2. Initial Pairing and Time Setting

After inserting batteries into both the clock and the outdoor sensor, place them together for approximately 15 minutes to establish a strong connection. The clock will automatically begin searching for the WWVB atomic signal to set the time and date. This process typically occurs overnight (1:00 AM, 2:00 AM, 3:00 AM, 4:00 AM, 5:00 AM) and the signal icon will become solid upon successful connection.

You can manually set the time zone (EST, CST, MST, PST, AKT, HST), language, date, time, RCC reception, alarm clock, and reception channel (Default channel 1) using the buttons on the back of the unit if automatic synchronization is not immediately successful or preferred.

3. Жайгаштыруу

The clock offers dual installation methods: a table stand for desk placement or hang holes for wall mounting. For the outdoor sensor, place it in an area protected from direct rain and sunlight to ensure accurate temperature readings. The transmission range is up to 328ft (100M) in an open area.
