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 –USINGTHE 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.
