3.1 Napájení hodin

1. Insert two AA batteries into the battery compartment on the back of the clock. Ensure correct polarity.
2. Connect the small barrel jack end of the USB power cable to the DC IN port on the clock.
3. Plug the USB-A end of the cable into a 5V/1A USB power adapter (not included) and then into a wall outlet. The clock display will light up.

3.3 Prepare for WiFi Connection (2.4GHz Requirement)

The clock only supports 2.4GHz WiFi networks. Before pairing, ensure your smartphone is connected to your home's 2.4GHz WiFi network.

• Check your WiFi settings: Most modern routers broadcast both 2.4GHz and 5GHz networks. Some routers use separate names (e.g., "MyWiFi" and "MyWiFi_5G"), while others combine them under one name and automatically select the band.
• If your phone connects to 5GHz: If your router combines networks and your phone defaults to 5GHz, you may need to temporarily disable the 5GHz band in your router settings during the pairing process. Consult your router's manual or internet service provider for instructions on how to access and modify router settings.

3.4 Pair the Clock with the App

1. Ujistěte se, že je v telefonu povoleno Bluetooth.
2. Open the Smart Life app. On the home screen, tap the "+" icon in the upper right corner to add a device.
3. On the clock, press and hold the designated pairing button (refer to Figure 2 for button location, often one of the side buttons) for approximately 3 seconds until you hear two beeps, indicating it's in pairing mode.
4. The app should automatically discover the clock (e.g., "JXJHOVV-2868"). Tap "Add" or select the device.
5. Follow the on-screen prompts to enter your 2.4GHz WiFi network name (SSID) and password. The app will then transmit this information to the clock via Bluetooth.
6. Once successfully paired, the clock's WiFi indicator will stabilize, and the app will confirm the addition.
