphere pressurevalue, the weather indicators will change along with it.3. The built-in barometer can notice the environmentalabsolute atmosphere pressure changes. Based on thedata collected, it can predict the weather conditions inthe forthcoming 12-24 hours. Therefore, the weatherindicators will change according to the detected absoluteatmosphere pressure after you operate the clock for 1hour.4. The relative atmosphere pressure is based on the sealevel, but it will change with the absolute atmospherepressure changes after operating the clock for 1 hour.
912SIGNAL STRENGTH INDICATORThe signal indicator displays signal strength in 3 levels.Wave segment flashing means time signals are beingreceived. The signal quality could be classified into 3 types:If the RC clock receives signal successfully, a sync-timesymbol “ ”will appear on the LCD.The unit has already synchronized with the time signaltransmitter. Otherwise the segment will disappear from theLCD display.NOTE:You may use the “°C/°F” key to receive the time signalmanually. Be caution of using the RECEIVE mode, whichwill consume more battery power and thus may reduce thebattery lifetime. The RECEIVE mode will be off automaticallyin 6-12 minutes.SUGGESTION:Make sure you read the instructions before operating thisdelicate clock. We have developed this sophisticatedinstrument for the best reception performance; however, thesignal transmitted from USA Atomic Clock transmitter willbe affected in certain situations. We advise you to note thefollowing instructions:2. The dual-alarm (ALM1 & ALM2) design of this unit willprovide you with more convenience, and you can settwo-alarm time if needed.USING ALARM & TEMPERATURE PRE-ALARM FUNCTIONS1. 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 offboth alarm1 and alarm2, with the icons disappear.NOTE:1. If set the temperature pre-alarm is ON, the temperaturepre-alarm can sound 30 minutes earlier than the alarmonly when the outdoor temperature is below -3°C (26°F).2. If no key is pressed during the alarm period, the alarmwill turn off automatically. You can press “SNOOZE/LIGHT” key to stop the current alarm and enter thesnooze mode. With the bell icon keep flashing.3. Once the snooze function is turned on, the 4-stepcrescendo alarm will sound 13 times in 5-minuteinterval. The alarm duration is 120 seconds.RELATIVE ATMOSPHERE PRESSURE SETTINGThe “rel” display on the LCD is the abbreviation of “relative”,which refers to the relative atmosphere pressure based onthe sea level; while “abs” is the abbreviation of “absolute”,which means the absolute atmosphere pressure of yourlocation. You can set the relative atmosphere pressure valueaccording to the following steps:Weak signal qualityAcceptable signal qualityExcellent signal quality
10 111. It is strongly recommended to start this clock at nightand let the clock receive the signal automatically duringmidnight.2. Always place the unit away from interfering sourcessuch 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 orfactory is not recommended.5. Do not start reception in moving articles such asvehicles or trains.TIME AND CALENDAR SETTINGIf you are out of reach of the Radio Controlled transmitter orif the reception is not reachable, the time and calendar canbe set manually, as soon as the signal of transmitter isreceived again, the clock will automatically synchronizedwith the exact time and calendar.1.
