3. Opsætning

3.1 Udpakning

Carefully remove all components from the packaging. Ensure you have the main atomic clock unit and the wireless outdoor sensor.

3.2 Batteriinstallation

Both the main clock unit and the wireless outdoor sensor require batteries (not included).

1. Main Clock Unit: Open the battery compartment on the back of the clock. Insert 3 x AA batterier, hvilket sikrer korrekt polaritet (+/-).
2. Trådløs udendørs sensor: Open the battery compartment on the back of the sensor. Insert 2 x AAA batterier, ensuring correct polarity (+/-). For temperatures below -4°F (-20°C), lithium batteries are recommended for the outdoor sensor.

4. Betjeningsvejledning

4.1 Atomic Time Synchronization (WWVB)

The clock automatically synchronizes with the WWVB radio broadcast from Fort Collins, Colorado, ensuring accurate time. This process typically occurs overnight. For best reception, place the clock near a window and away from electronic interference.

Image 4.1: The atomic clock automatically corrects its time daily by receiving the WWVB signal, covering eight time zones and adjusting for Daylight Saving Time.

4.2 Manuel indstilling af tid og dato

In areas where the WWVB signal is weak or unavailable, you can manually set the time and date:

1. Tryk og hold på SÆT knappen for at gå ind i tidsindstillingstilstand.
2. Brug UP or NED knapper til at justere den blinkende værdi (f.eks. time, minut, år, måned, dag).
3. Tryk på SÆT knappen for at bekræfte hver indstilling og gå videre til den næste.
4. The clock will exit setting mode automatically after a few seconds of inactivity or by pressing SÆT repeatedly until all settings are confirmed.

4.3 Temperaturvisning (°C/°F)

The clock displays both indoor and outdoor temperatures. To switch between Celsius (°C) and Fahrenheit (°F):

• Tryk på DOWN/WAVE/°C/°F button to toggle the temperature unit.

4.4 12/24 timers format

Sådan skifter du mellem 12-timers og 24-timers tidsformater:

• Tryk på UP -knappen for at skifte mellem 12-timers (med AM/PM-indikator) og 24-timers formater.

4.5 Alarmfunktion

Sådan indstilles alarmen:

1. Tryk på ALARM knappen én gang for at vise det aktuelle alarmtidspunkt.
2. Tryk og hold på ALARM knappen for at gå ind i alarmindstillingstilstand.
3. Brug UP or NED knapper til at justere time og minut.
4. Tryk på ALARM knappen for at bekræfte hver indstilling.

For at aktivere/deaktivere alarmen:

• Tryk på ALARM button repeatedly to cycle through alarm ON/OFF states. An alarm icon will appear on the display when activated.

5. Vedligeholdelse

5.1 Udskiftning af batteri

When the low battery indicator appears on the display, replace the batteries in the respective unit (main clock or outdoor sensor) promptly to ensure continuous operation and accurate readings. Refer to Section 3.2 for battery types and installation.

5.2 Rengøring

Clean the clock and sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the display or casing.

5.3 Miljøhensyn

The outdoor sensor is designed for outdoor use but should be protected from extreme weather conditions. The recommended operating temperature range for the outdoor sensor is -58°F to 158°F (-50°C to 70°C). For temperatures below -4°F (-20°C), lithium batteries are required in the outdoor sensor for reliable performance.

6. Fejlfinding

• Ingen visning / Svag visning: Check battery installation and replace with fresh batteries if necessary. Ensure correct polarity.
• Ingen udetemperaturmåling:
  1. Ensure batteries are correctly installed in the outdoor sensor.
  2. Verify the sensor is within the 330ft wireless range of the main unit.
  3. Tryk på KANAL button on the main unit to ensure it is on the correct channel (if applicable).
  4. Relocate the sensor or main unit to improve signal reception, avoiding large metal objects or other electronic devices.
• Forkert tidspunkt:
  1. Ensure the clock is attempting to receive the WWVB signal (look for the RCC reception icon).
  2. Place the clock near a window and away from electronic interference for better signal reception.
  3. Manually initiate a signal search by pressing the DOWN/WAVE knap.
  4. If atomic synchronization fails, manually set the time as described in Section 4.2.
• Temperature Readings Seem Inaccurate:
  1. Ensure the outdoor sensor is placed in a shaded area, away from direct sunlight or heat sources.
  2. Kontroller batteriniveauet i begge enheder.
