BBoA Ase n ™™ Wi-Fi Synchronized Wall Clock User Manual BSN-W7300/BSN-W7400 Series A——Mounting hole B——Wi-Fi button C——HRST button D——Battery Compartment (with cover) Quick start overview Your Boasen clock can automatically calibrate its time and switch to daylight saving time based on your time zone selection. Setup is very simple, install the battery, connect to its hotspot then the settings web page will pop up. Usually,if the guessed time zone is exactly what you need, you only need to set the Wi-Finetwork for it.The general operating steps are outlined below: 1. Install 2 AA batteries correctly. 2. Connect to your Boasen clock via its Wi-Fi hotspot. 3. Open the settings web page that usually pops up automatically. 4. Set up Wi-Fi network. 5. Set up your time zone. 6. Save Settings and install the clock wherever you like. 1. Install AA Batteries Open the battery compartment on the back of the clock. Insert two AA batteries, using the plus (+) and minus (-) guides in the AA battery pack battery compartment to insert the batteries in the proper direction.Insert the plus (+) endfirst and you can easily install the batteries. Additional Information:  The working voltage of your Boasen clock is 2.7V~3.5V, 2 AA batteries are required. It is recommended to use alkaline batteries or 1.5V constant voltage output AArechargeable Batteries. Better battery quality can extend battery replacement cycles.  When replacing the battery, remove the plus (+) endfirst. If it is too tight to remove, it is recommended to use an appropriate small tool. The battery compartment cover also works. However, it may cause slight damage to its appearance surface. 2. Connect to Your Boasen ClockHotspot Your Boasen clock provides an open Wi-Fi hotspotfor setting it up, which you can connect using your smartphone, PAD, laptop or desktop computer, etc. The way to do this is to look for an open Wi-Fi network starting with "Boasen -Clock" and select it to connect. 3. Open the Settings Web Page After the connection is established, your device will automatically pop up the settings page, or prompt you to log in. Tap the prompt to open the settings page in a pop-up window. You can follow the prompts to set it up when you see the settings page. Basically, it only takes two steps to complete the setup: Step 1: Set up Wi-Fi network. (See section 4) Step 2: Set up you time zone. (See section 5) 4. Set up Wi-Fi Network Selectthe Wi-Fi network that you want to use.If it doesn't appear in the drop-down list, you can tap "Wi-Fi Scan" to refresh and wait a few seconds interval until you see it. For hidden networks, you need to type the network SSID manually. 5. Set up YourTime Zone If your wall clock is used to display your local time, the recommended time zone will usually meet your needsand this step can be skipped. If the recommended time zone is incorrect or you need to display the time in other regions, clear the recommended time zone and follow the prompts to find the time zone you need. 6.
