- Renove the battery door of the clock and sensor.
- Insert 4 new AA size batteries to the clock, and 2 to the sensor according to the “+/-” polarity mark on the battery compartment.
- Replace the battery door.
- Once the batteries are inserted, full segment of the LCD will be shown.
- Press [RESET] button of main unit first, and press [RESET] button of transmitter.
- It will automatically receive 433 MHz signal from transmitter for the channel test in 8 seconds.
- After 5 minutes channel test, it will turn to RC signal reception automatically
- The RC clock will automatically start scanning for the radio controlled time
NOTE:
In some cases, you may not receive the signal immediately due to the atmospheric disturbance, the best reception often occurs during nighttime.
HOW TO PAIR MAIN UNIT AND SENSOR
- Press [+/CHANNEL] button on main unit to select a channel.
- On sensor, slide channel switch to corresponding channel. (For additional sensors, select a different channel). Press [RESET] button.
- Press [SENSOR] on main unit to initiate search for 433 MHz reception.
433 MHz WIRELESS SENSOR RECEPTION
If the main unit receives wireless sensor signal successfully, the signal icon displays. While if it cannot receive sensor signal or signal is lost, icon displays.
DAYLIGHT SAVING TIME (DST)
The clock will automatically advance the time by one hour in the spring and back an hour in the fall. Your clock will display “DST” during summer.
RECEPTION OF RADIO CONTROLLED SIGNAL
This RC clock includes a built-in receiver which picks up the signal from the DCF/MSF/WWVB station. Therefore, the clock automatically sets the time, date and weekday.
- The clock automatically carries out four periodic synchronization procedures (at 2:00 AM, 8:00 AM, 2:00 PM and 8:00 PM daily) with the RC signal to correct any deviations to the exact time.
- Once the unit synchronizes successfully to the RC signal, the signal icon” will show up. Each synchronization process will take between 6 to 16 minutes.
- To manually start or stop the RC signal reception, press [RCC] button or press and hold it for 3 seconds.
NOTE:
- The strength of radio-controlled time signal from the transmitter tower may be affected by geographical location or building around.
- Always place the unit away from interfering sources such as TV set, computer, etc.
- Avoid placing the unit on or next to metal plates.
- Closed areas such as airport, basement, tower block, or factory are not recommended.
SIGNAL RECEPTION INDICATOR
The signal indicator displays signal strength in 4 levels. Wave segment flashing means time signals are being received. The signal quality could be classified into 4 types:
RC synchronize process
Weak signal quality
Acceptable signal quality
Excellent signal quality
TIME ZONE SETTING (WWVB VERSION ONLY)
Your clock is designed to display time for different time zones. Please refer to the SETTING THE TIME AND CALENDAR section to set your desired time zone in following order:
PST (Pacific) (Mountain) (Central) (Eastern)
SETTING THE TIME AND CALENDAR
- In normal time mode, press and hold [ TIME SET] button for 3 seconds until the 12/24 Hr flashes.
- Press [+/CHANNEL ]/[ -/ MEM] button to set 12/24 Hour format.
- Press [ TIME SET] button again until Hour digit flashes and press [+/CHANNEL ]/[ -/ MEM] button to adjust its value.
- Repeat above operations to set the time and calendar in this sequence:
- DCF/MSF version: 12/24Hr>Hour>Minute>Second>+/-23 Hour offset WWVB version: 12/24Hr>Hour>Minute>Second>Time Zone
- Press [TIME SET] button to save the setting and return to normal time mode. Or the clock will automatically exit the setting mode after 1 minute without pressing any button.
NOTE:
When setting second, press [+/CHANNEL]/[ -/ MEM] button to set its value to 00.
SETTING THE ALARM TIME
- In normal time mode, press [ ALARM SET] button to enter alarm time mode. Press and hold [ALARM SET] button for 3 seconds until Hour digit flashes.
- Press [+/CHANNEL ]/[ -/ MEM] button to set its value.
- Press [ALARM SET ] button again to step to Minute setting. Press [+/CHANNEL ][ -/ MEM] button to set its value.
- Press [ ALARM SET ] button to save the setting and return to normal time mode. Or the clock will automatically exit the setting mode after 1 minute without pressing any button.
NOTE:
After pressing [+/CHANNEL ]/[ -/ MEM] button, alarm function is automatically turned on (icon “
” displayed).
USING THE ALARM AND SNOOZE
- In normal time mode, press [ ALARM SET] button to enter alarm time mode.
Press [ ALARM SET] button again to turn on (icon “A” displayed) or turn off alarm function.

Snooze can be operated continuously in 24 hours. - Press [ ALARM SET] button to turn off alarm function.
TEMPERATURE AND HUMIDITY
To Select Temperature Unit
Slide [°C/°F] switch on main unit to <°C> or <°F> position.
To Read Outdoor Temperature and Humidity
The default displayed channel is channel 1.
- In normal mode, press [+/CHANNEL] button repeatedly to view readings of channel 1, 2 and 3.
- Press and hold [ +/CHANNEL] button for 2 seconds to enter channel auto-change, and channels change automatically in every 4 seconds.
- Press [+/CHANNEL] again to return to normal mode.
NOTE:
- Once the channel is assigned to one sensor, you can only change it by removing the batteries or resetting the unit.
- If no signals are received or the transmission is interfered, “–” will appear on the LCD.
- Relocate the main unit and sensor in other positions and make sure the transmission is within the effective range of 50 meters approx.
- After several trials in vain, please reset the main unit thoroughly. Try out where your multifunctional main unit receives the signals best.
VIEWING MAXIMUM AND MINIMUM RECORDS
- Press [ -/ MEM ] button to review maximum and minimum indoor & outdoor temperature and humidity records. forecast in next 12 to 24 hours.
- While reviewing the maximum and minimum records, press and hold [ -/ MEM] button for 3 seconds to clear both max & min records.
NOTE:
- Record value will be updated by new higher or low record.
