RTC103U Radio Controlled Talking Indoor/Outdoor Thermometer Clock
with wireless remote sensor
The complete unit consists of:
-
One unit of radio controlled talking clock (the main unit)
-
One unit of wireless temperature sensor (the remote sensor)
The radio controlled clock works on the principle of receiving time signals from
the WWVB time signal broadcasting station. If time signal can be received, the
clock will be synchronized with the time of the US Atomic Clock and change to
standard time and daylight saving time automatically. To enhance good receiving
condition, avoid placing the unit near television sets, metal surfaces, computers or
electric devices as these equipment will interfere the reception of radio signals.
Features:
Radio controlled. Adjust time and date and change to standard time and
daylight saving time automatically. Features digital map for easy time zone
recognition and setting.
Human voice time, date, room temperature, outside temperature and alarm
time announcement, features a gentle lady voice.
Big display (128x44mm) for easy reading.
Display time, calendar, room temperature or outside temperature.
Temperature range:
Indoor temperature: 32° to 122°F (0° to 50°C)
Outdoor temperature: -4° to 140°F (-20° to 60°C)
Wireless remote sensor with splash proof design.
Maximum reception range: 20 meter (by calculation).
Voice feedback in every setting step during year/date/time zone/time/alarm
time setting.
Hourly time and temperature announcement during 8AM – 10PM (out of this
range hourly announcement is automatically shut off).
Alarm duration: 2 minutes. 5 minutes snooze function.
Backlight.
PART I – BATTERY INSTALLATION, REPLACEMENT AND SETTING
UP OF THE UNIT
Battery installation and replacement
The main unit uses 2 pieces of AA (or equivalent size) batteries and the remote
sensor uses 2 pieces of AAA (or equivalent size) batteries.
Alkaline batteries are
strongly recommended
. (Lithium batteries are recommended when the remote
sensor is used in extreme temperature.)
Please follow the below procedures to initiate the unit and establish the link
between the main unit and the remote sensor:
Step 1 - Installing batteries to the remote sensor:
Using a screwdriver of suitable size, unscrew and open the back cover. There is a
SLIDE SWITCH with 1-3 selections. Always place the SLIDE SWITCH at
position 1 (position 2 and 3 is reserved for future product enhancement and not
used in this unit). Now install 2 pieces of AAA batteries by following the polarity
marked and press the RESET BUTTON once to initiate the unit.
Step 2 – Installing batteries to the main unit
Open the battery compartment located at the back of the unit. Inside the battery
compartment, there is a “RECEIVE ON OFF SWITCH”. When the switch is set to
“ON” position, the unit will act as a radio controlled clock and will check and
receive the WWVB time radio signal and adjust the time automatically.
Important Note:
If the “RECEIVE ON OFF SWITCH” is set to “OFF” position, the unit will not
check the WWVB time radio signal and will not adjust the time automatically.
Set the “RECEIVE ON OFF SWITCH” to the desired position. Now install 2
pieces of AA batteries by following the polarity marked and press the RESET
BUTTON once to initiate the unit.
Step 3 - Checking the link between the main unit and the remote sensor
Press the MODE BUTTON at the front of the main unit three times to change to
OUTDOOR TEMPERATURE DISPLAY.
When the remote sensor is emitting signal, the front LED indicator will flash. If
the main unit received the signal, the display will show the outside temperature
detected by the remote sensor and the link between the main unit and the remote
sensor is established.
After the link is successfully established, close the battery door and the back cover
of remote sensor. Make sure the rubber ring is placed properly and fasten the
screws. The unit is ready for use now.
Important Notes:
The OUTDOOR TEMPERATURE DISPLAY will show --.- to indicate that the
link between the main unit and the remote sensor is not established. If this is the
case, please try the below procedures:
-
Reset the main unit by pressing the RESET BUTTON once.
-
Repeat Step 3 of the above section.
Battery replacement
1.
The main unit.
Please replace the batteries of the main unit when the display becomes dim or
faded out; or when the voice quality drops or there is no voice. Replace both
batteries with new ones. After batteries replacement, repeat from Step 2 of the
previous section to re-establish the link between the main unit and the remote
sensor.
2.
the remote sensor
Please replace the batteries of the remote sensor when the LED indicator of the
remote sensor is dim or not flashing. Replace both batteries with new ones. After
battery replacement, please RESET the main unit (press the RESET BUTTON of
the main unit once). After reset, repeat from Step 3 of the previous section to re-
establish the link between the main unit and the remote sensor.
Important Notes on installing the unit
Most of the batteries have a working temperature of above 32°F (0°C). When
using this kind of batteries and locating the remote sensor to a place under
32°F (0°C), the remote sensor may not be working under full power or may
work improperly. Under such case, the reception range may be affected or
even caused the remote sensor stop working.
Avoid placing the remote sensor at locations with directly sunlight, rain or
snow.
The reception range may be affected by the construction of the building.
The reception range may be affected, if there are obstacles (e.g. walls, metal
cabinets) between the main unit and the sensor.
PART II – USING THE MAIN UNIT
Receive the time radio signal
The unit will search for time radio signals automatically when it is powered on.
(Note: If the “RECEIVE ON OFF SWITCH” is set to “OFF” position during
battery installation, the unit will not check the WWVB time radio signal and will
not adjust the time automatically.) The radio signal mark on the right of the
display ( ) will start pulsing to indicate that reception is under progress. If time
signal is received, synchronization will take 3-15 minutes and the unit will update
the time and date automatically. The radio signal mark will show three solid
curves (pulsing stopped) to indicate that reception is successful.
IMPORTANT NOTES
1.
During radio signal reception, do not set the time or date manually. Otherwise
the reception will be terminated.
2.
You can start the signal reception manually by pressing the SET BUTTON
once. When the SET BUTTON is pressed, there will be a beep sound and the
radio signal mark will start pulsing to indicate reception is started.
3.
If the unit failed to update the time automatically, after several trials, please
set the time and date manually because:
During daytime, there may be too much external interference that makes
reception failed. Under such situation, please set the time manually
because:
The unit has an automatic process to start reception, when the clock is
showing time between 2-6AM. At midnight, interference dropped to a
minimum level and makes it a perfect environment for time radio signal
reception. If the time of the clock is not set manually when it failed
reception at daytime at the first time initiation, then the automatic
process may start in the daytime everyday (not during midnight) and
eventually keep the unit not receiving the signal.
Please refer to “PART III – MANUAL SETTING THE TIME AND
CALENDAR” on how to set the time and date manually.
Selecting the appropriate time zone
Please select the appropriate time zone before reception started or after radio
signal reception is completed. Otherwise the unit may display incorrect time if the
time zone was not set.
