Panduan Persediaan

1. Pasang Bateri:
   • Open the battery compartment on the back of the main clock unit. Insert 4 new AA batteries, observing polarity (+/-).
   • Open the battery compartment on the wireless outdoor sensor. Insert 2 new AAA batteries, observing polarity (+/-).
   • Ensure both units are powered on within 3 minutes of each other for successful pairing.
2. Gandingan Sensor: The outdoor sensor will automatically attempt to pair with the main unit. A signal strength indicator will appear on the clock's display once connected. If pairing fails, press the "CHANNEL" button on the main unit to re-register the channel, or re-insert batteries in both units.
3. Atomic Time Synchronization (WWVB):

   The clock will automatically attempt to receive the WWVB atomic signal from Fort Collins, Colorado. This usually occurs overnight. Place the clock in an area with good reception, away from large metal objects or electronic interference. A tower icon will appear on the display when the signal is successfully received.

   To manually initiate atomic signal reception, press and hold the "DOWN/RCC" button for 3 seconds. The clock will begin searching for the signal.

4. Tetapkan Zon Masa: Press the "UP/ZONE" button repeatedly to cycle through the available time zones (EST, CST, MST, PST, AKST, HST) until your desired time zone is displayed.
5. Pemilihan Unit Suhu: Press the "DOWN/RCC" button briefly to switch between Fahrenheit (°F) and Celsius (°C) for temperature display.

• Penunjuk Rendah Bateri: An icon will appear in the upper right of the screen when batteries are low.

Button Functions (Rear of Unit):

Note: The clock can display readings from up to 3 outdoor sensors. Use the CHANNEL button to switch between them or enable auto-cycling.

Penyelenggaraan

• Penggantian Bateri: When the low battery indicator appears, replace all batteries in both the main unit and the outdoor sensor. It is recommended to use high-quality, non-leaking batteries (e.g., Lithium batteries) to prevent damage to the device, especially for long-term use.
• Pembersihan: Wipe the clock and sensor with a soft, dry cloth. Do not use abrasive cleaners or chemicals, as they may damage the display or casing.
• Peletakan Sensor: For optimal performance and longevity, place the outdoor sensor in a shaded area that is protected from direct sunlight and heavy rain. While the sensor is splash-proof, prolonged exposure to harsh weather conditions can affect its accuracy and lifespan.

Menyelesaikan masalah

Tiada Paparan atau Paparan Samar:

Check battery polarity and ensure batteries are fresh. Replace all batteries if necessary.

Outdoor Temperature/Humidity Not Displaying or Inaccurate:

• Ensure batteries in the outdoor sensor are fresh and correctly installed.
• Press the "CHANNEL" button on the main unit to re-establish connection or cycle through channels.
• Move the outdoor sensor closer to the main unit to improve signal strength. Avoid large metal objects or thick walls between the units.
• Ensure the sensor is not in direct sunlight, which can cause artificially high temperature readings.

Atomic Time (WWVB) Signal Not Received:

• Place the clock near a window or in an open area, away from electronic devices that may cause interference.
• Manually initiate signal reception by holding the "DOWN/RCC" button for 3 seconds.
• Note that signal reception can be affected by atmospheric conditions, geographical location, and time of day (best reception is often overnight).

Incorrect Date/Day of Week:

Ensure the correct year is set if manually setting the time, as this can affect the calendar function. The atomic signal should correct this automatically once received.
