Battery installation
EN

Clock
Open the battery cover on the clock and insert 4x new AA batteries,
observing the correct “+” and “-“ polarity.
The unit can be placed onto any at surface by using the built-in stand,
or placed onto any wall using the wall mount at the back of the unit. It is
recommended you place the clock near a window or in a location with good
reception as the automatic time setting requires a strong radio-wave signal.
Outdoor Remote Sensor
Open the battery cover on the sensor and insert 2x new AA batteries,
observing the correct “+” and “-“ polarity.
The outdoor remote sensor should be securely mounted to a wall using
the wall mount hole located at the back. There is also a pullout stand that
can be used to place the outdoor remote sensor on a at surface. It is
recommended to place the unit in a dry, shaded area to protect it from
direct elements.
Low Battery Indication
The low battery icon will appear on the display indicating the batteries
should be replaced
Outdoor Temperature Synchronization
The remote sensor will automatically transmit the temperature to the clock
after the batteries are installed. The clock will also automatically search for
the signal from the remote sensor for a few minutes after the batteries are
installed. When the clock is searching for the remote sensor, the icon will
appear on the display of the clock.
If the outdoor temperature is not displayed after three minutes, hold the
OUTDOOR TEMP SYNC button for three seconds to search for the signal again.
Getting started

Losing Synchronization of the Outdoor Remote Sensor
If the clock had received the outdoor temperature successfully, but now
displays a blank value (--.-), the synchronization between the outdoor remote
sensor and the main unit may have been lost. Press and hold OUTDOOR TEMP
SYNC button on the clock for three seconds, the icon will appear and the
clock will attempt to search for the outdoor temperature for a few minutes to
re-initiate the synchronization with the remote sensor.
If the outdoor temperature is not displayed after three minutes, replace the
batteries in the outdoor remote sensor, bring the remote sensor closer to
the main unit and try the above steps again.
NOTE: The transmission range can be impacted by extreme cold
temperature, metallic or electronic objects, as well as obstructions and
interferences. You may need to experiment with various locations to get the
best results.
When the batteries are replaced in the outdoor remote sensor (or the reset
button of outdoor remote sensor is pressed), you will need to press and hold
OUTDOOR TEMP SYNC button on the main unit for three seconds to re-initiate
the synchronization, otherwise the signal will not be recognized by the main
unit.
Daylight Savings Mode
• Slide the DST switch to AUTO, when the RCC function is ON, and the
clock is in an area where the RC-WWVB signal can be received.
NOTE: the icon will appear on the LCD during daylight saving time.
• Slide the DST switch to OFF to turn off Daylight savings mode
• Slide the DST switch to ON, and the time will change to daylight saving
time automatically, whether the RCC function is ON or OFF.
Time Zone
Slide TIME ZONE switch to select the time zone, there are 8 time zone for
selectable:
Hawaii = HST
Alaskan = AKST
Pacic = PST
Mountain = MST
Central = CST
Eastern = EST
Atlantic = AST

Automatic Clock Set up: RCC WWVB Reception:
NOTE: Ensure the RCC switch is set to ON, to enable automatic clock set up.
When the RC function is set to ON:
After powering up, if the RCC switch is set to ON the clock will automatically
start to synchronize with the WWVB radio wave signal. The Radio Control
Icon will ash on the LCD.
The clock can be set to scan the time signal manually by holding the WAVE
button for 3 seconds.
Reminder:
• Reception can take up to 10 minutes
• If the signal is weak, it can take up to 24 hours to get a valid signal.
• The clock automatically synchronizes with the radio wave signal at
3:00am every day to ensure accurate timing. If reception fails, the icon
will disappear from the LCD.
• You can stop the clock from automatically synchronizing by holding the
WAVE button for 2 seconds.
Manual Clock Set Up: RCC function is set to OFF
NOTE: Ensure the RCC switch is set to OFF, to disable automatic clock set up.

Troubleshooting
• Use a pin to press the RESET button if the clock is displaying the incorrect
time, even when the radio-control icon is visible on the display. This may
happen when the external noise is strong enough to interfere with the
time signal.
• Press the RESET button on the outdoor remote sensor if the readout is
incorrect or does not respond.
Precautions
• The clock loses its time information when the battery is removed.
• Set up the outdoor remote sensor away from direct sunlight and rain.
• Do not subject the clock to excessive force or shock.
• Do not expose it to extreme temperatures, direct sunlight, dust, or
moisture.
• Avoid contact with corrosive materials. Do not clean the device using
abrasive or corrosive materials or products. Abrasive cleaning agents may
scratch the plastic parts and corrode the electronic circuits.
• Do not tamper with any of the internal components of this clock. This
may cause damage to the components.
